China has emerged as one of the leading manufacturers of solenoid valves globally, with a strong presence in various industries such as automation, HVAC, fluid control, and even home appliances. Among the many types of solenoid valves produced, the normally open solenoid valve (NO solenoid valve) stands out for its unique functionality and widespread application. This article explores the key players in the Chinese solenoid valve market, highlighting their products, advantages, and the role of Chinese manufacturers in driving technological innovation in the fluid control industry.
What is a Normally Open Solenoid Valve? A normally open solenoid valve is a type of valve that remains open when no electrical current is applied to its solenoid. In other words, the valve stays in its open position by default, allowing fluid or gas to flow through it. When electrical power is supplied, the solenoid energizes the valve and closes it, cutting off the flow of the medium. This design makes the normally open solenoid valve ideal for applications where the default state should be open, and only specific triggering events are required to stop the flow. Commonly used in industries like automation, water treatment, gas supply, and air conditioning systems, NO solenoid valves are highly reliable and efficient. They offer a simple solution to control the flow of liquids, gases, and even vacuum systems. These valves are often chosen for their durability and ease of installation in a wide range of industrial applications.
