normally closed solenoid valve: an essential component for fluid control systems
Release time:2025-02-27 01:59:27
A Normally Closed Solenoid Valve (N.C. Solenoid Valve) plays a crucial role in controlling the flow of liquids and gases in various industrial and commercial applications. This type of valve remains closed when there is no power supply to the solenoid and only opens when an electrical current is applied, allowing the flow of fluid. Its simple yet effective design makes it indispensable in systems requiring precise control over the flow of substances.
Understanding the Normally Closed Solenoid Valve
The basic function of a Normally Closed (N.C.) Solenoid Valve is to either stop or allow the flow of a fluid when an electrical signal is applied. It consists of a solenoid (electromagnetic coil), a valve body, and a plunger or actuator. The solenoid coil is powered by an electrical current, which generates a magnetic field. This magnetic field pulls the plunger away from the valve seat, allowing the fluid to flow through the valve.
In its default state—when the solenoid is not energized—the plunger is pushed onto the valve seat by a spring, preventing the flow of fluid. This "normally closed" position ensures that no fluid can pass unless the valve is activated by electricity.
