Solenoid valves are vital components in various industrial applications, acting as electromagnetic switches to control the flow of fluids, gases, or steam. Among the different types of solenoid valves, the normally closed (NC) solenoid valve is especially significant due to its fail-safe design, making it widely used in critical systems across industries. In China, manufacturers of normally closed solenoid valves are making significant strides, not only producing high-quality products but also meeting international standards to cater to the growing global demand for advanced fluid control systems.
The Importance of Normally Closed Solenoid Valves A normally closed solenoid valve is designed to be closed when there is no electrical current flowing through its solenoid coil. Upon energizing the solenoid, the magnetic field generated opens the valve, allowing fluid or gas to flow through. When the power is turned off, the valve closes automatically, stopping the flow. This design is essential in applications where safety is paramount, and it ensures that systems remain securely shut when there is no power. Industries like oil and gas, water treatment, pharmaceuticals, and manufacturing often rely on these valves to maintain controlled environments.
