A solenoid valve is an electromechanicaly operated valve.
Solenoid valves differ in the characteristics of the electric current they use, the strength of the magnetic field they generate, the mechanism they use to regulate the fluid, and the type and characteristics of fluid they control. The mechanism varies from linear action, plunger-type actuators to pivoted-armature actuators and rocker actuators. The valve can use a two-port design to regulate a flow or use a three or more port design to switch flows between ports. Multiple solenoid valves can be placed together on a manifold.
Solenoid valves are the most frequently used control elements in fluidics. Their tasks are to shut off, release, dose, distribute or mix fluids. They are found in many application areas. Solenoids offer fast and safe switching, high reliability, long service life, good medium compatibility of the materials used, low control power and compact design.

Solenoid Valve Application
Specialised applications:If the production process involves liquid food products, the plastics and elastomers used should also conform to the local food and hygiene regulations. In addition, some processes require a cleaning cycle to be performed in between production processes and so the data is also required for this procedure as well to ensure there is no undue material degradation caused by steam or cleansing chemicals.
Some applications involve potentially explosive atmospheres and therefore any equipment operating in this environment must have been certified to the appropriate ATEX directives. Similarly, components for other specialised applications such as cryogenic systems, must be designed to not only withstand the extreme temperature but continue to operate reliably.
