Single-seat pneumatic control valve

Single-seat pneumatic control valve

Pneumatic control valve is powered by compressed gas, with a pneumatic diaphragm head as the actuator, and driven by accessories such as valve positioner, converter, solenoid valve, holding valve, gas storage tank, gas filter, etc., to achieve on/off or proportional adjustment. It receives control signals from industrial automation control system to adjust various process parameters of pipeline media, such as flow rate, pressure, temperature, liquid level, etc. The characteristics of pneumatic control valves are simple control, fast response, and inherent stability, without the need for additional explosion-proof measures

The pneumatic single seat regulating valve cage adopts a compressed valve seat design, which solves the problems of difficult disassembly and large leakage of traditional threaded valve seats, and extends the service life. Adopting a flow open design, the medium tends towards the direction of valve opening, with good controllability of small opening and minimal distortion of flow characteristics. According to the requirements of the working conditions, special valve cages that reduce noise and resist cavitation can be selected.

Pneumatic single seat regulating valve has stable operation, reliable action characteristics, small valve seat leakage, precise flow characteristics, and a wide adjustable range. It will undoubtedly achieve high Zhi control effects in a wide range of applications with unique advantages.
