normally open solenoid valve: a key component in fluid control systems
Release time:2025-04-25 18:43:01
A solenoid valve is an essential component in fluid control systems, serving as an automatic device for controlling the flow of liquids or gases. Among the various types of solenoid valves, the Normally Open (NO) solenoid valve plays a critical role in a variety of applications where precise and automated flow control is required. This article explores the function, applications, and advantages of Normally Open solenoid valves, with a special focus on Meishuo, a leading brand in the industry.
What is a Normally Open Solenoid Valve?
A Normally Open solenoid valve is a valve that remains open when there is no electrical current applied to it. In other words, the valve's internal mechanism stays open to allow fluid flow until the solenoid is energized. When the solenoid is powered, the valve closes, stopping the fluid flow. This configuration is opposite to the Normally Closed (NC) solenoid valve, which remains closed when de-energized and opens when energized.
The solenoid itself consists of a coil of wire through which an electrical current passes to generate a magnetic field. This magnetic field then activates a plunger or armature that either opens or closes the valve depending on the design. For a Normally Open solenoid valve, the solenoid’s activation closes the valve and stops the flow of fluids, making it highly effective in systems where flow is only needed when a specific condition is met.
