Solenoid Valve D30

The D30 type solenoid valve has a closed cavity, through holes are opened in different positions, each hole is connected to a different oil pipe, the piston is in the middle of the cavity, and the two sides are two electromagnets. Which side of the magnet coil energizes the valve body and is attracted. On which side, by controlling the movement of the valve body to open or close different oil discharge holes, and the oil inlet hole is normally open, the hydraulic oil will enter different oil discharge pipes, and then the pressure of the oil will be used to push the piston of the oil cylinder. The piston also drives the piston rod and the piston rod drives the mechanical device.
