A Normally Open Solenoid Valve (NO Solenoid Valve) is a type of valve used in fluid control systems that operates automatically through the use of an electrical solenoid coil. These valves are an essential part of various applications, particularly in industries like automation, irrigation, water treatment, and fluid transportation. Their unique design and functionality enable them to control the flow of fluids with high precision, offering both efficiency and safety in many systems. In this article, we will explore the working principle, features, and common applications of Normally Open Solenoid Valves.
What is a Normally Open Solenoid Valve? A Normally Open Solenoid Valve is designed in such a way that, in its default state (when the solenoid coil is not energized), the valve remains open. This allows the passage of fluid through the valve. When the solenoid coil is powered, the valve is activated and moves into the closed position, restricting the fluid flow. The ability to stay open without electricity makes these valves useful in specific applications where the flow of fluid must be uninterrupted under normal conditions, and only stopped when required by an external electrical signal.
