Watts 0275054 Relief Valve

The Watts 0275054 is a heavy-duty 174A-1-50 boiler pressure relief valve engineered for critical overpressure protection in large-scale hydronic heating and domestic supply boiler systems. Featuring a rugged bronze body and a 1-inch NPT female threaded inlet and outlet, this ASME Section IV rated safety valve is set to trip at 50 PSI. With a massive discharge capacity of 1,470,000 BTU/hr, it is built to handle the rigorous demands of commercial mechanical rooms. The internal design utilizes a non-metallic disc-to-metal seating and a stainless steel spring to prevent sticking and freezing, even in corrosive water conditions. A key technical advantage is the raised seat, which ensures water and sediment cannot become trapped, maintaining reliable automatic reseating after a pressure event. This valve is strictly for emergency safety relief and should not be utilized as an operating control.

Key Benefits

• High BTU Capacity: Rated for 1,470,000 BTU/hr to ensure adequate venting for high-output boiler systems.
• Sediment Resistance: The above-drain seat design prevents debris from fouling the seal, ensuring a tight closure every time.
• Durable Construction: The bronze body and stainless steel spring provide superior corrosion resistance and long-term mechanical reliability.
• Serviceable Design: Includes a standard test lever for manual inspection and verification of the relief mechanism.

Common Questions

• Is the Watts 0275054 lead-free? No, this model is a standard bronze relief valve intended for non-potable hot water heating applications.
• What is the maximum operating temperature? This 174A series valve is rated for fluid temperatures up to 250°F.
• Can this valve be used for steam applications? This specific model is designed for hot water heating boilers and domestic supply systems, not for steam service.
