An NC (Normally Closed) valve is a type of solenoid valve that remains closed when not energized. This means that the flow of fluid is blocked until the valve is activated by an electrical signal. NC valves are commonly used in applications where it is essential to stop the flow of fluid in a system until a specific action occurs.
Characteristics
– Default Position: The valve is closed when no power is applied.
– Activation: The valve opens when an electrical current is supplied to the solenoid.
– Safety: Provides a fail-safe option, as the system remains closed in the event of a power failure.
– Applications: Often used in pneumatic and hydraulic systems, as well as in various automation processes.
Examples
– Water Control Systems: Used to prevent water flow in irrigation systems until activated.
– Gas Supply Systems: Employed in gas lines to ensure that gas is only released when needed.
– Industrial Equipment: Utilized in machinery to control the flow of lubricants or coolants.
