Structural principle of double seat regulating valve

Structural Principle

The double seat regulating valve is mainly composed of a valve body, a valve core, a valve seat, and an actuator. Valve bodies are usually made of high-quality carbon steel or stainless steel materials, which have the characteristics of corrosion resistance and wear resistance; The valve core and valve seat are precision machined, with high precision and high sealing performance.

 

Working Principle

The working principle of a double seat regulating valve is to receive control signals from the control system through the actuator, drive the valve core to move inside the valve body, and thereby change the flow rate of the medium in the pipeline. Specifically, when the pneumatic actuator receives a control signal, it will convert it into mechanical motion, driving the valve core to displace inside the valve body, thereby changing the flow cross-sectional area of the medium in the pipeline and achieving the purpose of regulating the medium flow rate.
