What is a Solenoid Valve?

A solenoid valve is a type of valve that is controlled by an electric current. A coil of wire, also called an electromagnet, is energized to create a magnetic field that moves a plunger. This movement opens or closes the valve, allowing or shutting off the flow of liquids or gases through it.

Whether your application requires directional control, proportional or miniature valve technology, Emerson provides the industry standard for reliability, adaptability, and energy efficiency.
