Application

High pressure gas filling system: petrochemical, electric power, machinery, medical, scientific research, filling, building, combustionengine, pipeline medium automatic control and other fields.

Features

Small size; Exquisite type; Differential pressure start, quick switchand good sealing; Autocratic coil, not easy to burn; It is suitable forpipeline automation control of high pressure system.

Principle

It is a combination principle of direct operation and  pilotoperation. After power is applied, the electromagnetic forcedirectly opens the pilot small valve, leading the medium in theupper chamber, reducing the pressure, leading the main valve coreupward and passing the fluid medium. After the power is cut off,the pilot valve closes the pilot valve port under the urging of springforce or medium pressure, and the valve core moves downward toclose the valve port and cut off the fluid medium.
