What is a Normally Open Solenoid Valve?

A Normally Open (NO) Solenoid Valve is a type of valve that remains open when not energized (the solenoid is deactivated). When the solenoid is activated, the valve closes, restricting the flow of the medium. This type of valve is often used in applications where you want to allow the flow of liquid or gas to occur by default, and only interrupt the flow when necessary (i.e., when the solenoid is energized). Applications of Normally Open Solenoid Valves: Water Treatment: Used to control water flow in automatic systems. Gas Systems: For controlling gas flow in various industrial processes.
