Solenoid valves are the most commonly used control elements in fluidics. Their tasks are to shut off, release, dose, distribute or mix fluids. Solenoids offer fast and safe switching, high reliability, long life, good medium compatibility of the materials used, low control power and compact design.
A solenoid valve is an electromechanical valve. The valve is controlled by an electric current through a solenoid, 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 switched between the two outlet ports. Several solenoid valves may be placed together in a manifold.
