Pneumatic diaphragm regulating valve, pneumatic diaphragm single seat regulating valve ZJHP
ZJHP pneumatic diaphragm single seat regulating valve overview:
ZJHP pneumatic diaphragm single seat regulating valve is a top-guided single-seat regulating valve , which has the characteristics of simple structure, good sealing performance, large flow and reliable use. An effective and sufficient top guidance system overcomes vibrations at small openings and has a longer effective life. Can choose multi-spring pneumatic film mechanism or electric actuator .
ZJHP pneumatic diaphragm single seat regulating valve is composed of pneumatic multi-spring diaphragm actuator and low flow resistance single seat valve. The new actuator has a low bottom, light weight, and simple installation. The new valve body has a compact structure, a smooth flow channel and a large Flow Coefficient.
Pneumatic film control valve has stable operation, reliable operation characteristics, accurate flow characteristics, and large adjustable range. Get high-quality control effect in a wide range of applications.

Pneumatic regulating valve is used to regulate the flow, pressure and liquid level of the medium. According to the signal of the adjusting part, the opening degree of the valve is automatically controlled, so as to achieve the adjustment of the medium flow, pressure and liquid level.
Pneumatic control valve uses compressed air as the power source and cylinder as the actuator, and drives the valve with the aid of electrical valve positioner, converter, solenoid valve, retention valve and other accessories to realize on-off or proportional adjustment. The control signals of the automatic control system are used to complete the adjustment of the pipeline medium: flow rate, pressure, temperature and other process parameters. The characteristics of the pneumatic regulating valve are simple control, fast response, and intrinsically safe, and no additional explosion-proof measures need to be taken.
According to the operation mode of the pneumatic regulating valve, it can be basically divided into two types: straight stroke and angular stroke.
The actuator of the pneumatic regulating valve is also optional: diaphragm type cylinder (pneumatic diaphragm regulating valve) and piston type cylinder (pneumatic piston regulating valve)
