Product Description

Wai Hang Sanitary Pneumatic Welded Diaphragm Valve

  The working principle of the pneumatic welding diaphragm valve is to use the pressure generated by the pneumatic actuator to drive the diaphragm up and down. When the pneumatic actuator receives a control signal, the piston inside it will move up and down, thereby pushing the diaphragm to open and close. When the diaphragm rises, the valve opens and the medium can flow; when the diaphragm falls, the valve closes and the medium is cut off.

  The working principle of the pneumatic diaphragm valve is based on the pneumatic drive and the lifting and lowering movement of the diaphragm. When the air source is connected, compressed air or other driving gas enters the pneumatic actuator (usually composed of cylinders, pistons, diaphragms, springs and other components), pushing the piston or diaphragm to move, thereby driving the diaphragm up and down. The movement state of the diaphragm directly determines the opening and closing of the valve.

  There are various standard valve series can be supplied, they are the DIN,3A, SMS, ISO/IDF, BS/RJT, ASME/BPE standard etc. You can choose us with confidence, our products meet the standards of multiple regions, such as American Standards, Japanese Industrial Standard, Korean Standard, German Standard and Italian Standard.

  Pneumatic diaphragm valve is a special type of valve that plays an important role in industrial applications. This paper will introduce the characteristics, working principle, application field, use precautions and maintenance methods of pneumatic diaphragm valve.

  A pneumatic diaphragm valve is a special type of valve that is designed to have a diaphragm that can move within the valve chamber. The diaphragm divides the valve channel into two parts, one part is used to pass the liquid and the other part is used to stop the liquid flow. This design makes the pneumatic diaphragm valve have some unique advantages, such as easy operation, good sealing, and wide flow regulation range.
trait.

1. Simple structure: The structure of pneumatic diaphragm valve is relatively simple, mainly composed of valve body, valve cover, valve, diaphragm and valve stem and other components. This structure makes pneumatic diaphragm valves easy to manufacture and service.

2. A wide range of meteor adjustment: due to the existence of the diaphragm, the pneumatic diaphragm valve can control the change of flow by adjusting the position of the valve. This wide range of adjustments makes it ideal for many application scenarios.

3. Easy to operate: The operation mode of the pneumatic diaphragm valve is very simple, only need to control the movement of the valve stem through the pneumatic driver, you can realize the switch of the valve. This mode of operation makes pneumatic diaphragm valves ideal for use in automated systems.

Working Principle

  The working principle of the pneumatic diaphragm valve is to flow through the pneumatic drive to control the movement of the valve stem, and then promote the position of the diaphragm and the valve pin, when the valve is closed, the diaphragm and the valve will be clear to block the fluid into the pipeline, when the valve is opened, the fluid can flow through the channel, this working principle makes the pneumatic diaphragm valve has a good sealing performance and flow regulation performance.

Application Field

Pneumatic diaphragm valves have a wide range of applications, including but not limited to the following industries:
1. Chemical industry: Pneumatic diaphragm valves play an important role in chemical production, such as fluid control between chemical reactors, storage tanks and pipelines.
2. Water treatment industry: Pneumatic diaphragm valves are also widely used in the field of water treatment, such as controlling the flow and pressure of fluids in sewage treatment, water purification systems and water supply systems.
3. Oil and gas industry: Pneumatic diaphragm valves also play an important role in oil and gas extraction, transportation and processing. It can be used to control the flow of fluid between the tank and the pipeline, while also preventing gas leaks
4. Food and beverage industry: In the food and beverage production process, pneumatic diaphragm valves can be used to control fluid flow and pressure to ensure product quality and production efficiency.
