Description

The Normally Closed (NC) 3/2 Solenoid Valve is one of the most widely used valves in industrial automation and control systems. It provides precise and reliable control of air, gases, and various fluids. The valve features three ports and two operating positions (3/2 Way). It remains closed when the electrical power is disconnected and automatically opens the flow path when the solenoid coil is energized.

With its fast response time, high reliability, and low power consumption, this type of solenoid valve is an ideal solution for pneumatic systems, packaging machinery, production lines, and industrial automation applications.

Operating Principle

The valve operates using an electromagnetic mechanism:

* Normal State (De-energized): The valve remains closed, preventing media flow.
* Energized State: The solenoid coil actuates the magnetic core, opening the flow path and directing the air or fluid according to the valve design.
* Power Off: The internal spring automatically returns the valve to its original closed position.
