A solenoid valve is an electromechanical valve controlled by an electric current through a solenoid coil. It may switch on or off of the fluid flow along the tube/pipe the valve located. It may also used to direct flow between two or more outlet ports. A solenoid valve offers fast and safe switching, high reliability, long service life, good medium compatibility of the materials used, low control power and compact design.
A solenoid valve is one of the most frequently used control elements in pneumatic and hydraulic systems. It is widely used to control cylinders, fluid power motors or larger industrial valves. It is employed in automatic irrigation sprinkler systems, domestic washing machines and dishwashers to control water entry to the machine. Many variations are possible on the basic solenoid valve include one or two solenoid valves, direct current or alternating current powered, different number of ways and positions.
