The solenoid valve is an automatic basic component used to control the fluid. It belongs to the actuator and is not limited to hydraulic and pneumatic. It is used in industrial control system to adjust the direction, flow rate, speed and other parameters of medium.
Principle: When electrified, the solenoid coil produces electromagnetic force to lift the closing part from the valve seat, and the valve opens; when power is cut off, the electromagnetic force disappears, and the spring presses the closing part on the valve seat, and the valve closes.
