There is a closed cavity in the solenoid valve. There are through holes in different positions. Each hole is connected with different oil pipes. There is a piston in the middle of the cavity and two electromagnets on both sides. The valve body will be attracted to which side when the magnet coil is electrified. Different oil drain holes will be opened or closed by controlling the movement of the valve body. The oil inlet hole is normally open, and the hydraulic oil will enter different oil drain pipes, and then pass through The oil pressure pushes the piston of the oil cylinder, the piston drives the piston rod, and the piston rod drives the mechanical device. In this way, the mechanical movement is controlled by controlling the current on and off of the electromagnet.
