Solenoid valve (Electromagnetic valve) is made of electromagnetic control of industrial equipment, is used to control the automation component of the fluid, which belongs to the actuator is not restricted to hydraulic, pneumatic. Media used in industrial control systems, flow, speed and other parameters. Solenoid valve can be combined with different circuits to achieve the desired control, and control accuracy and flexibility can be guaranteed. There are many kinds of solenoid valve, solenoid valves of different play a role in different parts of the control system, the most commonly used is the check valve, relief valves, directional control valves, speed control valve and so on.
Electromagnetic valve in has closed of cavity, in different location open has pass hole, each hole connection different of tubing, cavity middle is piston, on both sides is two block electric magnet, which surface of magnet coil power valve body on will was attract to where, through control valve body of mobile to opened or close different of row oil hole, and into oil hole is often open of, hydraulic oil on will into different of row tubing, then through oil of pressure to promoted oil cylinder of piston, piston and led piston rod, piston rod led mechanical device. By controlling the electromagnet current switching control the mechanical motions.
