In the modern industrial landscape, solenoid valves play an essential role in automating fluid control systems. Among the various types of solenoid valves, normally closed (NC) solenoid valves are particularly significant, as they remain in a closed position when de-energized, allowing for precise control of fluid flow. This article provides an overview of the manufacturers of normally closed solenoid valves in China, examining their capabilities, market presence, and the factors to consider when choosing a supplier.
Overview of Normally Closed Solenoid Valves Normally closed solenoid valves are electro-mechanical devices that utilize electromagnetic coils to control a movable plunger within the valve. When electrically energized, the coil generates a magnetic field that pulls the plunger upward, opening the valve and allowing fluid to flow through. Upon deactivation, the plunger returns to its original position due to spring force, thus closing the valve. This mechanism makes NC solenoid valves ideal for applications where safety and reliability are paramount, such as in water treatment systems, HVAC equipment, industrial automation, and chemical processing.
