In the world of automation and fluid control systems, solenoid valves play a crucial role. They are widely used to regulate the flow of liquids and gases in various industries, including water treatment, HVAC, and manufacturing. Among the many types of solenoid valves, the “Normally Closed” (NC) solenoid valve is one of the most common. This type of valve remains closed when there is no power applied, and it opens when an electrical current is passed through the solenoid coil. China, with its strong manufacturing base and competitive prices, has become a global leader in the production of normally closed solenoid valves. In this article, we will explore the market of China Normally Closed Solenoid Valve Manufacturers, their products, and their contributions to the industry.
The Role of Normally Closed Solenoid Valves Before delving into the manufacturers, it is essential to understand the function and significance of normally closed solenoid valves. These valves are designed to maintain a closed position under default conditions. When an electrical signal activates the coil, it generates a magnetic field that pulls the valve open, allowing the flow of fluid or gas. Once the electrical current is switched off, the valve returns to its default closed state. Normally closed solenoid valves are widely used in applications where it is essential to control the flow of liquids or gases automatically. Some of the key uses include：
