Solenoid valves applications

A solenoid valve is an electromechanical valve for use with liquid or gas. The valve is controlled by an electric current through a solenoid coil. 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 come in various configurations and sizes, such as 100 , 700 Series Solenoid Valve and 4V400 Series Solenoid Valve and so on. They are used in fluid power pneumatic and hydraulic systems, to control cylinders, fluid power motors or larger industrial valves. Besides controlling the flow of air and fluids solenoids are used in pharmacology experiments, especially for patch-clamp, which can control the application of agonist or antagonist.
