Description
Note: This solenoid valve cannot be used for drinking water.
The coil shell of the explosion-proof solenoid valve has a blocking effect on the gas explosion energy transfer. Especially suitable for the transmission of flammable and explosive media.

Tips: Working Principle of Explosion Proof Solenoid Valve
There is a closed chamber in the explosion-proof solenoid valve, and there are through holes in different positions, each hole leads to different tubing. In the middle of the chamber is a valve, and two electromagnets are on both sides. The valve body will be attracted to which side when the magnet coil is energized. By controlling the movement of the valve body to stop or leak out of different drainage holes, and the oil inlet hole is normally open, the hydraulic oil will enter the different drainage pipe, and then through the pressure of the oil to promote the piston cylinder, piston rod, piston rod to drive the mechanical device.
