Electromagnetic valve is used to control the direction of flow of automation basic element, belongs to the actuator; Usually used for mechanical control and industrial valve above, to medium direction control, so as to achieve the valve switch control.

Principle:

Electromagnetic valve has closed cavity, in different locations are open through-hole, each hole all leads to different tubing, cavity intermediate is valve, both sides are two pieces of electromagnet, which face the magnet coil electricity will be attracted to the body which side, by controlling the movement of the body to block or leak out different discharge hole, and the oil hole is always open, hydraulic fluid will enter the different oil drain, and then through the oil pressure to push oil cylinder piston, piston and piston rod driven, piston driven mechanical devices moving. So through the control electromagnet electric circulation fault controls the mechanical movement.
