The electronic double-seat electric regulating valve realizes pressure compensation and valve shut-off by using two sealing lines on the valve core barrel to seal at the same time. The valve seat has upper and lower valve core balls. The thrust of the fluid acting on the upper and lower valve cores is opposite in direction but close in magnitude. The single-seat control valve is larger, but the leakage of this valve is also larger than that of the single-seat valve. It is suitable for clean media occasions where the requirements for leakage are not strict and the pressure difference between the front and rear of the valve is large.

Principle of electronic double seat electric regulating valve
Electronic electric double-seat regulating valve is composed of 3810L series (or PSL series) straight-stroke electronic electric actuator and straight-through double-seat regulating valve body. The standard signal converts the current signal into the corresponding linear displacement, and automatically controls the opening of the regulating valve to achieve continuous adjustment of the pressure, flow, temperature, liquid level and other process parameters of the fluid in the pipeline.

Electronic double seat electric regulating valve features
The electronic electric double-seat regulating valve has the characteristics of compact structure, light weight, sensitive action, large valve capacity, accurate flow characteristics, and convenient disassembly and assembly. Large and clean medium occasions without strict requirements on leakage.
