An electromechanical valve is used to disconnect the fluid and gas path. The electric valve converts electrical energy to rotate, open or close, even if it is mechanical. Mode of operation. Solenoid valve: When the current is applied to the valve, a magnetic field coil is created, causing A magnet mode is created in the coil and the operating rod is pulled up, in this case the water valve opens and the water flows. When disconnecting the power, the coil magnet mode disappears and the spring is high on the rod, push it down and the water flow is cut off.
