Control valve for regulating the flow of the medium, pressure and level. According to the opening of regulatory signals, automatic control valves, so as to achieve medium flow, pressure and level of regulation.
Pneumatic Control valve that is powered by compressed air source to the actuator cylinder, and the help of electrical valve positioner, electrical switches, solenoid valves and other accessories to drive the valve to achieve proportional switch or adjust the receiver industrial automation control signal control system to complete the regulation of media channels: flow, pressure, temperature and other process parameters. Pneumatic control Control valve is characterized by a simple, rapid response, and intrinsically safe, without additional proof before taking action.
According to the pneumatic Control valve operation mode can be basically divided into: linear and rotary two ways.
