Pneumatic diaphragm valve is a new type of electric valve that uses compressed air as the power source and converts the pneumatic signal into an electrical signal through an actuator to drive the valve action. It has the advantages of simple structure, small volume, light weight, vân vân. It use in the automatic control system of petroleum, hóa chất, metallurgical and other industries as a regulating and intercepting device.

Farpro Company is a leading manufacturer of high-quality pneumatic diaphragm valves, widely used in various industries worldwide. The company’s commitment to quality and innovation has made its products a popular choice for businesses looking for reliable and efficient fluid control solutions.

Pneumatic diaphragm valve working principle

Farpro pneumatic diaphragm valves are specially designed to handle a wide range of corrosive and abrasive fluids. They engineered with high-quality materials that are resistant to corrosion, rust, and wear. The valves are available in different sizes, materials, and designs to suit various applications.

The valve’s actuator is pneumatically driven, allowing it to operate automatically without the need for human intervention. The valve’s simple and reliable design ensures long service life, minimal maintenance requirements, and easy installation.

When the pressure medium enters the valve control chamber, the diaphragm will sink and close the valve passage. When the pressure in the control chamber vents to atmosphere or downstream piping, the diaphragm floats up and opens the valve passage.

The valve does not have a stem, gasket, directional seat, etc., the only component moving in the channel is the diaphragm, so there is no rust and die-hugging phenomenon, with a higher degree of stability.

Pneumatic diaphragm valve advantages

  • Corrosion-resistant: Farpro pneumatic diaphragm valves are made of materials that are highly resistant to corrosion and rust. This makes them suitable for use in harsh environments where corrosive fluids are present.
  • Easy to operate: Normally pneumatic operation of these valves allows automatic control without manual intervention. They are structurally simple to operate and have minimal maintenance.
  • Độ bền: Farpro pneumatic diaphragm valves engineered to last, thanks to their robust design and high-quality materials. They can operate to withstand high pressures, nhiệt độ, and corrosive fluids, making them suitable for heavy-duty applications.
  • Tight shutoff: The valves designed to provide a tight shutoff, preventing leaks and ensuring reliable performance. This is achieved through the use of a flexible diaphragm that seals the valve against the flow of fluid.

One is that the valve does not require a separate stem packing sealing structure, the diaphragm in cutting off the medium at the same time play a stem sealing role.

The second is that the flexible diaphragm closes reliably, even to the dirty liquid can do a good cut off.

Therefore, the manipulation mechanism and the media channel is completely separated. So that the food industry and the pharmaceutical and sanitation industries can purchase pneumatic diaphragm valves. But also for some difficult to convey the media and dangerous media.
