Water solenoid valve

There is a closed cavity in the solenoid valve of the water. There is a hole in different locations. Each hole is directed at different oil pipes. The middle of the cavity is a valve. There are two electromagnets on both sides. Where to be attracted, to live or leak different oil discharge holes through the movement of the valve body, and the pores of the inlet pores are often opened, and the hydraulic oil will enter different oil exhaust pipes, and then promote it through the pressure of oil to promote it. The piston of the oil cylinder, the piston drives the piston, the piston rod drives the mechanical device movement. In this way, the mechanical movement is controlled by controlling the current of the electromagnet.
