A normally open solenoid valve is an essential component in fluid control systems, widely used in various industries to regulate the flow of liquids and gases. This type of valve operates by using an electric solenoid to control the opening and closing mechanism, and its default state is open when no electrical current is applied. This characteristic makes it ideal for applications where fluid flow is required to be maintained in the event of power failure, thus ensuring safety and efficiency in critical operations.

    At its core, a normally open solenoid valve comprises a coil, a plunger, and a spring. The coil generates a magnetic field when electric current is passed through it, attracting the plunger to close the valve. When the power supply is cut off, the spring pushes the plunger back, opening the valve and allowing fluid to flow freely. These valves are known for their quick response times and ability to operate in both low and high-pressure environments. Their ability to function in extreme conditions makes them versatile and reliable in industries such as automotive, agriculture, HVAC systems, and more.
