A normally open solenoid valve (NOSV) is an essential component widely used in various industries for controlling the flow of liquids or gases. It operates by using a solenoid, which is an electromagnetic coil, to control the valve's opening and closing. When the solenoid is energized, it pulls a plunger to close the valve, allowing the flow of the medium to be stopped. Conversely, when the solenoid is de-energized, the valve remains open, permitting the flow to resume. This type of solenoid valve is typically employed in applications where the default state of the valve needs to be open and only needs to close when powered.

Understanding the Mechanism of Normally Open Solenoid Valves
Normally open solenoid valves are known for their straightforward operation and high efficiency. The valve's design consists of a solenoid coil, a plunger, a spring, and the valve body. When the solenoid is not powered, the spring holds the plunger in an open position, allowing the passage for fluid or gas. Upon activation, the solenoid coil creates a magnetic field that draws the plunger downward, closing the valve and stopping the flow.
This type of valve is favored in situations where continuous flow is required until the valve is specifically shut off by external control, such as in irrigation systems, chemical processing, or cooling systems. The simplicity of its design makes it cost-effective while still providing reliable performance.
