Solenoid valve is used to control the automation of basic components of fluid, is actuator; not limited to hydraulic, pneumatic. Solenoid valve used to control the direction of hydraulic flow machines in plant generally controlled by hydraulic cylinder, the solenoid valve will be used.
The working principle of electromagnetic valve, solenoid valve in a closed chamber, in a different position with holes, each hole leads to a different pipeline, valve chamber in the middle, both sides are two electromagnets, which side of the magnet coil power valve will be attracted to which side, by controlling the body's movement to a different file live or leaked oil discharge hole, and into the hole is always open, hydraulic oil flows to different hoses, and then oil pressure to push oil just the piston, piston rod then drive the piston rod drive mechanism moving. This current by controlling the electromagnet to control the mechanical movement.

The system is easy, they take the computer, low prices. coil valve itself is easy, the worth is also low, compared to different forms of valve actuators easy to put in and maintain. a lot of important is that the composition of the automatic system a lot of easier, much lower price.
