understanding normally closed solenoid valve: function, applications, and benefits

A Normally Closed Solenoid Valve (NC solenoid valve) is a widely used component in various industrial and commercial systems that require fluid or gas control. It is designed to remain in a closed position when no power is supplied and opens when the solenoid is energized. This simple yet efficient mechanism has become a critical part of many applications due to its reliability and safety features. In this article, we will explore the function, applications, and benefits of the Normally Closed Solenoid Valve, helping you understand why it is an essential component in modern automation and control systems.

Functionality of Normally Closed Solenoid Valves At its core, a Normally Closed Solenoid Valve works on the principle of electromagnetic force. The valve remains closed under normal conditions, which means there is no flow through the valve unless an electrical current is applied to the solenoid coil. When power is supplied to the coil, it generates a magnetic field, pulling or pushing a plunger inside the valve. This movement opens the valve, allowing the flow of fluids or gases through the system. Once the power is cut off, the valve returns to its closed position, usually with the help of a spring or a similar mechanism, thereby halting the flow.
