Pneumatic regulating valve is used to regulate the flow, pressure and liquid level of the medium. According to the signal of the adjusting part, the opening degree of the valve is automatically controlled, so as to achieve the adjustment of the medium flow, pressure and liquid level.

Pneumatic control valve uses compressed air as the power source and cylinder as the actuator, and drives the valve with the aid of electrical valve positioner, converter, solenoid valve, retention valve and other accessories to realize on-off or proportional adjustment. The control signals of the automatic control system are used to complete the adjustment of the pipeline medium: flow rate, pressure, temperature and other process parameters. The characteristics of the pneumatic regulating valve are simple control, fast response, and intrinsically safe, and no additional explosion-proof measures need to be taken.

According to the operation mode of the pneumatic regulating valve, it can be basically divided into two types: straight stroke and angular stroke.

The actuator of the pneumatic regulating valve is also optional: diaphragm type cylinder (pneumatic diaphragm regulating valve) and piston type cylinder (pneumatic piston regulating valve)
