Watts 0274426 3/4" Female NPT 30 to 150 PSI Bronze Boiler Pressure Relief Valve

This 3/4 inch 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 consists of a bronze 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. It is designed for emergency safety relief, not as an operating control. The pressure relief is set at 33 psi (228 kPa) with corresponding high pressure ratings up to 695,000 BTU/hr.695,000 BTU/hr.

Features:

Water seal of high temperature resisting material isolates spring working parts from water during relief
Non mechanical seat-to-disc alignment will not stick or freeze
Water can't be trapped and sediment can't foul seat
Bronze body safety relief valves for pressure protection only of all types of hot water heating boiler equipment
