How does a direct-acting solenoid valve work?

The direct-acting solenoid valve is generally used with small flow-rate applications.

How does a solenoid valve work?

Stay tuned to find out more. A solenoid valve consists of two basic units: an assembly of the solenoid (the electromagnet) and plunger (the core), and a valve containing an orifice (opening) in which a disc or plug is positioned to control the flow of fluid. The valve is opened or closed by the movement of the magnetic plunger.

What happens when a solenoid is energized?

When the solenoid is energized in a direct acting valve, the core directly opens the orifice of a Normally Closed valve or closes the orifice of a Normally Open valve.
