A solenoid valve is an electromechanical valve used with liquid, gas or air and is controlled by running or stopping an electrical current through a solenoid, thus changing the state of the valve. The solenoid is an electromagnetic part of a valve, comprised of a coil,core-tube, core and enclosure. Solenoid valves may have two or more ports: in the case of a two-port valve the flow is switched on or off; in the case of a three-port valve, the outflow is switched between the two outlet ports. Multiple solenoid valves can be placed together on a manifold

Solenoid valves consist of two main parts: the solenoid and the valve. The solenoid converts electrical energy into mechanical energy which, in turn, opens or closes the valve mechanically. Solenoid valves may use metal seals or rubber seals, and may also have electrical interfaces to allow for easy control. A solenoid valve can also function as an Air Pilot which the Cv-flow assists the cycling opertaion of the valve. A spring may also be used to hold the valve opened or closed while the valve is not activated.
