Solenoid valves are essential components in many industrial and commercial applications. Among them, normally open solenoid valves play a vital role by allowing fluid or gas to flow when no electrical power is applied. When energized, the solenoid coil closes the valve to halt the flow. These valves are widely used in systems ranging from HVAC and irrigation to water treatment and industrial automation. As the demand for high-quality solenoid valves continues to grow, China normally open solenoid valve manufacturers are leading the way in offering innovative, cost-effective, and reliable solutions for businesses worldwide.
Understanding Normally Open Solenoid Valves A solenoid valve is an electromechanical device that controls the flow of fluids or gases. It consists of a solenoid coil, a plunger, and a valve body. The solenoid coil, when energized, creates a magnetic field that moves the plunger, changing the valve’s position. In the case of a normally open solenoid valve, the valve remains in the open position by default, allowing flow. When the solenoid is energized, the valve closes, stopping the flow. This type of valve is ideal for systems that require automatic flow control in the absence of an electric signal. Some of the primary applications include irrigation systems, air compressors, cooling systems, and water treatment plants, among others.
