Watts Regulators 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.

• Safety relief valves for pressure protection only of all types of hot water heating boiler equipment
• Seat located above drain, water cant be trapped and sediment cant foul seat
• Non-mechanical seat-to-disc alignment will not stick or freeze
• Water seal of high temperature resisting material isolates spring working parts from water during relief
