Pneumatic Diaphragm Valve

Pneumatic diaphragm valves mainly consist of angular stroke pneumatic valve actuators, pneumatic triplets, solenoid valves, and diaphragm valves. Pneumatic actuators are generally divided into diaphragm and piston types. The control system controls the air source pressure in the upper and lower chambers of the cylinder through solenoid valves to push the valve stem up and down and control the gap between the diaphragm valve diaphragm and the middle passage, achieving valve opening and closing. The pneumatic diaphragm valve produced by Shanghai Meiyanyi Pump Valve is a special form of shut-off valve, whose opening and closing parts are diaphragms made of soft materials, used to close the flow channel, cut off the fluid, and separate the inner cavity of the valve body and the inner cavity of the valve cover. The advantages of pneumatic diaphragm valves include simple structure, good sealing and anti-corrosion performance, suitable for low pressure, low temperature, highly corrosive and suspended substance containing media.
