Solenoid Pneumatic Butterfly Valve

The solenoid valve has a closed cavity, and there are through holes at different positions, each hole is connected with a different oil pipe, the piston is in the middle of the cavity, and two electromagnets are on both sides. Which side of the magnet coil energizes the valve body to which side, by controlling the movement of the valve body to open or close different oil drain holes, and the oil inlet hole is normally open, the hydraulic oil will enter different drain pipes Then, the piston of the cylinder is pushed by the pressure of the oil, and the piston drives the piston rod, and the piston rod drives the mechanical device. This controls the mechanical motion by controlling the current through and off of the electromagnet.
