Check valves are retention or non-return valves. They maintain flow regulation via a single path, thus preventing backflow. This means your check valve can allow the incoming fluid to follow the path at the outlet. But it doesn’t let it flow backward. This retention of fluid is often considered of great significance in many systems. It saves the medium from getting pollutants or other unwanted elements in the stream. The port from where fluid enters is the inlet, while the other one that takes it outside is called the outlet.
The check valves have a principle that operates depending on the pressure changes. When the inlet pressure is higher, the valve opens up. It creates the passage for flow to reach across the other end and exit the valve body. On the other hand, when the pressure at the outlet is high, the valve restricts the flow and shuts down the supply. The symbol of check valves indicates this mechanism very well. It has two horizontal lines standing for two ports. The triangle and a vertical line state that one-sided flow and non-return work.
Check valves are the simplest yet essential plumbing fixture. Its design and functioning contribute much to the overall performance. We can analyze the importance of checking valves from these two inevitable factors.
Safeguarding Fluid System:
We cannot deny the significance of check valves in adding safety to the system. They work more like a safety valve due to their sophisticated job. Backflow prevention is central to keeping the system upright. If we ignore check valve installation at chief locations, it may lead to system failure. They regulate the pressure and serve as a safety shield for the overall system.
Ensuring System Integrity:
Check valves compliment the performance of the system, which maintains its integrity. Suppose you have a residential check valve installed in your house. In that case, you need not worry about sudden pressure spikes or contamination of potable water. They keep checking on these facts, which leads to an efficient plumbing system. Their working process keenly focuses on protecting the pipelines and other fixtures.
The working mechanism of check valves leads to two kinds of operations. It includes opening the inlet and closing the outlet port. The valve opens when the coming fluid exerts pressure on the blocking element. This is the difference between the pressure on the inlet and outlet ports. On overcoming this pressure, the valve opens. It causes the ball to rotate or the diaphragm to slide away, creating a linear path for fluid to pass across. The valve is in the open position and continues its flow as long as the reverse action occurs.
Similarly, the inlet pressure decreases to outlet one when the situation changes. It causes the check valve to shut off. This process occurs when the fluid, once passed from the outlet, tries to re-enter via backflow. It creates a quick and efficient shut-off to prevent flow from returning to the valve body. The blocking elements in check valves differ depending on their adaptability and applications. Popular ones are balls, discs, and diaphragms. The actuation method may also vary in check valves. It can be manual, electric, pneumatic, or hydraulic control methods. Each one is easy to operate in specific environments.
Check valves have distinct working pressures. The difference usually lies in their types and different check valve manufacturers. Here are some standard ratings generally found in specific industries. | |
● Oil, Gas, and Water Applications ● Cold Pressure Working ● Pressure Nominal (PN) | They usually have a nominal pressure rating at room temperature. These valves have working pressure between -20F to 100F. These are standard ratings offered by some check valve manufacturers. |
Check valves are quintessential products to prevent systems from blocking as a result of backflow. Each system demands relatively different working conditions. Similarly, there are various modified designs of check valves for each requirement. The main difference in their type often lies in the type of blocking element. Here is an analysis of the different types of check valves and their working phenomenon.
As the name suggests, these check valves employ a spring-loaded mechanism. This product ensures long-term service due to its durable structure. The inlet pressure should be high enough for the valve opening to overcome the spring force. When this goal arrives, the passage is clear, and fluid rushes out. To close the valve, the inlet pressure should drop. It causes the disc to shut the valve using spring force. The ideal quality of spring inline check valves is their ability to handle water hammers. They can undergo several pressure changes with quick operations.
Swing check valves are among the top check valve types in the market. It is favored due to the adaptation of the swing’s robust mechanism. The end connections are mostly flanges but may vary depending on the design. They use a disc or flapper connected to a shaft instead of the regular ball. Upon an increase in inlet pressure, the swing mechanism activates. It removes the disc from the valve seat, allowing fluid to escape. The disc or flapper returns when pressure decreases, creating a seal. Swing check valve manufacturers produce valves with the least flow restriction when open.
Lift check valves work on a different principle than swing or spring valves. The movement of the disc appears like that of a piston. Thus, it is also called a piston check valve. The internal construction of this product is quite like that of globe valves. The disc often mounts a small spring to smooth operation. When the internal pressure overcomes gravity, the disc lifts vertically from the seat. It allows water passage and blocks the chances of contamination due to backflow. Yet, for each direction, the valve needs a quarter rotation to turn to change the flow state.
These types of check valves have significant strength and pressure-handling capacity. They have dual plates with powerful yet manageable working. The best adaptation of these check valves is to handle huge flow capacity. Thus, they are usually installed in industrial settings to control streams of fluids. Their design and structure are compact. It takes less space than other industrial check valves. Their lightweight makes them easy to deliver globally and makes installation easy. This check valve type works like usual ones based on pressure differences.
The diaphragm check valves can have a diaphragm either free-floating or fixed flexing. The mechanism varies for each of the types. In this case, the blocking element is a diaphragm, which brings out the change in the state of the valve. When there is a free-floating diaphragm, no cracking pressure is required. Instead, it freely moves away on the arrival of fluid and closes on its departure, preventing backflow. A fixed diaphragm must have a pressure difference between inlet and outlet pots. Both cases refuse the entry of fluid back to the system via outlet. It is ensured via a tight seal.
Wafer check valves are a sleek adaptation that fits between the flanges in a pipeline. Within these valves lie wafer-style discs. The movement of these discs brings change in the system by either allowing fluid flow or blocking it. They provide seamless integration in a system due to their compact structure. The discs swing from their position when the actuator is turned. This disc connects with the hinge, which causes the valve to open or close. Due to its high demand, industrial check valve manufacturers produce bulk quantities of this product. They are widely applicable in multiple settings and conditions.
Ball check valves are among the top check valve types. Their easy mechanism makes them a suitable choice for almost every application. Besides, they are popular among check valve manufacturers due to their high industry demand. A spherical ball is a blocking element that opens or closes the valve. Their structure enables unidirectional flow. Thus, when the fluid enters via the inlet, it pushes the ball away from the seat to clear the passage. Similarly, the ball blocks the path of the fluid and tries to re-enter the system from the outlet. It prevents contaminations and backflow malfunctions.
One of the devastating problems in fluid control systems is water hammering. The main reason for this is the excessive pressure built up in the valve. Non-slam check valves are an excellent option for dealing with dynamic pressure changes. They have a particular structure that can withstand and avoid these situations priorly. An internal spring is connected to the disc, compressing the valve opening. When the pressure decreases within the valve body, the spring causes the disc to return to its position. The closure of the valve is a soft mechanism to prevent hammering. This effective mechanism also saves from vibrations and pressure spikes.
Stop-check valves are efficient and dual-functioning check valves. As the name suggests, one of their functions is to prevent the reversal of flow direction. The second function they perform is as a shut-off valve or throttling. Stop-check valves have a high level of endurance to activate and work simultaneously without jamming or blocking. They have a usual actuator on the valve top to manage and restrict flow. Turning from the initial position brings a state change. Tolerance for backflow is negligible as they have a quick and efficient mechanism. Their common usage is in residential and steam applications.
Tilting discs are an innovative addition to the check valve family. Their pivot point is in the center of the disc. It allows fluid to move at the bottom and above the disc. The disc is often spring-loaded, which causes it to show a quick mechanism. This structure enables the valve to deal with frequent flow reversals. The valve can open even at low fluid pressure with a robust closure. Tilting disc check valves can manage high flow capacity due to floating disc within. Their common usage is in sewage systems and firefighting applications. These valves are ideal for transporting liquids and gaseous media.
Residential check valves serve the household requirements of plumbing systems. They are of essential value to maintain your system and save you from backflow hazards. Plumberstar acknowledges your demands for reliable check valve solutions. Our professionals are very concerned about your health as they carry potable water. We provide you with an exclusive range of affordable check valves without compromise. Here are the top applications for check valves by Plumberstar-Valves manufacturer.
Potable Water Systems:
The residential check valve applications involve carrying potable water. These valves maintain the integrity of drinking water. They keep water separate from other streams and prevent contamination and backflow. The installation of check valves in such conditions not only keeps the water safe to drink but also effectively regulates its flow.
Water Pumps:
Water pumps undergo frequent pressure changes. That’s why they are prone to hammering effects and blockages. Check valves in these pumps relieve these hazards by regulating pressure and preventing backflow. They keep water moving until the air expels from the pump, which otherwise cannot be done by the pump itself.
HVAC Systems:
HVAC systems in homes or residential buildings are among the top applications of check valves. They require a coolant to be pumped up at height. Check valves are significant in bringing it by resisting the force of gravity. They also ensure that no fluid mixes up with another stream or back-flows to the primary system.
Irrigation Systems:
Brass check valves in irrigation systems perform significant functions. As irrigation involves water dispersal into many streams, check valves suit the system’s needs. They take water to the desired destination along with a safety mechanism. They ensure backflow prevention to the main supply and stop contamination from damaging the equipment or water quality.
Liquid Fuel Systems:
Liquid fuels include hydraulic, synthetic, jet, and compressed air. Check valves in these systems have a unique design that provides stable operation from opening to allowing maximum flow. The function of backflow prevention is of substantial importance. If not checked, the backflow can lead to system failure and pose a personal threat.
Check Valve Size Instructions | ||
● The fluid capacity highly depends on the size of the check valve body and openings. The effective operation of the check valve can be achieved by selecting a suitable size. It also helps determine where a specific size can fit perfectly. ● The most compatible way of choosing a size is by comparing it with the application. If you need more clarification about the application requirements, ask the top check valve manufacturers for an accurate estimate. ● Keep specific facts in observation while finalizing check valve size. These include pressure, temperature rating, flow characteristics, and fluid viscosity. | Valve Sizes: 1/8 Inch: 1/4, 3/8 Inch: 1/2″, 3/4″ :1″:1-1/2″, 2″:2-1/2″, 3″, 4″ In household appliances like washing machines. In Large residential systems. In commercial plumbing systems. Common in industrial applications. 6 Inches and Above: Municipal water control systems. | Thread Sizes: Some standard thread sizes in check valves are the following: 1/2 inch (12.7mm), 0.59 inches (15mm), 3/4 inch (19.05mm), 1.5 inches (38.1mm), 2 inches (50.8mm) |
Backflow Prevention:
Backflow in many systems can seriously threaten equipment and media streams. Check valves to cover this malfunction with the help of a robust action mechanism. They do not let any media or fluid contamination reach back to the valve body. This means that they offer unidirectional and streamlined flow.
Pressure Regulation:
Pressure regulation is another prominent function of a check valve. They keep the pressure at an optimal level throughout the valve body. Prevention of backflow and smooth, fluid passage is the key to regulating pressure. This leads to efficient and seamless equipment operation like regulators or pumps.
Low Water Hammer:
Water hammers commonly malfunction due to sudden pressure changes. This severe issue can damage the pipelines and cause system failure. Check valves frequently reduce pressure spikes and block fluid from flowing back. It helps deal with water hammering and reduces the risks.
Equipment Protection:
Despite their backflow prevention feature, check valves contribute significantly to equipment protection. The flow reversal can lead to severe hazards affecting the valve body and the system. Check the valve safety mechanism to avoid contaminants causing buildups or damaging the delicate parts. It adds to the performance and longevity of the system.
Check valve functions, including the characteristics they offer within a system. These are among the most efficient regulating valves. Check valve applications are extended through multiple domains and fields. Here is a list of check valves’ primary functions, highlighting their role.

● AWW Standards: C508, C510 ● API Standards: API Std 594, API spec 6D ● BSI Standards: 5352, 5160, 5154, 5153, 5152, 2080, 1873, 1868 ● ASME Standards: B16.34 ● MSS Standards: SP-42, SP-61, SP-71, SP-80, SP-84 |
Check valve manufacturing covers many different designs, including the material selection. Check valve manufacturers have grown enormously over time. This has created a massive range of valves available in various material options. However, not every material is suitable under specific conditions. Plumberstar has prepared a list of the best materials for check valve manufacturing. It will take away your doubts and ambiguities regarding the most suitable material.
Brass is an excellent choice for manufacturing check valves immune to corrosion. It is wear-resistant and appropriate for controlling water as a medium. Brass check valve applications regulate water, oil, fuel, and gasses. They are ideal in residential settings with low-pressure requirements.
Stainless steel is a robust material for check valve construction. It is resistant to corrosion and can withstand considerable temperature levels. Stainless steel check valves have a well-composed structure. They are suitable for a moderate range of media and flow capacity. However, this material is more expensive than brass.
Bronze is a sophisticated and old material in OEM valve manufacturing. It offers many advantages over cheap and incapable materials. Bronze check valves are feasible for applications demanding medium or low-pressure requirements. They can fit in complex systems due to corrosion resistance and rigid construction.
As a construction material, PVC has a rare chance of catching corrosion. Thus, check valve manufacturers use PVC for specific applications with the least possibility of corroding. A particular category of these check valves can be used in acidic mediums. Yet, they have a limitation of deteriorating when exposed to chlorinated media or temperatures above 60°C.
Polypropylene is among the best check valve manufacturing materials. They also have remarkable corrosion resistance. They have a distinctive feature of withstanding essential solutions and inorganic acids, which adds to their diversity. The maximum temperature limit for polypropylene valves is 80°C. Typical applications include water supply systems and food industries.
Y-strainer check valves are often placed with check valves. They assist in checking valves with their filtration mechanism. Their y-shape offers much convenient working and functionality. These valves have a mechanism for pre-filtration or debris removal. They employ screens with different mesh to filter the media. It saves the system from wearing out and increases the lifespan performance. They can be spring-loaded, where the spring provides enough force to shut or open the valve. They usually take up more space than regular inline valves. The most favorable approach for these valves is their ease of maintenance due to self-cleaning. We can service the valve without even disassembling it or stopping the flow.
The working of a y-strainer is often straightforward. Yet, it highly depends on your selection of y-strainer manufacturers. A credible manufacturer like Plumberstar will be sufficient to provide desirable valves that stand the test of time and are also cost-efficient. Y-strainers are common in steam and liquid chambers. When the flow reaches the valve, the screen in the filter obstructs it and collects all the debris. This hindrance drops the pressure of flowing media and also removes impurities. A draining plug with dual metal plates keeps filtered and unfiltered media separate.
The Y-strainer has mesh, which further catches impurities from the liquid. These waste materials are prevented from polluting the mainstream. Similarly, they also ensure that no pollutants flow back to damage the equipment or system. These valves are capable of withstanding high fluid pressure and velocity. The modes of connection differ greatly based on material selection. The most popular types of y-strainers are cast iron, stainless steel, bronze, and iron. This is how a y-strainer works to maintain the flowing media’s integrity and purity.
Y-strainers offer a range of benefits to the system’s performance. Yet, there could be a mismatch between the product specifications and the application demand. It may result in the cons of the y-strainers. Here is a brief analysis.
Pros of Y-strainers | Cons of Y-strainers |
Y-strainers can be installed horizontally or vertically. They fit with the varying installation demands. Unlike other filters, we can install only in one direction. | Due to screens of a specific limited size, it may be hard for these strainers to manage high contamination levels in fluids. |
The working mechanism of y-strainer makes them ideal in high-pressure conditions. This is due to their robust construction. | Y-strainer cleaning can interrupt the overall system. They do not have options for separate cleaning, like basket strainers. |
They have significantly fewer maintenance requirements, making working over a long period possible. | If there are frequent changes in flow direction, it can cause pressure drops in the system. |
The price of the y-strainer is lower than that of other filtration strainers. Their minimalist design cuts off high expenses. |
Y-strainer manufacturers consider certain materials in the manufacturing process. These include bronze, stainless steel, cast iron, ductile iron, and PVC. Stainless steel has the highest pressure and temperature range, while brass is the most durable. Cast iron provides regular pressure and temperature limits, while PVC is suitable under varying conditions.
Y-strainers have an effortless maintenance mechanism. They are built to function for longer spans without needing frequent maintenance. However, there must be a few considerations when dealing with this product. Clogging can be a performance-deteriorating problem that affects the integrity of the system. Thus, following a few general instructions for maintaining a y-strainer is advisory.
One of the common shortcomings in y-strainers is the occurrence of pressure spikes. It can be a product affecting malfunction. Installing a pressure gauge can be a good initiative in maintaining a y-strainer. It can monitor the pressure of your system and update you for any pending pressure relief.
While blocking contaminants, the screen within the y-strainer may get clogged. They need regular cleaning, which involves taking them out and removing all the accumulations. You can keep extra screens to cut down maintenance time to save your maintenance time. Take out the dirty one, clean it some other time, and place the spare one in its place.
High pressures usually disturb the cleaning mechanism of y-type strainers. Before opening up the strainer for cleaning, ensure significantly low pressure. In case of elevated pressure, there can be a risk for personnel. It may also lead to potential damage within the valve assembly.
For residential strainers, the flow capacity must match the size of the product. The y-type strainer fails to perform its performance at a high flow rate. Excessive pressure can lead to damage to the screen and rupturing of the body. Alternatively, you can opt for a giant-sized valve to meet the demands.
You can conduct pressure tests after regular maintenance activities. They increase the life span of the y-type strainer. It also reveals the sealing capacity and response time of the strainer. From the paths closed, slowly release the water supply and observe the overall working of the y-strainer.
Specific tests are essential for brass check valve manufacturers. Based on these tests, they comply with the market standards and get credibility. They validate a product that can keep the system safe and save it from potential hazards. Plumberstar, among the best check valve suppliers, focuses on running these tests. They are equally essential for the buyer to perform these and determine the integrity of products. Here are the standard inspection tests for check valves followed for reliable check valve solutions.
Visual Inspection Test:
It is the most basic check valve inspection test to qualify for the API 570 standard. It includes visually examining the valve, its components, and the pipeline components. Remove the bonnet and body cover to examine the internal components. Next, the valve can be inspected for corrosion, wear, and missing parts (if any). The necessary checking, however, involves the flapper inspections to see if it is moving freely or not. There should be no wear on the flapper bonnet as it can leave space, which may allow backflow in a vertical position. All the components should be fastened to the valve body, leaving no room for leakages.
Backflow Leak Test:
This test is a characteristic of the check valve inspection. It is commonly called a bubble test, which checks the valve’s backflow prevention capacity. The manufacturers perform this test by submerging the upstream side of the valve in water. Now, they apply air downstream of the check valve. The bubbles appear on the surface. They are counted and calculated as per the standard testing system. If the data matches the acceptance criteria, the product is said to pass the API 598 standard for the check valve industry. The bubble test reveals the resilient feature of stopping flow from entering the system from the outlet.
In-line Inspection Test:
Swing check valve manufacturers perform in-line inspection tests on the products. This type of test is less common than the inspection and bubble test. It includes examining pipelines and associated accessories. The aim is to measure deformity, cracks, and corrosion within the piping system. In-line testing demands a specific configuration of piping. They simulate reverse flow and check for the ratio of backflow upstream of the product. This test ensures relief from hazards of system failure and pipeline ruptures due to the inefficiency of the check valve. Hence, top check valve manufacturers are recognized for their tendency to conduct safety tests before releasing products.
Selecting check valves requires a great deal of careful analysis. The product must be resilient and compatible with your client’s business demands. Certain parameters can assist you in drawing an overview of considerations before buying. Our experts have short-listed some factors and prepared a check valve selection guide. It is a reliable option for you during the selection process.
Each of the check valve types can handle certain fluids. Therefore, it is necessary to estimate your fluid requirements for the system. Some valves are built to transport potable water, while others may carry sewage water. Ensure you know exactly what fluid your check valve is going to handle.
Pressure plays a central role in operating and closing the valve. While selecting check valves, you must consider the pressure ratings. Check if the fluid entering the valve can generate enough pressure to overcome cracking pressure. Similarly, check if it can seal the outlet once the fluid is out of the body.
The pipeline and connection type of the existing system are also important to consider. Check what thread connection suits your system and whether they are compatible with the valve type. The pipeline and its components also matter when installing a new product. Make sure all the elements sync for proper functioning.
Check valve material also compliments certain systems. Therefore, one must consider it when purchasing a wholesale business or retailing. For instance, brass check valves can be a handy option for potable water supply. Installing a bacteria-prone material for this purpose can be devastating. Thus, this check valve selection guide insists on suitable material selection.
The operating mechanism of a valve includes its operation within a specific environment. The conditions may consist of the temperature range and external pressure influence. Each valve has a different strength to endure such conditions. The operating mechanism may also differ. Ensure you match the compatibility with your desirous standards.
The design options in check valves are vast and offer better performance in relevant environments. Swing check valves, for instance, have a low-pressure loss and less cost. Spring inline valves have low cracking pressure. While lift check valves have automatic operation. Choosing a suitable design can add much to the working and life span of the product.

Check valves are an automatic solution to prevent backflow in a system. The advantage of check valves is that they require less maintenance. They protect equipment and surroundings from damage due to sudden pressure changes.
While installing a check valve, proper orientation is the first consideration. Give keen focus to the proper alignment of the valve and sealing mechanism. Right valve size and pipe diameter should also be considered. The final bolt tightening should be followed by testing for leaks.
Common check valve problems include operational failure and leakages. The reason may include debris accumulation near the seat. You can open, inspect, and clean the valve. It solves the problem in most of the cases. However, severe leaks and failures may require a replacement or expert advice.
The difference lies in their mechanism of action. Swing check valves have a disc swinging around a pivot. This movement of the disc allows for fluid movement across the valve. The lift check valves have a disc or lift with a lifting mechanism.
Check valves are special fixtures for preventing backflow. However, you can also try some other options. It includes using flow restrictors, globes, or isolation valves. However, check valves are more efficient and reliable than these replacements.
The components of a y-strainer include a body, cover, and drain plug. A mesh or screen is crucial for these strainers to catch contaminants. A blowdown valve or drain plug removes the debris from the valve.
Y-strainers are available in a wide range of sizes. They may be 1/4 inch to several inches in diameter. The size depends on the flow demands and pipe size.
Some Y-strainers offer this feature, while others may not. The blowdown valves may allow mesh cleaning without shutting the entire system. This enables the y-strainer to remain isolated and avoid disturbance in the overall system.
