Working Principle of Normally Opened Solenoid Valve

1. After electrification, the valve body in the magnet coil in the normally open solenoid valve is sucked up.

2. The control valve body in the open solenoid valve is moved to block different oil drain holes, and the hydraulic oil will enter different oil drain pipes through the open oil holes.

3. The piston of cylinder moves under the pressure of hydraulic oil and then pushes the piston rod. The piston rod pushes the mechanical device to move.

The basic principle of the normally open solenoid valve is to control the movement of the mechanical device by controlling the current of the electromagnet. The internal structure of the normally open solenoid valve is a sealed chamber, and the middle of the other chamber.
