A Normally Open Solenoid Valve (NO solenoid valve) is a critical component used in various fluid control systems, such as in automation, HVAC, irrigation, and industrial equipment. It plays an essential role in regulating the flow of liquids or gases through pipes, making it one of the most widely used devices in modern mechanical and electrical systems. To better understand its significance, it’s important to explore how it works, its applications, and the benefits it brings to different industries.
What is a Normally Open Solenoid Valve? A Normally Open (NO) Solenoid Valve is a type of valve that controls the flow of fluid or gas by using an electromagnet (solenoid) to open or close the valve. In the “normally open” configuration, the valve remains open when the solenoid is not energized. This means that, in its default state, the flow path remains unobstructed, and fluid can pass freely through the valve. Once the solenoid is energized (through the application of electrical current), it pulls a plunger or diaphragm that either closes the valve or changes the flow direction, depending on the valve design.
