A safety valve is a valve that acts as a fail-safe. An example of safety valve is a pressure relief
valve (PRV), which automatically releases a substance from a boiler, pressure vessel, or
other system, when the pressure or temperature exceeds preset limits. Pilot-operated relief
valves are a specialized type of pressure safety valve. A leak tight, lower cost, single emergency
use option would be a rupture disk.
Safety valves were first developed for use on steam boilers during the Industrial Revolution. Early
boilers operating without them were prone to explosion unless carefully operated.
