A Safety valve is a valve mechanism for the automatic release of a substance from a boiler, pressure vessel, or other system when the pressure or temperature exceeds preset limits.

 It is part of a bigger set of pressure safety valves (PSV) or pressure relief valves (PRV). The other parts of the set are relief valves, safety relief valves, pilot-operated relief valves, low pressure safety valves, and vacuum pressure safety valves.

 Safety valves were first used on steam boilers during the industrial revolution. Early boilers without them were prone to accidental explosion.
