Watts 0275264 Valve

Watts 0275264 Valve

The Watts 0275264 (Series 174A) is a high-capacity boiler pressure relief valve engineered for critical overpressure protection in hot water heating and domestic supply systems. This 1-inch FNPT valve is factory-set at 100 PSI and features a massive steam discharge capacity of 2,635,000 BTU/HR, making it a reliable choice for commercial and heavy residential hydronic applications. Built with a rugged bronze body construction and a heavy-duty stainless steel spring, the unit is designed to resist corrosive water conditions and prevent the "sticking and freezing" often seen in lower-grade components. The non-metallic disc-to-metal seating ensures a positive seal and automatic reseating after a pressure event. As an ASME Section IV certified safety device, this valve utilizes an "above-drain" seat design to ensure that sediment cannot collect and foul the internal mechanism. This specific model is intended for non-potable water systems, providing emergency relief for boilers operating at temperatures up to 250°F.

Key Benefits
  • High BTU Capacity: Rated for up to 2,635,000 BTU/HR to handle high-output boiler systems safely.
  • Corrosion Resistance: Features bronze body construction and a stainless steel spring to withstand harsh hydronic environments.
  • Reliable Reseating: The soft seated design and non-mechanical alignment prevent the valve from sticking or failing to close after discharge.
  • ASME Certified: Tested and rated by the National Board to meet strictly enforced ASME Section IV safety standards.
  • Sediment Protection: The raised seat design ensures water and debris are not trapped, maintaining a clear path for emergency discharge.
Common Questions

What is the proper orientation for installing a Watts 174A relief valve?
Technicians should install the valve in either a vertical or horizontal position, ensuring the discharge pipe is the same diameter as the valve outlet and pitches downward to a safe floor drain to prevent air pockets or water accumulation.

Can this valve be used as a primary temperature control?
No. This is an emergency safety relief valve designed solely for overpressure protection. It should never be used as an operating control to regulate system temperature or standard working pressure.

Is the Watts 0275264 compliant with lead-free standards for drinking water?
This specific 174A model is not lead-free and is strictly for non-potable hot water heating applications. For potable water systems, you must utilize the Watts LF174A series.
