Watts 174A Hot Water Pressure Relief Valve - 3/4", 150 PSI, 2,445,000 BTU/HR
Note: This item does not comply with the 2014 Lead Free Act. It may not be used in potable water applications as of January 4, 2014.
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. 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. Series 174A 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 and shall not be used as an operating control. Standard Pressure Setting: 30psi (206.9 kPa), Pressure Range: In 5psi (34.5 kPa) increments from 30 to 150psi (2 to 10 bar) with corresponding high ratings from 650,000 to 14,370,000 BTU/hr.
• 150 PSI pressure relief setting, 30 to 150 PSI pressure range.
• Non-mechanical seat to disk alignment will not stick or freeze.
• Seat located above drain; water can't be trapped and sediment can not foul seat.
• Water seal of high temperature resisting material isolated spring working parts from water during relief.
• The WAT174A bronze body construction resists corrosive water conditions of water supplies.
• For California Residents please see Prop 65 Warnings
