An automatic release mechanism, a safety valve discharges substances from boilers, pressure vessels or systems when their pressure or temperature surpass predetermined thresholds. It forms part of a suite of pressure safety valves and pressure relief valves, which encompass relief valves, safety relief valves, pilot-operated relief valves, low-pressure safety valves, and vacuum pressure safety valves. The Industrial Revolution era saw the initial implementation of safety valves on steam boilers.
