Product Details

Watts 0121479

This 3/4'' lead free boiler pressure relief valve is used in hot water heating and domestic supply boiler applications to protect against excessive pressures on all types of hot water heating supply boiler equipment. It is designed for emergency safety relief, not as an operating control. It consists of a lead free body construction with NPT threaded female inlet and NPT threaded female outlet (drain) connections, non-metallic disc-to-metal seating, stainless steel spring, and test lever. It resists corrosive water conditions, sticking and freezing, and prevents water and sediment from being trapped in the seat. The pressure setting is 125 psi (862 kPa), with corresponding ratings of 2,070,000 BTU/hr.
