A brief introduction to pneumatic control valve

Pneumatic control valves use compressed gas as the power source, cylinders as actuators, and valve positioners, converters, solenoid valves, position-holding valves, gas tanks, gas filters and other accessories to drive valves, realize switch quantity or proportional regulation, and receive control signals from industrial automation control systems to adjust pipeline media: flow, pressure, temperature, liquid level and other process parameters. The characteristics of pneumatic control valves are simple control, fast response, and inherent safety, without the need for additional explosion-proof measures.
