Need To Know About Ball Valves

A ball valve is type of a shut-off valve that stops, starts, and changes the flow of gases, liquids, and vapors in a pipe system by turning a ball inside the valve. The ball is affixed to two seats and is linked to the operating and control mechanism that causes its rotation via a shaft. The cross-section of the bore is perpendicular to the flow area, and the valve restricts the passage of the fluid. The rate at which the fluid flows through the valve is proportional to the bore’s area interacting with the floor.

The fundamental way of functioning a ball valve requires an operator’s manual turn of a lever or a wrench. To open or close the valve, torque is utilized to rotate the lever arm 90° in either a clockwise or counterclockwise direction. A parallel lever arm to the pipes indicates an open valve. Ball valves are available in various styles and configurations to meet the diverse requirements of industries. The specifications and standards for ball valves differ by industry in which they are used.

General Applications For Ball Valve

Ball valves are often used to shut off fluid flow in domestic and offshore oil and gas production facilities. They are also used to feed burners with fuel gas. It is the function of ball valves to control the flow of high-pressure liquids and gases with little pressure drop. These valves can quickly open and close because they have a very low response time. They can also seal tightly with minor force.

For example, ball valves can be used as shut-off valves for homes, businesses, and other places in air conditioners. The design, the closing material, and the welds should all work together to make a safe structure that meets the most challenging needs, like high working pressure when using refrigerants like R410A.

In the yard, ball valves can be used for different types of watering. You can connect these valves to taps, outdoor hoses, watering cans, or sprinkler lines. Stop the main water flow while you connect the ball valve to the main water line. Add water to the mains through one of the ball valve’s ports.

Fabricating Types of Ball Valves

Each ball valve intended for particular applications, such as gas ball valves, will also be labeled accordingly. Regardless of the specific ball valve variety under consideration, the majority will comprise four primary components. The components include the valve housing, the central metal ball, the seating mechanism that secures the ball within the valve, and the lever used to turn the ball valve from the on/open to the off/shut state. Typically, stainless steel, brass or nickel-plated brass, P.V.C., or a comparable robust plastic polymer compose the body of a ball valve. Typically, the spheres are crafted from brass or stainless steel, with nickel-plated or chrome-plated brass being the most common materials. Another way distinct ball valve models and configurations are differentiated is by the numerous attachment or fitting types. Manual ball valves with compression fittings or threaded fittings may be among these. Complex designs of ball valves may provide additional flow control options beyond the standard on/off function. Both flanged and vented ball valves are available; the position of the lever can determine which one produces which flow outcome. Your application, the nature of the fluid to be regulated, the required flow rate, and the pressure rating of your system will impact which variety of ball valves is most suitable. 

full port ball valves vs standard port
v port valve

Full Port Ball Valves

In a full bore, the diameter of the bore is similar to that of the pipe. In full-bore valves, the flow area of the fluid remains constant, resulting in an exceptionally low flow resistance. Due to the minimal frictional loss encountered during fluid flow, the pressure decrease is also minimal. An increased pressure decrease in a piping system complicates the process of pumping. However, due to the need for the bore diameter to correspond to the pipe size, a more extensive housing and ball are necessary, resulting in a higher cost than a reduced bore.

V-Port Ball Valves

A v-port ball valve is a type of control valve that consists of a v-shaped ball or seal. The ‘V’ design facilitates fluid regulation. The molded v-bore differentiates v-port ball valves from other varieties of ball valves. 

V-port ball control valves are generally preferred for fluid regulation due to their ability to produce linear flow characteristics. The flow properties of a v-port ball valve differ from those of standard port ball valves. As the shaft rotation of a v-port ball valve increases, fluid flow has a corresponding linear increase.

cavity filler ball valves
3 way ball structure

Cavity Filler Ball Valves

The seat design of a cavity-filled ball valve links the distance between the ball and its body. This prevents the accumulation of particles or entrapped media around the ball over time, both of which have the potential to obstruct the fluid flow or cause contamination. Ball valves with cavities are less challenging to maintain and sanitize. Cavity-filled ball valves are invaluable in sectors where sanitation is of the utmost importance, such as the food, pharmaceutical, and bioprocessing industries.

Multiport Ball Valves

Multiple fluid streams are diverted, combined, divided, or turned off via multi-port ball valves using a ball with an L-shaped or T-shaped bore segmented through its center. A multi-port valve can divide a flow upstream to the inlet into multiple discharge streams. Although it can divide a flow, it cannot allocate it to its outflow streams at predetermined flow rates. Additionally, it can join several flow streams into a solitary stream or change the flow direction of the fluid.

trunnion ball valve structure
float valve

Trunnion Ball Valves

In a trunnion ball valve, the ball is supported by a trunnion, an extra tube at the bottom. This stops the ball from moving and keeps it in place along its axis. The valve shaft has to turn for the ball to move. The pressure of the fluid moving the springs toward the ball held by the trunnion. This makes a tight seal. They are also excellent for high-pressure situations because the fluid pressure is spread to the trunnion and the seat springs. 

Floating Ball Valves

The floating ball valve is the most popular type of ball in ball valves. Even when the valve is closed, the ball can move from side to side because it is hanging inside. The valve is held in place by two seats that support and keep it in place. The ball fits into a hole in the shaft on one end, leaving the other open. When the valve is open, the ball can’t move side to side because the shaft is connected to the slot on top of the ball.

What Is the Difference Between One-Piece, Two-Piece, and Three-Piece Ball Valve?

1-piece, 2-piece, and 3-piece ball valves, while all falling under the umbrella of ball valves, have distinct characteristics that make each suitable for particular applications.


One-Piece Ball Valve

An internal component housing a one-piece ball valve is a single-piece cast body of the ball valve. This effectively diminishes the potential for fluid leakage from the valve. One-piece ball valves are the most suitable ball valve type with a reduced bore. The welded one-piece ball valve is more prevalent but cannot be disassembled for cleansing or repair after damage. Consequently, it is restricted to applications where sanitation is not a significant concern and particulate accumulation is unlikely. In contrast, the disassembly of screwed one-piece ball valves necessitates specialized equipment, while servicing, repair, and cleaning are all possible.

Two-Piece Ball Valve

A two-piece ball valve comprises a housing divided into two interlocking parts. The ball is contained in the main piece, which is also connected to one end, while the internal components are held together in the secondary piece, which is also connected to the other. Housings consisting of two pieces are the most prevalent on ball valves. The two components are detachable for cleansing, maintenance, and inspection; however, this process necessitates the extraction of the valve from the conduit.

Three-Piece Ball Valve

A three-piece ball valve housing contains internal components that are secured and fastened to its two extremities via fastener connections. Welded or threaded are attached to the primary pipe. Three-piece ball valves are utilized in applications that are highly dependent on valves and require frequent maintenance. Three-piece ball valves are frequently employed in industries where sanitation is critical to product quality and safety, such as the food and beverage and pharmaceutical sectors.

Depending on the particular demands of the application, each form of ball valve may be produced from an extensive array of materials, such as bronze, brass, stainless steel, and others. 

What Are the Components of Ball Valve?

Ball valves, extensively utilized in industrial, commercial, and residential settings, are comprised of several vital components, each essential for their efficient operation. These components are frequently accessible as spare parts, facilitating efficient valve maintenance and repair throughout its operational lifespan. The primary spare parts for ball valves are as follows:

ball valve's spare parts


 The body or valve enclosure contains all internal components of a ball valve. The ball valve’s components are safeguarded by a thermoplastic or thermoplastic-lined metal structure composed of a hard and rigid material. It also gives access to the external control mechanism responsible for the ball’s rotation.

Rotatory Ball

The primary distinguishing feature that sets ball valves apart from other valves is the presence of a center opening or aperture in the ball. By this central hole, the media is directed. Through one axis, this aperture connects the inlet to the outflow.


The stem is the interface between the rotary ball and an external control system in a ball valve. For instance, the stem is linked to a handle or actuator in a manually operated ball valve.


The bonnet conceals the orifice in the ball valve visible through the body’s opening. Additionally, it functions as a pressure boundary.The packaging encircles the stem and acts as an impenetrable barrier to the substance.


Discs are utilized as supports between the body and the projectile. They provide support and a barrier between the object and the body. The seats of the ball valves uniformly distribute the seating tension and function as a seal to enclose the fluid.

Handle or Actuator

It must be supplied with energy through a manual or actuated power source. Automatically actuated energy is powered by an electric, hydraulic, or pneumatic source. In contrast, manually operated actuators require the manipulation of handles and levers.

Rotatory Ball

The primary distinguishing feature that sets ball valves apart from other valves is the presence of a center opening or aperture in the ball. By this central hole, the media is directed. Through one axis, this aperture connects the inlet to the outflow.


Gaskets are vital sealing components that prevent leaks between various valve body parts. They significantly contribute to the waterproof characteristic of ball valves.The packaging encircles the stem and acts as an impenetrable barrier to the substance.

Normal Sizes for Ball Valves as Manufacturing

Ball valves come in various standard sizes designed to fit different piping systems. These standard sizes are often referenced by the nominal pipe size (N.P.S.) they’re meant to accommodate. Here are the most common sizes:

2pc ball valves

Ball Valve Size





¼ inch




3/8 inch




½ inch




¾ inch




1 inch




1 ½ inch




2 inch




These sizes indicate the internal diameter of the pipe connections in the valve. The measurements may vary marginly depending on the regional standards, such as the American National Standards Institute (ANSI) or British Standard Pipe (B.S.P.). Always consult a professional or follow the ball valve manufacturer’s guidelines when selecting the right size for your application.

What Are the Different Types of Ball Valves Connections?

To properly connect to process lines or other parts, ball valves need different end connections depending on their use and where they are installed. Different connection types accomplish the same thing: connecting both sides of the ball valve to the pipe or part. However, some connection types work better in certain situations.These are some popular ways to connect a ball valve:

Installation plumbing parts monkey wrench construction brass plumbing fittings gate valve on fitting

Threaded connections: 

Threaded connection ends make it simple to attach tiny valves to pipelines. The valve usually has female threaded ends that join to a male threaded part. The valve may have two male-threaded ends or one male-threaded end and one female. To make the threads, strict adherence to thread standards is required. These standards describe the thread’s properties.

Tri-Clamp Connection:

It’s also called a Tri-Clover or a T-Clamp. A Tri-Clamp is a flanged link where a flexible clamp with a seal in the middle holds together the flanged ends of the pipe and valve. Tightening the clamp squeezes the pipe and the valve end together, ensuring the link is sealed. Clamps come in several styles, including single hinge, three-segment double hinge, and two-bolt high pressure.

Socket Weld Connections: 

This kind of welded connection has a valve that is wider than the pipe so that the pipe can fit into the valve socket end. The weld is done around the edge of the end of the valve that fits on the pipe.

Flanged Connections: 

For valves larger size than 4, flanged connections are preferred. They are simple to implement and can be taken out for upkeep and cleaning without affecting other pipe network parts. Metal pieces with holes in them are called flanges. Bolts and nuts are used to attach the valve to the pipe. These parameters describe factors like how the plates should be made, the size and thread of the holes, and where the holes should be located.

Butt-welded Connections:

The connection is welded, so the valve and pipe ends are the same size. The ends of the link are pressed against each other and cut to make room for the weld. Welding is done around the edges of the joint. Smaller pipe sizes often use butt welding.

True Union Connection:

Most P.V.C. valves and pipes use true union connections, where the pipe’s outside diameter fits the connection’s inside diameter. To stop leaks, a chemical (glue) is used. They make it possible to connect and separate the ball valves from the pipe more than once, which is useful for repair or replacement. Often, P.V.C. parts are used in acidic liquids like seawater, acids and bases, and organic solvents.


Ball Valves Types Manufacturing

Ball valves  types of applications. Understanding their differences is key in selecting the right Ball valve for a given task.

Ball valve applications in plumbing system

A ball valve is type of a shut-off valve that turns a ball inside the valve to start, stop, and control the flow of gases, liquids, and vapors in a pipe system. Three parts connect the ball to the machine that moves and controls it: two seats, a shaft, and the machine itself. Flow can’t go through the valve if the opening’s cross-section isn’t straight across from the flow area. The valve lets water flow; how much of the hole can be seen from the floor depends on how open it is.

The way the ball valve works is similar to how the butterfly valve works. It is made up of a sphere with a hole drilled through the middle of it. The flow is either open or closed based on where the circular opening is placed. The ball is linked to the stem, which is linked to the handle or activator of the tool.

To start the fluid flow, the pump turns about 90 degrees clockwise. It turns the stem, which makes the ball turn. When the ball’s opening lines up with the fluid path, the valve lets fluid move through. The actuator turns 90 degrees counterclockwise, the stem turns the same way as the ball turns 90 degrees counterclockwise, and the flow of fluid stops.

To control the flow, the ball can be kept in both partially open and partially closed. When there is a high-pressure drop and the valve is left partly open for a long time, the flexible seats flow around the ball’s opening edge. They might be able to stop the ball in its path.

Ball Valve Specifications

As a ball valve manufacturer-Plumberstar, we are able to provide and identify more difference ball valve and gate valve here.

gate valve and ball valve

Ball valves for home appliances:

Many home plumbing systems use ball valves to let main water or branch blockages happen when leaks happen. They are also used in model home appliances like water faucets, heaters, bathrooms, and washing machines.

Ball valves for refrigerators:

Ball valves are shut-off valves in home air conditioners, industrial HVAC, and refrigerators. When working with refrigerants like R410A, the welds, design, and closing materials should help ensure the production is safe under the toughest conditions, such as high working pressure.

In the oil and gas business:

Ball valves are often used as liquid shutdown valves in gas and oil production facilities on land and at sea. They are also used to keep gas heaters running smoothly. It is suggested that ball valves control the flow of fluids and gases with high pressure while causing the least pressure drop. They have the right amount of low reaction time, which means they open or close quickly, and these regulators can fit tightly with little force.


Ball Valve Maintenance

The best way to ensure it works well for a long time is to fix it often. In the first year of use, check the valve for any signs of leaks. Every three months, move the handle to open and close the valve four times.

Gate Valves Maintenance

As you install gate valves, check to see if there is any damage there. Clean the valves at least once a month when you’re not using them. This will keep the outside and inside from getting grimy with dust and dirt.  

Media and the Port:

Gate Valves: When fully open, gate valves have a full port design that makes it easy for fluids to flow through. They are often used for thick media and slurries because the flow is straight through them.

Ball Valve: When it comes to ball valves, they come in full-port, reduced-port, and V-port styles. Like gate valves, full port ball valves let fluid flow through with little resistance when fully open. But the smaller V-port designs let you control fluid flow better, making ball valves more useful.

Even though both types have excellent features, the best valve type for your application would depend on its needs. Before making a choice, you should always talk to an expert in the field or a reputable valve maker. This short outline compares the two types of valves in a basic way. However, the best choice will depend on your system and purpose.

brass gate valves details

Stainless Steel Vs. Brass Ball Valves

When choosing a ball valve for a particular application, the material selection plays a significant role. Here’s a comparison of stainless steel and brass ball valves on some key aspects:

3pc stainless steel ball valve

Stainless steel with exceptional resistance is produced by alloying chromium and nickel with iron. This material is ideal for shut-off and control applications because stainless steel ball valves are known for their resistance to leakage, ability to withstand a broad range of temperatures, and performance under high pressure.

Even in environments with extremely high corrosion levels, stainless steel ball valves are a durable option; 316 stainless steel is a specificallycorrosion-resistant alternative that contains molybdenum—a silvery metal with an exceptionally high melting point—in addition to nickel, which is more than that of standard stainless steel. 

Brass, an alloy of copper, zinc, and occasionally additional metals, can also be utilized in ball valve manufacturing. Brass ball valves may contain trace quantities of lead, typically below 2%. The approval of certified lead-free brass ball valves is limited by the Federal Drug Administration (FDA) in light of the potential health hazards associated with lead.

Flexible sealing is the initial component to malfunction in a metal ball valve. This means a brass ball valve last as a stainless steel ball valve prior failing in most applications. In conditions where a corrosion-resistant metal is not a prerequisite, brass will provide equivalent durability to stainless steel. Numerous applications, including residential and commercial structures, water wells, and HVAC, use brass ball valves extensively. F.D.A. regulations require that certified lead-free brass ball valves be used in specific applications, including food processing or potable water.

Replacing the ball valve on the heating pipes

Cost Effectiveness 

A cost advantage distinguishing brass ball valves from stainless steel is their cost-effectiveness. Due to its generally lower cost than stainless steel, brass is frequently used in plumbing applications. Furthermore, the production of brass ball valves is considerably less complex than that of stainless steel valves, resulting in reduced expenses and ultimately rendering them more cost-effective. Brass ball valves are optimal for those who wish to save money without sacrificing quality or durability due to this benefit.

Corrosion Resistance

Due to their exceptional corrosion resistance, brass ball valves are ideal for use in severe environments. Unlike stainless steel, Brass is resistant to corrosion and corrosive and basic substances. This corrosion resistance extends the life of brass ball valves, eliminating the need for routine maintenance or replacement. Ultimately, this benefit results in increased value for the investment made.

Heat Resistance

Also, brass ball valves are more heat-resistant than their stainless steel counterparts. Increased temperatures do not cause the brass to deform, contort, or fracture. They can enhance performance and durability, which makes them an ideal material for applications requiring thermal resistance, such as hot water systems.


Additionally, brass ball valves are adaptable and can be implemented in various industries and applications. In addition to many other applications, they are utilized in plumbing, HVAC, industrial apparatus, and fire suppression systems. Their sturdy construction and dependability make them the preferred option for numerous industry experts.

Ease of Installation

Another benefit of brass ball valves is that installation is straightforward. Most brass ball valves are characteristically two-way and feature threads facilitating their installation into the plumbing system. Furthermore, the substance exhibits great versatility, facilitating plumbers to trim, deform, or reshape it to conform to precise installation specifications.

Applications For Stainless Steel Ball Valves:

Due to their resistance to corrosion, high temperatures, and high pressures, stainless steel ball valves find widespread application in construction, manufacturing, and industrial processes. The following are some of the most prevalent uses for stainless steel ball valves:

Petroleum refining

Marine operations

Brewing systems

Brass ball valves are comparable in efficiency and durability to stainless steel ball valves in most applications. In applications requiring extremely high temperatures or pressures, stainless steel or other materials with enhanced durability may be more suitable. However, the flexible seals commonly constructed from P.T.F.E. will remain the most vulnerable component. This requires the use of specialized barrier materials in these extreme applications

Factors to Consider While Buying The Ball Valve

When purchasing a ball valve, there are several factors and concerns that you need to keep in mind to ensure that you’re getting the right product for your needs. Here are some critical considerations

Temperature Range

Assess the pressure and temperature range that the application supports. Ensure that the valve’s temperature endurance corresponds to your system’s operating temperature.

End Connections

Compatibility with the conduit system and suitability for installation consideration of the end connection type. Threaded, socket weld and butt weld connections are all prevalent alternatives.

Raw Materials

When selecting a valve material, ensure it is compatible with the fluid being processed and the surrounding environment. Brass, stainless steel, carbon steel, PVC, and bronze are prevalent materials. Temperature restrictions, corrosion resistance, and chemical compatibility are all factors to consider.

Flow Characteristics

Consider the flow features of the application. A complete port ball valve may be more suitable if you want to reduce pressure loss in applications requiring high flow rates. Cost-effective reduced port ball valves may be utilized when the flow rate is not of the essence.

Difference Between Ball Valves and Globe Valves

Globe Valves and Ball Valves are two prevalent types of valves that find application in a wide range of situations. Every individual possesses distinct qualities and is more suitable for particular tasks. A comparison between the two is as follows:

Valve Design:

Globe valve design: There are three fundamental configurations of globe valves: T- or Z-globe valve, Y-globe valve, and angle globe valve. Consult our article on globe valves for detailed descriptions of each variety.

Ball valve design: Various classifications of ball valves are possible on the basis of the housing structure, ball design, and port size. Depending on the structure of the enclosure, ball valves may consist of one, two, or three pieces. Ball valves are classified as reduced port ball valves, standard port ball valves, or complete port ball valves, according to the extent of the port. Further, the number of ports determines the classification of ball valves into two-way or multi-port valves.

Flow Control

Both globe and ball valves function to regulate the passage of fluid. However, they can also operate in a partially closed or open state in order to regulate the flow rate. This flow regulation is possible because the disc of the globe valve is positioned in parallel with the flow. Globe valves attain a greater linear flow rate than ball valves, thereby minimizing the impacts of water pressure.


Globe valves are utilized for fluid flow regulation. In addition, globe valves offer distinct benefits in scenarios that necessitate accurate throttle regulation. In contrast, ball valves are frequently employed to isolate and turn off plumbing systems. Fuel oil and cooling water systems are industrial applications for globe valves, whereas the chemical storage and natural gas industries utilize ball valves.

From Core Engineering

What Are the Best Ways to Assess the Quality of Ball Valve?

If you want your ball valve to last and work correctly, you need to choose one of high quality. To ensure a ball valve is of high quality, you must follow these steps:

water pressure checks

Inspection by Sight:

First things first, have a look at the ball valve. Check the outside of the valve for obvious flaws or irregularities. Verify that there are no obvious signs of damage or distortion on the body, ball, stem, and seats.

Evaluating Dimensions:

Take careful measurements of the valve’s diameter, length, and thickness to ensure it meets all requirements.

Analyzing the Materials:

Verify that the material listed for the valve is accurate. Techniques such as spectroscopic analysis may be used to analyze materials.

Pressure Testing:

Testing under pressure is essential. To ensure that the valve can withstand pressure without leaking, it is typically closed and pressured on one side. The next step is to gradually let off pressure while checking for stem or seat leaks. Suitable methods for this kind of testing include API 598 and ISO 5208.

Functionality Test:

It is also crucial to carry out a functionality test. To ensure everything works smoothly, open and shut the valve many times. Before operating the valve at its maximum working pressure, be sure it can be turned effectively.

Non-Destructive Testing:

Dye penetrant inspection (D.P.I.), magnetic particle inspection (M.P.I.), ultrasonic testing (U.T.), and radiographic testing (R.T.) are all examples of non-destructive testing (NDT) techniques that may be used to find interior flaws, depending on the application.


As a general rule, testing should only be carried out by qualified individuals by established methods and standards. Since various valves may need distinct testing protocols, you must always consult the ball valve manufacturer’s guidelines.


Choosing an experienced supplier is crucial. Ball valve suppliers who have been around for a while have shown they can handle industry ups and downs and always provide what their customers need. 

Treatment of Material:The way in which raw materials, such as brass, stainless steel, or any other metal, are handled may have an impact on their performance, in addition to the sourcing process. Processes like alloying or even unique treatments may be used to increase the lifetime and durability of materials.

Standards and Product Quality:We will not compromise on quality. Ensure the ball valve supplier’s products are certified and up to industry requirements. Quality assurance procedures and material selection influence valve performance

Technical Support and Customization:Solutions tailored to your specific operating demands may be necessary. To ensure the valves fit your needs, look for a source offering technical assistance and customization options.

Exploring Potential Wholesalers:

Look online first and Inspect the supplier’s website, read reviews, and check ratings. You may learn a lot about a supplier’s strengths and shortcomings from customer interactions.Communicate and inquire with prospective vendors face-to-face. Get to know their offerings, services, and personalization choices. Customer happiness is their priority, so they communicate quickly and clearly.

Learning About Price Structures: Evaluate price quotations from various vendors. Prices that look too low should raise red flags. Get a feel for the price system, and make sure you ask about any hidden fees.

Assessing Supplementary Service Options: Think about adding value with services like maintenance, technical support, and post-purchase help. These services improve things in the long run and improve the whole thing.

Fame on a Global Scale: It’s not enough to have qualifications; these certifications must be recognized globally. Marks such as ISO, ANSI, or C.E. are trusted by people worldwide and are easily recognizable. Certifications emphasizing safety standards are particularly important for valves intended for critical applications. Inspect their commitment to safety by looking at their safety milestones, any violations, and the steps they take to fix them.

Understand what the ball valve supplier’s testing protocols are. We guarantee the valves’ dependability under diverse situations by thoroughly testing them, including pressure and leakage tests. To keep projects on schedule, logistics, and timely delivery are of the utmost importance. For on-time order delivery, inquire about the supplier’s shipping and delivery procedures.

Research and development priorities: Technological If a provider spent a lot of money into R&D, they want to be the first to market with new technologies.

Key Factors When Choosing a Ball Valve Supplier

Ball valves play an integral role in managing the flow of fluids in various industrial and residential applications. It’s crucial to find a reliable ball valve supplier to ensure consistent quality and safety. 

ball gas valve applications

The Common Pitfalls While Purchasing Ball Valve

To mitigate these risks, emphasize Ball valve quality control, ensuring that your supplier is dedicated to maintaining consistent and reliable products. Additionally, prioritize Ball valve standards compliance to guarantee that your valves adhere to the industry’s necessary safety and performance requirements. 

The Materials for Manufacturing of Ball Valve


Brass is priced higher. Because brass is more resistant to heat than plastic, brass ball valves are an excellent option for residential plumbing applications. Brass is considerably more malleable than stainless steel and can be easily welded. Lead is occasionally added to brass (usually in concentrations below 2%); therefore, opt for a lead-free variant for ball valve applications involving potable water. Brass exhibits superior resistance to corrosion in comparison to bronze and cast iron. Brass may deteriorate when exposed to excessive concentrations of chlorine.


Bronze is an alloy consist of tin and copper, a durable and malleable material that resists rapid cracking. Bronze components are produced by casting the material into a mold or constructing a pre-cast bronze ingot. Small holes are present on the surface of bronze, which imparts a realistic, porous appearance due to the casting process. With specific additives, bronze alloys can retain a polished surface. Bronze has numerous advantages, including low cost (compared to brass), high flexibility (resistance to splitting), and corrosion resistance.

Stainless steel

Applications involving high temperatures and pressures are well-suited for the extremely resilient and long-lasting stainless steel. In contrast to brass, stainless steel exhibits superior resistance to corrosion and leakage. Due to its exceptional chloride resistance, ball valves constructed from stainless steel 316 are suitable for marine environments. One of the significant advantages of stainless steel, particularly in applications involving food processing, water systems.

WCB steel

A WCB ball valve is an industrial valve constructed from “Weldable Cast Carbon” steel of the “B” grade, known for its significant durability and robustness. The term ‘ball valve’ comes from its internal mechanism – a spherical ball with a central bore that controls the flow of substances, typically liquids or gases. When the bore is aligned with the pipeline, the valve is open, allowing passage, and when perpendicular, it’s closed, blocking flow.

What Is A PVC Ball Valve?

A PVC ball valve is an on/off plastic valve with a rotary ball featuring a bore. The fluid flow can be halted by rotating the ball by a quarter turn. They are cost-effective, extremely durable, and capable of regulating the passage of acids, bases, water, oxygen, and corrosive compounds. Despite their diminished mechanical strength, P.V.C. ball valves are exceptionally resistant to low pressure and temperature. Like all other ball valves, P.V.C. ball valves halt the flow by rotating a ball by 90 degrees.

P.V.C. ball valves are composed of a rotating component called a rotary ball. Depending on the design of the valve, the mechanism for rotating the ball, which consists of a stem at its apex, can be either manual or automatic. When the handle is parallel to the line, the valve is open; conversely, the valve is fully shut-off when the handle is perpendicular to the pipe.

Ball valves made of P.V.C., which is fireproof plastic, can withstand temperatures between -14 °C and -140 °C. They are adaptable to various applications, have a lightweight body, and a compact structure; they also serve many of the same functions as conventional ball valves. Generally exhibit optimal performance within the temperature range of 33°F to 140°F (0.5°C to 60°C). Although P.V.C. can endure lower temperatures, its brittleness significantly escalates, resulting in fracture or failure. Also, elevated temperatures can induce deformation and softening in P.V.C., compromising the structural integrity of the valve.

Bore Structure

While the two-way PVC valve is the most prevalent, alternative bore designs can potentially enhance the performance of a given application. Three-way bore designs incorporate T port and L port configurations, which prove advantageous in fluid flow mingling, distribution, and diversion scenarios. These bore designs can be extremely beneficial when dealing with various fluids and flow types.


Method to Control:

When fluid streams in the desired direction, the valve is opened; conversely, backflow causes the valve to close. Weight, back pressure, a spring, or a combination of these elements all function to prevent backflow through the check mechanism. Additionally, the term “disc” is commonly employed to denote the mechanism, whereas “ball” and “poppet” are also utilized. The disc in the form of a ball comprises the closure component of the ball valve. With a quarter-turn of the actuator, the valve is unlocked. To facilitate the passage of the media through the valve, the turn ensures that the ball’s opening is in a parallel alignment with the flow. Upon closing the valve, the ball rotates vertically to the flow, obstructing the media’s passage.


Metallic and non-metallic materials can be utilized in the construction of check valves. Exterior coverings are frequently constructed from plastic or metal. The most commonly used material for check valves is corrosion-resistant stainless steel, although carbon steel and forged carbon steel are also employed.  Body components may be constructed from any of the following materials: brass, titanium, bronze, stainless steel, chromium, P.V.C., and C.P.V.C. Additionally, ball valves incorporate a wide variety of seats and seals. The suitability of substances for specific purposes is determined by chemical compatibility, temperature, and pressure.


The media is essential when determining the type and pace of the actuator, in addition to the material for the valve body and disc. Materials for the valve system could be extremely diverse.Ball valves exhibit exceptional performance with both gaseous and liquid media. This valve design can be applied to challenging substances such as oxygen, hydrofluoric acid, anhydrous chlorine, and hydrochloric acid. The slurry solidifies in the cavities enclosing the ball and seats, which diminishes the effectiveness of the slurry transfer. Increased operating torque may result in valve damage. Most ball valve manufacturers recommend that trace particles not exceed 3%.

Ball Valve Vs. Check Valve

By understanding these differences, customers can make more informed decisions about which valve type is best suited for their specific needs, whether they’re managing straightforward flow control with ball valves or preventing backflow with check valves.

Check Valve Applications 

Check valves serve the purpose of preventing backflow and maintaining pressure. They are commonly utilized as a contingency measure when the system pressure exceeds the capacity of the central gap or when a pump malfunctions. Various industries require check valves, including oilfield production, chemical, petrochemical, water, steam, and petroleum refinement. Ball valves have widespread applications in fire safety protection services, chlorine producers, and circulating systems aboard ships. Due to their challenging cleaning properties, these materials are contraindicated for use in bioprocessing, food and beverage, and pharmaceutical applications.


Swing valves, lift valves, ball valves, double-disc or wafer check valves, umbrella valves, butterfly valves, cartridge/manifold valves, foot valves, poppet valves, and pivoting disk check valves are the various types of check valves. Among the various varieties of ball valves are welded valves, single body valves, three-piece body valves, split body valves, top entry valves, and reduced port valves, as well as full port valves and v-port control valves.

The FAQs About Ball Valves

Please note that are common questions from most customers. Could you please feel free to contact us if any further questions or are confused about ball valves?

Typically, soft-seal ball valves are not employed in modulating service applications due to the susceptibility of the valve seats to attrition or displacement during periods of partial opening or closing.

Long lifespan and reliable sealing are characteristics of ball valves, even when the valve is inactive for an extended period. As a result, ball valves are more prevalent in piping systems compared to alternative shut-off valves like gate valves, which exhibit a significantly longer operating time and are more susceptible to leakage.

The diameter of the ports on a complete port ball valve is equivalent to that of the connecting pipelines. The pipe diameter is greater than the valve port size in a standard port ball valve.

In general, ball valves do not necessitate many maintenance interventions. They have straightforward flow regulation mechanisms and a reduced failure rate. Nonetheless, this does not eliminate the possibility that industrial valves will eventually necessitate maintenance. When selecting valves, devise an inspection and maintenance strategy. The maintenance requirements for manual ball valves may be lower than for actuated valves.

Numerous circumstances may necessitate the purchase of a ball valve. You may be in the process of installing a new washbasin for a kitchen renovation, or you may be a plumber in need of replacing an old ball valve. We provide an extensive selection of reasonably priced, high-quality ball valves to ensure you can locate the ideal one for your requirements. 

Ball valves are one of the most important components in a plumbing system. They allow for easy flow control and can even be used as shut-off valves during emergencies. However, there is a lot more to them than meets the eye. The size of your ball valve will depend on the amount of pressure you need it to withstand, but generally speaking, they come in a few different sizes:1/4",3/8",1/2".3/4",1",1-1/4",1-1/2" 2", 3" and 4",6" and 8."

Different ball valves have different sizes, and the valve you need will depend on how much water is going through it. For example, you're looking for a small valve that can fit into tight spaces like plumbing under sinks or in bathroom cabinets. 

A ball valve is open when its handle is parallel to the conduit and in the closed position when it is perpendicular. Visually determining whether a ball valve is closed or open is simplified.

It is possible to install the ball valve upside down; however, any orientation other than vertical represents a compromise. The inverted installation method is not advised.

Most of the time, high-pressure ball valves are used as the main input. Near the tank, there is a lot of fluid under a lot of pressure that wants to come out, but a high-pressure ball valve can stop it. A low-pressure ball valve is used in toilets and other places.
