understanding the normally open solenoid valve: function, applications, and benefits
Release time:2025-04-10 19:12:55
A solenoid valve is an electromechanical device used to control the flow of fluids or gases in various systems. One of the most commonly used types of solenoid valves is the Normally Open (NO) Solenoid Valve. In this article, we will explore what a Normally Open solenoid valve is, how it operates, and the key advantages it offers in a wide range of industrial applications.
What is a Normally Open Solenoid Valve?
A Normally Open solenoid valve is a type of valve that remains open when the solenoid (electromagnetic coil) is de-energized, meaning no current is flowing through it. In this state, the valve allows fluid or gas to pass freely through. When the solenoid is energized (current flows through the coil), the magnetic field pulls a plunger or actuator, closing the valve and stopping the flow.
In simple terms, the valve's default state is open, and it only closes when the solenoid is activated. This design makes it suitable for systems where the flow of fluid or gas needs to be stopped or regulated on demand.
