What is a solenoid valve?
A solenoid valve is an electromechanically controlled valve, used to control the flow of liquids and gases. The valve features a solenoid, which is an electric coil with a portable ferromagnetic core in its centre. This core is called the plunger. An electric current through the coil generates a magnetic field and the magnetic field exerts a force on the plunger. Hence, the plunger is headed towards the centre of the coil so that the orifice opens. This would be the basic principle that is used to open and close solenoid valves. There are a variety of designs available that enables a valve to be selected to specifically suit the application in question. Read more on solenoid valves here.
How a solenoid is operated valve being made?
A solenoid valve is a control unit that, when electrically energized or de-energized, either shut off or allow fluid flow. When it’s energized, a magnetic field builds up which pulls a plunger against the action of a spring. When de-energized, the plunger or pivoted armature is given back to its original position by the spring action. The actuator takes the form of an electromagnet.
What are the main parameters to consider when selecting a valve?
Cv, Media Compatibility, Pressure, Temperature & Process Fitting
Where are solenoid valves used? You can find the usage of these valves in compressed air technology, industrial automation, heating systems, sprinkler systems, swimming pools, dental equipment, washing machines, car wash systems and irrigation systems.
There are many variations of solenoid valves such as single acting, double acting, one- or two-solenoid valves, direct current or alternating current powered and a different number of ways and positions.
Solenoid Valves are divided into 3 main categories:-
