What is a pneumatic control valve?

Pneumatic control valve, that is, pneumatic control valve, takes compressed gas as the power source and cylinder as the actuator, drives the valve to realize on-off or proportional adjustment with the help of valve positioner, converter, solenoid valve, position maintaining valve, gas storage tank, gas filter and other accessories, receives the control signal of industrial automation control system, and completes the adjustment of various process parameters such as flow, pressure, temperature and liquid level of pipeline medium.

According to the valve action mode, it can be divided into two modes: straight stroke and angular stroke.

Working principle of pneumatic control valve: Pneumatic control valve is composed of executive mechanism and regulating mechanism. The actuator is the thrust component of the regulating valve, which generates corresponding thrust according to the pressure of the control signal to push the regulating mechanism to move. The valve body is the regulating part of the pneumatic regulating valve, which is in direct contact with the regulating medium to regulate the flow of fluid.

Characteristics of pneumatic control valve: simple control, rapid response, intrinsic safety, no need to take additional explosion-proof measures.
