Product Details

Pneumatic diaphragm control valve is the terminal industrial process measurement and control system control device, is composed by pneumatic diaphragm actuator, direct through single-seat,double seat and sleeve valve, etc., which can automatically change the valve trim position according to the control signal system , changing the flow area between the valve trim and the valve seat, to change the valve drag coefficient, to realize the regulation for the medium flow, pressure and level and other process parameters adjustment. 
Pneumatic diaphragm valve use dual-oriented structure, equipped with multiple spring actuator, with a compact, light weight, sensitive, valve capacity big, flow characteristics of precision, easy to disassembly. Widely used for precise control of gas, liquid, steam and other media, process parameters such as pressure, flow, temperature, level maintained at a set value. Especially for the smaller amount of pressure and small leakage workplace.
