China is one of the world’s leading manufacturers of solenoid valves, particularly the normally closed (NC) type. These valves are crucial components in fluid control systems, widely used in various industries, including automation, HVAC, and industrial machinery. As the demand for more sophisticated and reliable fluid control systems rises, China has emerged as a key player in the production and supply of NC solenoid valves, combining advanced manufacturing techniques with cost-effective pricing strategies.

The Role of Normally Closed Solenoid Valves Normally closed solenoid valves are designed to remain in a closed position until an electric current is applied to the coil. This design is ideal for applications where it is important to keep the valve shut until activation is required, such as in irrigation systems, gas control systems, and automation processes. The electric solenoid coil is activated by an electrical current, which generates a magnetic field that opens the valve, allowing fluid or gas to pass through. Once the power is turned off, the valve closes again, ensuring that no unwanted flow occurs.
