2019-7-8 · 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

Top Ten Boiler and Combustion Safety Issues to Avoid

These are called safety shutoff valves. Larger gas trains require dual safety shutoff valves in series. Some are also assembled into a piping arrangement that includes a vent between them for added safety. The vent and its piping are provided to allow any leakage past a shutoff valve to go outside the building when the equipment is off.
