Pneumatic three-way regulating valve is mainly composed of  body, spool,seat, stem, piston pneumatic actuator, etc. The working principle of the pneumatic three-way control valve is mainly to adjust the fluid parameters in the pipeline by controlling the pressure and flow of gas. Specifically, when the pressure or flow in the pipeline changes, the sensor converts these signals into electrical signals and transmits them to the control instrument. The control instrument controls the action of the actuator based on the deviation between the set value and the actual value, thereby changing the opening of the valve port to adjust parameters such as medium flow and pressure.
