Gaimi Pneumatic Diaphragm Valve Diaphragm Valve Production

Gaimi pneumatic diaphragm valveIntroduction:

The precision small pneumatic piston diaphragm regulating valve consists of a diaphragm valve and a pneumatic actuator. It is powered by compressed air and regulates the flow rate of fluid medium in the process pipeline. Due to the use of a valve body with a corrosion-resistant lining and a corrosion-resistant diaphragm, a non stuffing box structure, an elastic diaphragm as the throttling element, and a smooth valve body flow channel, pneumatic diaphragm valves have the advantages of low negative force, high flow rate, no leakage, convenience, reliability, fire and explosion prevention. They are widely used for flow regulation of strong acids, strong alkalis, strong corrosives, high viscosity, grain containing, fiber containing, toxic and non polluting media in industrial automation systems.

The closing and opening of the diaphragm valve is achieved by the pressure from the pipeline acting on the reinforced rubber diaphragm. When the pressure medium enters the valve control chamber, the diaphragm is pressed down and the valve channel is closed. When the pressure in the control chamber is discharged to the atmosphere or downstream pipeline, the diaphragm rises and the valve channel is opened. Valves do not have valve stems, gaskets, directional seats, etc. The moving component in the channel is the diaphragm, so there is no rusting or locking phenomenon, and it has higher stability. Multiple structural and control forms, suitable for various fluid control needs.
