A safety valve is used to automatically release material in order to change a system’s temperature or internal

pressure.

These mechanisms are very common on devices that use heated liquid, particularly water, to create mechanical energy.

The systems using safety valve usually have portions with extreme temperature,pressure or circulating liquid.
Devices such as steam boilers, hot water heaters and refrigeration systems all use safety valves as a method of keeping them from exploding.

When the pressure rises above a prescribed amount or temperature differences begin to endanger the system’s physical structure, the safety valve will trigger to equalize the system.
