Watts 0276250 Valve

Watts 0276250 Valve

The Watts 0276250 is a heavy-duty ASME Section IV certified boiler pressure relief valve designed specifically for high-capacity protection in hot water heating systems and domestic supply boilers. Engineering for critical safety, the Watts 174A-150 features a 1-1/4 inch NPT female inlet and outlet, providing a fixed 150 psi pressure relief setpoint. This model, often referred to by technicians as the 174A-1 1/4-150#, is capable of a massive steam discharge capacity of 6,340,000 BTU/hr, making it the standard choice for larger commercial and industrial hydronic applications as a primary safety relief valve. Built with a rugged bronze body and high-temperature resisting water seal, it isolates the stainless steel spring from the media to prevent corrosion. The non-mechanical seat-to-disc alignment ensures the valve will not stick or freeze, even in systems where sediment might otherwise foul the seat. For pros in the field, the Watts 174A series is the go-to for ensuring system integrity against thermal expansion and runaway firing conditions without the typical mechanical failures found in lower-tier valves.

Key Benefits
  • High BTU Rating: Manages up to 6,340,000 BTU/hr, ensuring compliance for high-capacity boilers.
  • Enhanced Seat Design: The seat is positioned above the drain to prevent water trapping and sediment fouling.
  • Corrosion Resistance: Bronze body construction and stainless steel springs provide longevity in demanding hydronic environments.
  • Reliable Reseating: Features a soft-seated, automatic reseating design for consistent performance after emergency operation.
  • Industry Compliance: Meets ASME Section IV requirements for hot water heating boilers.
Common Questions

What is the maximum temperature rating for this valve?
The Watts 174A is rated for a maximum temperature of 250°F (121°C).

Can I use this valve for potable water system pressure control?
No, this specific model (0276250) is a non-lead-free bronze valve intended for closed-loop heating or non-potable domestic supply boiler applications. For potable water, you must use the lead-free (LF) version.

How should the discharge line be oriented for this 1-1/4" valve?
The discharge line must match the 1-1/4" outlet size exactly, pitch downward to a safe drainage point, and terminate at least 6 inches above the floor drain to allow for visual inspection.
