Pneumatic control valve single seat control valve body, suitable for strict leakage requirements, low pressure difference before and after the valve, with a certain viscosity and a small amount of fiber medium occasions. Pneumatic flow control valves can be divided into two types according to the different switching modes: normal opening and normal closing. The air-closed valve is composed of a positive actuator and a regulating valve body. When the input signal pressure changes from the lower limit to the upper limit, the valve is fully open to fully close. The air-opened valve is composed of reaction actuator and control valve body. When the input signal pressure changes from lower limit to upper limit, the valve closes completely to open completely. Fine and small pneumatic control valves use compressed air as power source, pneumatic thin film or pneumatic piston as actuator, select and distribute pneumatic valve positioner, electrical converter, solenoid valve, holding valve and other accessories to realize switching or proportional regulation, and receive control signals of industrial automation control system to complete pipeline introduction. Quality: Flow, pressure, temperature and other process parameters control.
