Solenoid valves are essential components in various fluid and gas control systems, playing a key role in industries such as HVAC, automotive, and industrial automation. Among the various types of solenoid valves, the “normally open” (NO) solenoid valve stands out for its unique functionality. This valve remains open when the solenoid is de-energized and only closes when activated, making it ideal for applications where the default state should allow flow. China, known for its robust manufacturing capabilities, is home to a vast array of companies specializing in the production of normally open solenoid valves. This article explores the significance of these manufacturers, their contributions to the global market, and what makes them stand out.

The Growing Demand for Normally Open Solenoid Valves The demand for normally open solenoid valves has surged due to their wide range of applications in fluid, gas, and air control systems. These valves are typically used in automatic control systems, water treatment plants, HVAC systems, and various industrial processes where the valve needs to stay open in the default state, ensuring continuous flow. In industries like oil and gas, automotive, and manufacturing, where precise flow control is critical, the ability to control the opening and closing of the valve with electrical signals is indispensable.
