Working principle of the pneumatic pressure control valve mainly involves receiving control signals to adjust the opening of the valve, thereby controlling process parameters such as flow, pressure and temperature of the medium in the pipeline.

The main components of the pneumatic pressure control valve include the pneumatic actuator and valve body. When the air source signal acts on the pneumatic diaphragm, a displacement will be generated, and this displacement will be transmitted to the actuator, causing the valve stem to move. The movement of the valve stem changes the opening of the regulating valve, thereby controlling the flow and pressure of the medium.
