Explosion proof electric control valve

Product Details

Explosion proof electric control valve

■product overview

The electronic electric single seat regulating valve is composed ofComposed of 3810L/PSL series electronic electric actuators (intelligent integrated actuators) and single seat regulating valves. The electronic electric actuator is equipped with a built-in servo system and does not require a separate servo amplifier. It can be controlled with input signals and power supply to operate. The electronic actuator has simple connection, and the single seat regulating valve core adopts a top guided sealing performance, which is suitable for situations with strict leakage requirements, small pressure difference before and after the valve, and certain viscosity or fiber like media.

■Main component materials
