  • Safety valve - Wikipedia

    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 Learn More

  • OBSERVING BOILER SAFETY RULES - idc-online.com

    NEVER increase the setting of a safety valve without authority. Serious accidents have occurred from failure to observe this rule. ALWAYS consult an authorized boiler inspector and accept his or her recommendations before increasing the safety-valve pressure setting. NEVER change adjustments of a safety valve more than 10 percent. Proper Learn More
