China Pneumatic Diaphragm Control Valve with Cut-off

Pneumatic Diaphragm Control Valve with Cut-off(ZMQ)

Summary:
ZMQ pneumatic diaphragm cutting valve has the function of fast cutting, which is composed of multi-spring pneumatic diaphragm actuator and control valve. Valve body structure has a single seat, sleeve and three-way forms. Through receiving the signal from the control system or adjusting the instrument, the fluid in the process pipeline can be cut off, switched on or switched. It has the characteristics of sensitive reflexes, reliable movement and quick opening and closing. Pneumatic cut-off valve is mainly used in no impurities, no particles of liquid, gas media, the requirements of rapid close, rapid emptying automatic control system.

Advantages:
Pneumatic diaphragm cut-off valve is a new type of high performance cut-off valve with fast speed, large thrust and large flow coefficient. According to the allowable pressure difference, medium characteristics and process pipe requirements, it can choose a single seat, sleeve, three-way cut-off valve. It is widely used in petroleum, chemical, metallurgy, electric power, light industry, textile and other industrial sectors of the production process automatic control and remote control system.
