WATTS® Pressure Relief Valve, 174A Series, 3/4 in Nominal, FNPT Connection, 100 psi, Lever Actuator, Stainless Steel Trim, Bronze Body, 250 deg F, 2-3/4 in Length, 4-1/2 in Height

Series 174A boiler pressure relief valves are 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. They have 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. Series 174A resists corrosive water conditions, sticking and freezing and it prevents water and sediment from being trapped in the seat. It is designed for emergency safety relief and shall not be used as an operating control. Standard pressure setting, 30 psi (206.9 kPa). Pressure range in 5 psi (34.5 kPa) increments from 30 to 150 psi (2 to 10 bar) with corresponding high ratings from 650000 to 14370000 Btu/hr.
