understanding normally open solenoid valve: function, applications, and benefits
Release time:2025-12-26 15:15:35
In the world of automation and fluid control, solenoid valves are indispensable components. Among various types, the Normally Open (NO) solenoid valve plays a crucial role in managing the flow of fluids and gases in numerous applications. This article delves into the functionality, applications, benefits, and considerations associated with Normally Open solenoid valves.
What is a Normally Open Solenoid Valve?
A Normally Open solenoid valve is a type of electromechanical valve that remains open when no electrical power is applied. In other words, it allows fluid or gas to flow through it by default. When an electrical signal is sent to the solenoid coil, it activates the electromagnet, which pulls a plunger or armature, causing the valve to close. This operation reverses when the electrical signal is removed—the valve returns to its open position due to the force of a spring or gravity.
Functionality of Normally Open Solenoid Valves
The fundamental principle behind NO solenoid valves is the conversion of electrical energy into mechanical motion. When voltage is applied to the solenoid coil, a magnetic field is created, attracting the armature to seal the valve. The valve then shuts off the flow of fluid or gas. These valves can operate with various types of fluids, including water, air, and other gases and liquids, making them versatile components in many systems.
