Electromagnetic Valve Cavity Head

Working principle of solenoid valve: There is a closed cavity in the solenoid valve, with through holes in different positions, and each hole leads to different oil pipes. There is a valve 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 on which side is energized, and different oil discharge holes will be blocked or leaked by controlling the movement of the valve body, while the oil inlet hole is always open, and the hydraulic oil will enter different oil discharge pipes, and then the piston of the oil cylinder will be driven by the oil pressure, and the piston will drive the piston rod. In this way, the mechanical movement is controlled by controlling the current of the electromagnet.
