China has emerged as one of the leading countries in the production and export of solenoid valves, with a wide range of manufacturers offering solutions to various industries. Among the many types of solenoid valves, the Normally Open (NO) solenoid valve stands out for its versatility and broad applications in fluid control systems. This article provides a comprehensive overview of China’s Normally Open Solenoid Valve Manufacturers, their capabilities, and the industries they serve.

What is a Normally Open Solenoid Valve? A Normally Open (NO) solenoid valve is a type of electric valve that remains open when no current is applied to it. This means that when the solenoid coil is not energized, the valve allows fluid (such as air, water, or oil) to flow through. When an electric current is passed through the solenoid, it creates a magnetic field that forces the valve to close, stopping the flow. This design is essential in applications where the default state should be “flowing,” and the flow needs to be stopped only when an external signal is given, such as in automated systems or emergency shutoff processes.
