COVNA ZJH Cage Guide Pneumatic Globe Valve
Pneumatic control valve is to use compressed gas as the power source, the cylinder as the actuator, and with the help of valve positioner, converter, solenoid valve, retaining valve, gas tank, gas filter and other accessories to drive the valve, realize the switch value or proportional adjustment, receive the control signal of industrial automation control system to complete the regulation of pipeline medium: flow, pressure, temperature, liquid level, etc Various process parameters. The characteristics of pneumatic control valve are simple control, rapid response, and intrinsic safety, no need to take additional explosion-proof measures.
