Single seat pneumatic diaphragm by the pneumatic spring diaphragm actuator and low flow resistance single seat valve, regulating valve with stable operation, reliable operating characteristics, small seat leakage and accurate flow characteristics, wide adjustable range etc.. The pressure rating from 1.6Mpa to 11.0Mpa, rated flow coefficient Kv is small, and can be used in many occasions need precise control of micro flow, such as fine chemicals, food additives, medicine, electronics and other industries.

Pneumatic control valve is characterized by simple control, fast response, and intrinsically safe, no need to take another explosion-proof measures, applicable to leakage requirements strict, before and after the valve pressure difference and a certain viscosity and a small amount of fiber medium occasions.

Working principle of pneumatic film single hire Euro regulating valve:
Single seat pneumatic diaphragm regulating valve with compressed air as power source, and with the help of electrical valve positioner, converter, solenoid valve, position control valve and other accessories to drive the valve movement, change between the spool and the valve seat of the circulation area, so as to achieve the role of regulating flow, switch or proportional regulator, receiving the control signal automatic control the industrial system, to complete the flow, pressure, temperature and other parameters regulating pipeline.

     Single seat pneumatic diaphragm control valve dynamic working principle diagram

Single seat pneumatic diaphragm control valve open gas off gas, gas valve is increased with the increase of signal pressure gradually opened, when no signal is in the closed state of the valve; the gas valve closed is increased with the increase of signal pressure gradually closed, no signal, the valve is fully open.
