Normally open solenoid valves are vital components in fluid control systems. These valves are designed to remain open under standard conditions, allowing fluids or gases to pass through freely. When activated by an electric current, the valve closes, stopping the flow. This operation is crucial for applications where it’s essential to control the flow of air, water, oil, or other fluids in various systems, such as pneumatic, hydraulic, and HVAC systems.

    Unlike normally closed solenoid valves, which block flow in their default state, normally open valves are preferred in certain setups where a system needs to maintain an open path until an external signal directs otherwise. These valves are used in a variety of industries, including automation, manufacturing, and irrigation.
