34 105 177000Btu Relief Vl For Watts Part# 274686

A pressure relief valve made especially for industrial heating systems like boilers is the Watts 274686. It protects the system against pressure builds up that might exceed safe thresholds and result in damage or even explosions. When operating pressure is normal, the valve stays closed. To avoid harmful pressure building, the valve automatically opens and releases extra hot water or steam if the pressure rises beyond the predetermined limit, which in this case is 105 pounds per square inch. This guards against expensive damage to pipelines, boilers, and other equipment. The valve's highest heat-handling capability, indicated by the 1,770,000 BTU rating, guarantees that it can withstand the high heat output of industrial boilers. The pipe connection diameter that it is compatible with is indicated by the 3/4-inch size.
