Electromagnetic solenoid valve is controlled industrial equipment, used in industrial control systems to adjust the direction of media, flow, speed and other parameters. Solenoid valve is controlled by electromagnetic effects, the main control by relays. In this way, the solenoid valve can match different circuits to achieve the desired control, and control of the accuracy and flexibility are guaranteed. There are a variety of solenoid valves, solenoid valves of different control systems in different locations to play a role, the most commonly used one-way valve, safety valve, directional control valves, speed regulating valve. 
 Solenoid valve in a closed chamber, opened in different locations through-hole, each hole is leading to a different pipeline, the middle of the valve chamber, two is two electromagnets, magnet coils which body surface will be attracted to which side, through the control valve to block the movement of an oil discharge or leakage of different holes, and into the hole is always open, the hydraulic oil will enter a different row of tubing, then push through the oil pressure to the fuel tank pistons, piston and piston rod drive, moving the piston rod drive mechanism. This electrical flow through the control solenoid on-off control of the mechanical movement.
