The Difference Between Normally Closed Valves and Normally Open Valves

Normally Closed Valves
Normally Closed Valves and Normally Open ValvesNormally closed valves are designed to block flow through the valve and are commonly used for emergency safety. During usual operation, these devices use a spring to remain closed. The valve will open when the system begins to experience overpressure to ensure safety. Once pressure begins to normalize, it will automatically close.

Solenoid valves can also be normally closed. A solenoid valve is an electromechanical device that controls the flow of liquid or gas through a system. Normally closed solenoid valves include a plunger that remains in a closed position when the system is running smoothly, like pressure relief valves.

Normally closed solenoid valves also include a coil that, when powered, will cause the plunger to open and allow liquid or gas to pass through the valve.

Normally Open Valves
Normally open valves are also used as safety devices. However, unlike normally closed valves, these parts work to maintain low pressure in a system. Normally open valves are designed to allow liquid or gas to flow through in usual circumstances. As the system builds pressure, they will begin to shut in order reduce and regulate pressure levels. In some extreme overpressure situations, they will close almost entirely.

Normally Closed Valves and Normally Open ValvesThere are normally open solenoid valves as well. These devices will remain open until power is sent to the coil and signals the plunger to close.
