How Do Solenoids Work?

A solenoid valve operates using an electromagnet to control the opening and closing of an orifice within the valve body. This mechanism regulates the flow of liquids or gases with precision.

When the electromagnet is energised, it moves a plunger that either opens or closes the valve, depending on its specific configuration. This setup enables accurate fluid flow control in a range of applications, including machine tools, chemical processing, and water treatment systems.

There are several types of solenoid valves available, including:

Normally closed (NC) valves
Normally open (NO) valves
Bi-stable (latching) valves
2-port valves
3-port valves
