China is home to a vast number of manufacturers producing solenoid valves, which are essential components in a variety of industrial applications. Among these, normally closed solenoid valves are widely used in fluid control systems due to their ability to maintain a closed position in the absence of electrical current. These valves are critical for managing the flow of liquids and gases in industries such as water treatment, HVAC, automotive, and industrial automation. In this article, we will explore the significance of China’s normally closed solenoid valve manufacturers and what makes them a leading force in this field.
What are Normally Closed Solenoid Valves? A normally closed (NC) solenoid valve operates in a default closed position when the solenoid coil is not energized. Upon energizing the coil, the valve opens, allowing fluid to pass through. When the electrical signal is removed, the valve returns to its closed state. This makes it ideal for systems that need to stop fluid flow by default and only open when required. These valves are particularly useful in applications where fluid should only flow under controlled conditions or when there is a need for automatic shutoff.
