Description
A solenoid valve is an electrically controlled valve. The valve features a solenoid, which is an electric coil with a movable ferromagnetic core (plunger) in its center. In the rest position, the plunger closes off a small orifice. An electric current through the coil creates a magnetic field. The magnetic field exerts an upwards force on the plunger opening the orifice. This is the basic principle that is used to open and close solenoid valves.
Features:
Only used for clean liquids and gases.
Indirect operated valves require a pressure differential to function.
Are used to close, open, dose, distribute, or mix the media with 2 or more inlets/outlets.
Fast acting.
Options for manual overrides, ATEX, gas approval, media separation and more.
Can get hot as it requires energy to switch and stay in that position (depending on type).
Common in heating systems, compressed air, vacuum, irrigation, car washes, etc.
