normally open solenoid valve: an essential component in modern fluid control systems
Release time:2025-06-09 17:14:13
Normally Open (NO) solenoid valves are integral to a wide variety of fluid control systems. These valves play a crucial role in regulating the flow of gases and liquids in industries ranging from automotive to manufacturing, medical, and even home appliances. A Normally Open solenoid valve allows fluid to flow freely when it is not energized and shuts off when activated. This functionality makes it an ideal choice for systems that require the flow of fluid to stop under specific conditions, such as safety, emergency shut-off, or controlling pressure.
One notable brand in the solenoid valve market is Meishuo, which has gained recognition for producing reliable and high-quality solenoid valves. Meishuo’s Normally Open solenoid valves are built with precision engineering to ensure efficient operation and long-term durability. Their products cater to diverse industries, offering customized solutions to meet specific customer needs.
How Does a Normally Open Solenoid Valve Work?
A Normally Open solenoid valve functions based on the principle of electromagnetism. The valve consists of a coil, a plunger, and a spring. When the solenoid valve is in its default state (unpowered), the plunger is held open by the spring, which allows fluid to flow through the valve. This is the "normally open" position. However, when electrical current is applied to the solenoid, it creates a magnetic field that pulls the plunger against the spring, closing the valve and stopping the flow of fluid. Once the power is turned off, the spring pushes the plunger back into the open position, allowing fluid to flow again.
