Introduction to Electric Valve

An electric valve is a type of valve that opens and closes with the help of an electric motor. This variety of valves is ideally adapted for applications involving remote fluid control, such as aircraft deicing, agricultural irrigation, and automated fire suppression. Commonly used valve varieties include the ball, butterfly, and gate, all suitable for motorized applications. The motorized valve is also highly ideal in applications requiring incremental valve operation in response to system inputs. Manual valve actuation inputs are the only distinction between the two and their electric valve regarding internal fluid control mechanisms.

Valves are integral to fluid flow circuits in hydroelectric power generation systems and garden hoses. When valves are inaccessible or located in remote areas, are too large to open or close manually, or must operate during periods when facilities or installations are unmanned, valve actuation challenges. Using an electric valve provides a solution to these issues. Except for being powered by an electric motor, this type of valve operates precisely as a manual variety would. This category of valve is capable of being opened or closed remotely through the use of an automated system or an operator.

General Manufacturing Structure of Electric Valve

Electric actuators and valves built the majority of electric valves. In electrical installation, actuatorsare powered by electricity. The connecting form of the stem nut and the connecting disc’s flange size comprise the output shaft, which facilitates the vertical displacement of the valve stem. The stem can operate the electric ball valve by causing the gate to move in a linear direction, thus enabling the valve to be opened and closed.

A manual operation mechanism is incorporated into the valve. In the absence of a power supply, manual operation is possible to open and close the valve. The valve can be closed when the handwheel undergoes a clockwise rotation. It is opened when the pneumatic ball valve rotates in the opposite direction of cyclic motion.

The valve flange is constructed with a self-pressure sealing mechanism, and its sealing gasket is made of stainless steel metal, capable of withstanding 4500 pounds of high-pressure sealing. Reliance can be placed in the ball valve’s hermetic performance. A wedge single gate configuration is utilized for the gate. The construction of the valve is compact and diminutive.

The valve body is constructed using a forging and welding framework, effectively addressing the quality issues arising from casting defects, reducing waste generation, and enhancing product reliability. Applying gate and seat sealing materials to cobalt-based cemented carbide that has been affixed.

Manufacturing Components of Electric (motorized) Valve

When it comes to motorized(electric) valves, there are several common spare parts that you may need for maintenance or repairs. These include:

making actuator


The valve body is the valve assembly’s main structural component and primary pressure boundary. It acts as the seat against which the disc prevents fluid flow. It connects to the inlet and outlet piping via threaded, bolted, or welded connections and takes the bonnet via threaded, bolted, or welded coupling. Forging or casting valve bodies are machined to interface with the other components.


Another significant pressure boundary component is the valve bonnet. It supports the disc, packaging, yoke/actuator, and stem, in addition to furnishing the closure head for the body. Connected to the valve body via threaded, mounted, welded, or pressure-sealed connections, bonnets forged or cast. The connection between the bonnet and the valve body is a pressure boundary. Consequently, welds are classified as pressure boundary components. 


The pressure boundary is completed by the valve disc, which also offers the capability to obstruct the flow path. Despite the disc being seated and the discharge piping depressurized, the entire system pressure is exerted. Discs are hard-faced and cast or forged to impart favorable wear characteristics.

Valve yoke

The valve yoke supplies the actuator with structural support. It always remains outside the pressure boundary and is connected to the valve body or bonnet. The yoke responds to the thrust or torque that the actuator applies to the valve stem.


Seats or seat rings serve as the disc’s sealing surface. In some designs, seat rings are omitted, and the body is machined as the sealing surface. In alternative designs, forged seat rings are threaded or welded to the body as a seating surface. Hard-faced is a common practice on sealing surfaces to enhance their wear characteristics. Seat rings are not classified as pressure boundary components because the body’s wall thickness is adequate to withstand design pressure without their assistance.


The ball is located inside the valve body and has a hole through its center. It is connected to the valve stem, which in turn is operated by the actuator. When the actuator moves the stem, it rotates the ball to either align the hole with the flow path (opening the valve and allowing fluid to pass through) or to position the solid part of the ball to block the flow path (closing the valve and stopping the flow). The ball is typically made of durable materials like metal or plastic.


The actuator performs stem and disc assembly operations. Solenoid actuators, manual handwheels, manual levers, pneumatic actuators, or hydraulic actuators are all examples of actuators. Pressure boundary components do not include actuators, except specific hydraulically operated valves.


The stem of the valve converts the actuator’s motion to disc motion. Stems are forged and fastened to the disc via flexible joints or T-slots. The stem is held with a smooth surface finish in the area of the closure on valve designs that necessitate stem packaging or sealing to avert leakage. 

How Does Electric Valve Work?

Typically, electric actuators and valves connect electric valves, which transform into electric valves during installation. The electric actuator is powered by electric energy through the electric valve to accomplish the toggling and regulating functions of the valve. To achieve the objective of modulating or altering the medium within the pipeline. 

Motors are utilized to power electric valves. Adjustments can be made to the time required to execute the opening or closing action. Contrast with resist voltage shock. Electric valves operate at a higher switching frequency than solenoid valves, are typically employed in applications involving minimal flow and pressure, and have rapid opening and closing. The regulation of the electric valve’s release is possible. The valve’s states are half-off, on, and off. The solenoid valve cannot fulfill the requirement of controlling the passage of the medium in the pipeline. Three-way electric valves consist of three lines labeled F/R/N:

  • F denotes the open action (forward action) control line.
  • R signifies the close action (reverse action) control line.

A solenoid valve is classified as an electric valve; it pulls the valve core with the magnetic field generated by an electromagnetic coil, thereby modifying the valve body’s on/off state. In the absence of a coil, the valve core is reliant on the spring pressure to function. 

Applications of Electric Valves

Industrial Processes:

Electric valves are frequently used in industrial settings, particularly in manufacturing, water treatment, and chemical processing, requiring precise and automated fluid flow regulation.

HVAC System:

Electric valves are frequently employed in heating, ventilation, and air conditioning systems to regulate the passage of refrigerant or air precisely, thereby enhancing energy efficiency and temperature regulation.

Water Management:

Electric valves are paramount in water treatment and distribution systems as they regulate the water flow to various zones, assuring optimized pressure management and distribution.

Process Systems

Manufacturing Process of Electric Valves

This procedure has phases: order and design, inventory, checklist, product process, assembly, testing, and inspection. Once a consumer orders, the manufacturing department will search for and procure primary materials. All the stages require a substantial amount of time to complete. However, this procedure is straightforward and will provide you with a more comprehensive understanding of the manufacturing process of industrial valves.

The valve manufacturing process entails the fabrication of valves of superior quality. This requires the use of handcrafted elements. After the consumer has approved the design of a valve, the subsequent step is to initiate the procurement process for it. The provider orders the approved design and receives a predetermined deposit.The manufacturing department begins procuring materials and raw materials as soon as the order is submitted.

The procurement of basic materials follows the placement of the order.

Various materials are required to produce distinct components of the valves. The materials are located in the inventory. You must acquire the necessary materials from suppliers if they are not in stock.

Once all the primary materials have been collected, the manufacturing team creates a checklist to ensure every item is in stock to commence production.

The quality assurance team will additionally inspect the materials utilized in the production of valves.  Moreover, it contributes to the implementation of quality, consistency, compliance, and efficiency, ultimately resulting in customer satisfaction and a positive image for the company.

The manufacturing process of electric valves encompasses the construction of the stem, seat, and valve bodies. Casting is the process utilized in the fabrication of these valve components. A forged method, which also includes cutting and forging, trimming, sandblasting, machining, and surface treatment, is employed by some manufacturers. The valve bodies may be cast from moulds or centers or fabricated from a single piece. Modern casting processes create components with intricate interior cavities by utilizing a core.

Valve assembly procedures must be strictly adhered to throughout the manufacturing process. Before assembly, the main components of the industrial valve must be cleansed.

Once the manufacturing process is finished, the individual components must be reassembled into a functioning valve. The valve’s body typically functions as a reference component during the valve assembly.

Pressure testing must be performed on the valves following assembly. Hydrostatic pressure testing is the most fundamental method for examining industrial valves.

To conduct the test, the valve is opened partially and subjected to a hydrostatic pressure 50% greater than its designated operational pressure.The sealing surface of the valve must remain impervious to leaks, and the pressure applied must not fall below its rated working pressure.

The final stage in the production of manufacturing valves consists of inspection and quality control. It is necessary to inspect every valve to ensure that none are defective or leaking.

Manufacturing companies of industrial valves must prioritize inspection and quality control. A QA is designated to assess the integrity of the final product.

The supply chain can be optimized with the assistance of logistics, which ensures that raw materials and components are delivered to the manufacturing site promptly and more effectively. The electric valve wholesaler collaborates with its logistics partners to ensure that their products are delivered to customers on time. It is necessary to have distribution channels that are effective and precise in inventory management.

Factors to Consider When Choosing an Electric Valve

manufacturing process of electric valves

System requirements must be considered when choosing motor-operated valves for a given system. Pressure is one of the most crucial factors to consider. Without failure or malfunction, the valve must be capable of withstanding the utmost pressure of the system. Moreover, temperature becomes an imperative consideration, mainly when the fluid flow via the system is of a warm or chilly nature. The valve must resist degradation or failure within the fluid’s temperature range.

Flow rate, which leads to the volume of fluid traversing the system in a given time, is a crucial factor to consider. The valve’s capacity should suit the system’s highest discharge rate. Refrain from paying attention to account for these system prerequisites, which may give rise to a suboptimal functioning valve of an incorrect size, potentially culminating in the system’s failure.

Function of the valve (on/off, modulating)

When selecting an electric valve, it is essential to consider whether it operates as an on/off or modulating device. Designed to be completely opened or closed, on/off valves are most suitable for systems requiring straightforward on/off control, such as heating or cooling systems. Modulating valves, conversely, offer the capability to initiate or terminate flow and are well-suited for applications that need accurate flow regulation, like hydronic heating systems.

It is critical to select the proper valve function to ensure that the valve fulfills the control requirements of the system. Neglecting the function of the valve leads to a regulated system that fails to operate at its maximum potential.

Media type (air, water, steam)

The media variety is another crucial element when choosing a motor-operated valve. The material of the valve must be compatible with the air, water, or vapor that the system transports. A variety of media types need distinct valve materials. For instance, valves utilized in water systems must be corrosion-resistant, whereas valves used in steam systems must withstand high temperatures and pressures.

Incorrect valve material selection may result in leakage, early valve failure, and other complications that cause system failure. As a result, it is critical to determine which valve material is most suitable for the media carried by the system.

Valve material (brass, bronze, stainless steel)

A vital aspect to note when selecting a motor valve is the valve’s material composition. An assortment of valves are constructed from distinct materials, each possessing unique merits and drawbacks. Brass valves, for instance, are resistant to corrosion and able to withstand high pressures; however, they cannot utilized in corrosive or alkaline environments.

In addition to being corrosion-resistant and suitable for marine environments, bronze valves cannot be utilized in high-temperature applications. Ideal for use in steam systems, stainless steel valves are resistant to corrosion and can sustain high temperatures. Choosing the proper valve material is critical to ensure the valve can endure the system’s needs without early failing.

Type of electric valve

A motorized valve actuator price is a form of valve whose opening and closure are controlled by an electric motor. A variety of motorized valves exist, each possessing distinct characteristics and applications. The ball valve is an example of a motorized valve variety. It regulates fluid passage using a rotating spheroid with a perforation at its core. An alternative design is that the gate valve controls fluid flow using a wedge-shaped disk or gate.

The third form is the butterfly valve, which controls the flow with a disc that rotates 90 degrees. These valves are used to regulate the passage of enormous volumes. The globe, diaphragm, and solenoid valves are motorized for precise regulation. Other system requirements, including the controlled fluid, pressure, temperature, and flow rate, determine the type of motorized valve necessary.

Electrical requirements (voltage, current)

Additionally, it is critical to consider the motorized valve’s electrical requirements when selecting. To function, motorized valves necessitate an electrical current; therefore, the voltage and current specifications of the valve must align with the system’s electrical supply. Failure to consider the electrical requirements may lead to a valve that does not operate properly or damage to the system’s electrical components.

To ensure the valve functions at peak efficiency while preventing damage to the system, choosing one that meets the precise voltage and current specifications is critical. To avoid potential complications, adhering to the manufacturer’s instructions during the installation process of motorized valves that may necessitate particular wiring configurations is vital.

Modulating vs On/Off Valves

There are two distinct varieties of electric valves: regulating and on/off valves. The binary operation of on/off valves is entirely closed or open. These units are appropriate for systems in which precise control is not necessary. By altering the position of the valve, regulating valves ensure precise flow control. Therefore, they are ideal for process control and HVAC systems requiring specific flow. Whether regulating valves or on/off valves are utilized will depend on the specifications of the system and the necessary level of control.

How To Choose a Reliable Electric Valve Manufacturer

Selecting the most reputable electric valve supplier when purchasing an electric valve for a given application is critical. We consistently recognize the fundamental needs and preferences. Our objective should be to buy a product of reasonable cost and high quality. The price element is vital to every transaction.

These factors exert an influence on your enterprise. Since most valve manufacturers do not provide after-sale service, you must select the most suitable and optimal manufacturer to meet your needs. To choose the most reputable valve manufacturer.

Knowledge of the intended market

Electric valve manufacturers are prone to feeling more intimidated by prevalent quality concerns linked to their merchandise. They can meticulously manage and resolve the issues. Notably, most electric valve manufacturers specialize in producing a single product category or type.

When an electric valve supplier asserts that they manufacture a wide variety of products, they operate within the realm of trendsetting companies.

Quality of the product and reliability

Exactly what you need is a reputable manufacturer of valves. However, obtaining a high-quality product should be your top priority. Nobody desires to possess products of inferior quality in this world. Suitable quality valves are a requirement for all consumers. Inspect the quality of the valves thoroughly. An approach that directs purchasers to procure samples directly from the manufacturer and conducts thorough inspections of the valves. Conduct proper testing on your model to ensure its reliability and durability.

Valve maintenance assistance

Even correctly maintained valves may require repair in some circumstance. Consider a valve manufacturer that offers direct valve repairs on an extensive range of valves. Are members of the Valve Repair Council as well. While having works repaired, verify that the National Board for Repair Services accredits the manufacturer. Those valves bearing one of these labels will have their specifications restored to their initial state. Assess the manufacturer’s personnel regarding their industry expertise and factory training received directly from the valve producers.

Actuator service and sales

Select a company that possesses knowledge regarding the correlation between actuators and valves. Choose the manufacturer who can assist in product selection for your entire endeavor. Select the manufacturer of sophisticated pneumatic actuators that best meets the specifications of your application. Locate a manufacturer who provides services for actuators and valves and can direct you to the appropriate products. 

Inventory on hand

At what quantity does the manufacturer maintain inventory? This number directly affects the time required to receive your valves and parts, which is critical in an emergency or unforeseen malfunction. Collaborating with a valve supplier that upholds a substantial inventory will enhance the likelihood that the necessary products will be accessible at the designated time.

Occurrences of regulation are rapid, and workplace safety is a critical concern in the vicinity of manufacturing facilities. Identify the valve manufacturer that complies with all safety standards, especially those about high-pressure valves, in response to a report that revealed a systemic deficiency in gas pipeline oversight. To ensure that your projects adhere to all applicable regulations, you must choose a valve manufacturer with a track record of demonstrating a commitment to safety and expertise regarding the relevant standards.

Compare the Price with the Quality

Price and quality are the most influential and crucial factors when selecting the finest valve manufacturer for your industry. When pricing is exorbitant, sales frequently suffer, even when every other aspect is flawless. Therefore, investigate the price of each variety of valve. Assess whether the quality of the product justifies its price. Compare prices from various manufacturers to select the optimal valves supplier. However, be wary of con artists who offer discounted prices.

A practical approach to decision-making involves conducting a price comparison among various valve manufacturers. Begin the process by compiling a list of potential valves from manufacturers. 

Valve warranty, guarantee policy

A warranty is a commitment made by the manufacturer to the consumer. It could ensure that you obtain the desired products and services. Confirm that the valve manufacturer offers a product warranty with customary terms and conditions.

Upon the advice of the valve manufacturer, Plumberstar has a 3-year warranty on all valve parts. Select the suitable valve for your specific application. And they might not. The return policy ought to be exhaustive and transparent.

Shipping Service

Analyze the complete delivery procedure employed by the valve manufacturer. Your orders must be delivered to their intended locations without incident. Determine whether or not they offer door-to-door service. Because of this, Obtaining the valves from an alternative location will undoubtedly present challenges.

Electric Ball Valve Vs Solenoid Valve

Both solenoid valves and electric ball valves are automated media control valves. The distinctions in their operations indicate which valve type is more suitable for specific applications. This comparison studies the distinct characteristics that differentiate solenoid valves from electric ball valves to facilitate the choice between the two types of valves. 

solenoid valves with brass type

What Is A Solenoid Valve?

An electromechanical device, a solenoid valve comprises a coil encircling an actuator linked to a valve or seal mechanism. A magnetic field is produced when current passes through the coil; this field controls the closure or opening of the valve via the actuator. Consult our article on solenoid valves for additional details.

What Is An Electric Ball Valve?

An electric motor drives a ball within the interior of an electric ball valve. A port is located in the center of the spheroid. Upon the valve opening, the alignment of the ball’s port with the inlet and outlets facilitates fluid passage through the valve. The body of the ball blocks flows through the valve when closed, resulting in the port being perpendicular to both the inlet and outlets.

Electric ball valves generally require a minimum of two to three seconds and sometimes an extended duration when moving from a closed to an open position. Due to their virtually instantaneous operation, solenoid valves are the superior choice for applications that need an exceptionally rapid response time from the valve. Examples include applications involving compressed air, heating, and car washes. Flow rates are more significant with electric ball valves than with solenoid valves. Several variables, including the type of valve, the pressure drop, and the Kv factor, determine the flow rate.

Electric ball and solenoid valves are designed to control on/off. However, a design option exists for each form of valve to achieve more precise flow regulation. Read up on proportional solenoid and v-port ball valves to gain further insight. 

Electric ball valves are significantly more effective than solenoid valves at handling media containing microscopic particles. A solenoid valve is susceptible to rapid clogging by particles, whereas the movement of the ball valve across its seat tends to expel particles. Consult the manufacturer’s manual of the valve for additional information regarding the utmost particle size and whether a filter is necessary in front of the valve for a given application.

The power consumption of solenoid valves is greater than that of electric ball valves. More power is typically required to maintain the energized state of a solenoid valve compared to the power needed to open or close the valve. However, electric ball valves solely necessitate power for opening and closing, with no power requirement for valve maintenance. However, there are designs of solenoid valves that can remain in that position without the need for power. For more information, consult our article on latching solenoid valves.

When deactivated, solenoid valves are either open or closed. When a malfunction occurs, such as an electrical outage, these valves will remain immobile in the de-energized state. The user can use this information to determine whether the valve should be closed or opened in case of a malfunction. Usually, electric ball valves lack this capability. 

Solenoid valves cannot withstand higher pressures than ball valves, particularly high-pressure ones. Ball valves designed for high-pressure applications can withstand up to 700 bar (10.000 psi). Conversely, an indirect-acting solenoid valve designed for high pressure is limited to operating at a maximum of 90 bar (1300 psi). Indirect-acting solenoid valves can manage pressures of up to 16 bar (232 psi). 

Electric ball valves are considered superior when the diameter is 50 mm (2 inches). Additionally, when choosing a solenoid valve between 50 mm and 12.7 mm (0.5 inches) in size, opt for a semi-direct or indirect solenoid valve rather than a direct-acting one. Direct-acting solenoid valves function solely on the magnetic force generated by the solenoid. Consequently, solenoid dimensions that exceed 12.7 mm in diameter precipitate astronomical costs. 

Advantages of Electric Valve:

The primary benefit of electric valves is their capacity to regulate the passage of fluids in a system with extreme accuracy and precision. Complex processes in numerous adjustments might be required to attain the intended result, and I find this particularly advantageous. In addition to preventing human error, motorized valves operate automatically, assuring consistent performance.

Furthermore, these valves exhibit superior energy efficiency compared to manual valves due to their requirement for only-when activation.

Additionally, rotary valves provide enhanced adaptability to accommodate various media or operating pressures compared to manual valves. In addition, they are frequently able to be seamlessly incorporated into pre-existing systems, enabling them to start operations promptly and without causing any disruption to production processes.

Manual valves are less precise than electric valves. The ability to remotely control electric valves is advantageous for various applications.

Electric valves are available in various materials, including brass, plastic, and stainless steel. They apply to both low-pressure and high-pressure applications. Chemical, pharmaceutical, and food and beverage industries are among those that utilize them.

Disadvantages of Electric Valve:

An additional drawback associated with motorized valves is their potential difficulty in detection. Because they are generally only available at select hardware or plumbing retailers, individuals requiring them might be compelled to procure them from specialized wholesale suppliers or manufacturers.

When motorized valves are used, electrical problems can happen in some homes or businesses. A power outage prevents the valve from opening or closing, potentially leading to significant complications. Moreover, if the power supply fails during the operation of the valve, it may become immobile in that particular position.

A vital drawback associated with motorized valves is their potential for high costs. They are constructed from premium materials and require extreme precision. Furthermore, installation and maintenance expenses are relatively high.


Advantages and Disadvantages of Electric Valve

Motorized valves may also produce noise when operating, an additional potential drawback. Distracting from other activities or conversations, this commotion may cause difficulty for individuals. Occasionally, the noise level could be sufficiently high to induce auditory impairment.

motorized electric ball valve

Comparison Between an Electric Valve and A Pneumatic Valve

The intended use is an additional consideration when deciding between pneumatic and electric valves. Applications requiring low to moderate pressure are well-suited for pneumatic valves, whereas high-pressure operations are more suitable for electric valves. Typical applications for electric valves include gas, steam, and other media that need precise control and rapid response times.

electric valve and pneumatic valve


Pneumatic valves regulate the flow of fluids or gases through compressed air or gas—however, an electric current powers electric valves. Since an external source powers the electric valve, it is most suitable for sites with a consistent power grid. In contrast, pneumatic valves are more affordable and easy to install; however, they need an air compressor.

Accuracy and speed:

In addition to regulating gas or fluid flow in real-time, electric valves are more precise and quicker than pneumatic valves. In addition, for more accurate and rapid regulation, electronic valves may be integrated with programmable logic controllers (PLCs). In contrast, due to their reliance on air pressure, pneumatic valves operate slower than their electric valve and require better precision.


Electric valves are not preferred when operating in unsafe environments, such as chemical facilities that handle corrosive substances. Pneumatic valves are the preferred choice. This is because pneumatic valves do not generate electrical charges that could cause corrosion or ignition. Electric valves have the potential to generate sparks, which may result in electric shocks that are perilous and could inflict harm.


Electric valves require more complex maintenance procedures than pneumatic valves. They need less technical knowledge and are less complicated. Electric valves may exhibit more excellent durability but require more frequent maintenance.

A more proficient technician is required to handle electric valves due to the presence of complex electronic components, such as solenoids or sensors, which are susceptible to malfunction

Raw Materials Used in Electric Valve Manufacturing

As it determines the valve’s performance in particular environments and circumstances, selecting material is critical in industrial valve production. In consideration of various performance criteria and applications, a variety of materials are frequently employed.

Integral to the industrial valve manufacturing process, quality control makes sure that the final product conforms to all applicable standards and specifications. Manufacturers of industrial valves implement a variety of quality control procedures, including:

  • Raw material inspection
  • Inspection of the manufacturing process during machining and assembly
  • Defect detection and performance evaluation via pressure testing
  • Finishing inspection and quality assurance before shipment

These protocols ensure that the manufactured valves are of optimal quality and will operate effectively in their designated uses.

How Does an Electric Valve Actuator Work?

motorized valve brass body

Electric valve actuators control a valve opening or closing. They are compatible with various valve types, such as ball and butterfly valves, and can generate either linear or rotary motion. Electric valve actuators are vital for assisting closed or dispersed systems over a large area, as they respond to commands via remote control or centralized process control systems.

By controlling electric actuators from a centralized system by programmed and organized instructions, process control systems enable businesses to automate the system and increase its reliability. Electric valve actuators generally advance in response innovation and ease of use.

An electric ball valve has an electric motor that spins a ball inside the valve's body. A port is located in the center of the spheroid. Upon the valve opening, the alignment of the ball's port with the inlet and exhaust ports facilitates fluid passage through the valve. When the valve is closed, the port will be perpendicular to the inlet and outlet ports, permitting the ball block bodies to pass through the valve.

The electric ball valve is managed through the control panel that encompasses the entire system. A connection exists between the control panel and the electric motor that generates the propelling torque or force.

In addition, the electric ball valve is equipped with a gearbox system that regulates the valve's speed. As the gear and propelling force increase, the rotational speed of the electric ball valve.

Determining the electric current to the motor and operating gear is required to regulate the ball valve's motion.

In addition to the control panel, the electric ball valves have limit switches that regulate the electric current flow. The limit switch is activated in response to the valve's state of closure or opening, controlling the electric current flow.

To manually remove the solenoid valve from the seat, specific models a manual operator consisting of a twist head or press mechanism activated with a screwdriver. In the absence of a manual operator, the only alternative is to remove the coil, install a Commissioning Magnet in its place, and then remove it again when the task is complete. The permanent magnet's magnetic field compensates for the electromagnetic field generated during coil energization. 

Three electric ball valves typically exist, with sizes of ½ inch, ¾ inch,1 inch, and 1 1/4, 1½ inches. It depends on the project and what size you need. For example, when installing a hose connector with an outdoor faucet, the corresponding measurement is probably between ½-inch and ¾-inch. Because water constantly flows through both pipelines at any moment, a 1-inch valve is undoubtedly what you will need if your plumbing project involves a bathroom sink with two sinks.

Valve components are critical to any electrical system. They regulate the passage of current, permitting it to be manually activated or deactivated. However, every ball valve is not created equal. Before proceeding with a purchase, it is crucial to have a clear understanding of your needs.

Manual override is a feature found on numerous electric valves. This grants the operator access for maintenance purposes or power. This feature gives you options and ensures the device will still work if there are power problems. 

Electric three-way valves are versatile devices that let gases or fluids move around or mix in a system. Valve bodies, actuators, and internal components, including seats and gaskets, are constituent parts. The flow direction of these valves is regulated in a precise and automated fashion via an electric actuator.

HVAC systems, industrial processes, and plumbing applications frequently employ three-way electric valves. These devices prove highly advantageous when the flow must be entirely halted, regulated, or redirected. By understanding their inner workings, you can make informed decisions concerning these valves' installation, selection, and upkeep.

The valve must be firmly attached to the lines using the right fittings. Tighten both the valve and the pipe with a wrench. Prevent unwarranted systemic tension.

Positioning the actuator facing upwards during valve installation is advisable, with a maximum deviation of 90 degrees (refer to image). It decreases the likelihood that moisture will accumulate in the actuator.

Align the ball to its proper angular position by employing a tool such as a spanner. The 2-way ball valves are in the standard closed position. By 180 degrees of ball rotation, the three-way ball valves can be configured in two different ways.

Ensure the ball is positioned appropriately within the valve for the actuator to fit tightly. Manually tighten the actuator's nut.
