Watts 0276980 Valve
The Watts 0276980 is a high-capacity boiler pressure relief valve engineered for industrial and commercial hot water heating systems. Part of the Watts Series 174A, this 1-1/2 inch NPT valve is ASME Section IV certified and specifically designed to provide emergency safety relief for high-output equipment. With a fixed pressure setting of 125 psi, it delivers a massive steam discharge capacity of 6,460,000 BTU/hr, ensuring system protection during runaway firing or thermal expansion. The heavy-duty bronze body construction and stainless steel spring are built to withstand the rigors of hydronic service, while the non-metallic disc-to-metal seating prevents sticking and freezing over long-term operation. As a veteran-grade ASME relief valve, it features an above-drain seat design that prevents sediment buildup and prevents water from being trapped, ensuring consistent performance in high-demand environments. This hot water safety valve is ideal for contractors requiring precise pressure management in non-potable domestic supply and space heating boiler applications.
Key Benefits- Maximum Discharge Capacity: Rated for up to 6,460,000 BTU/hr to handle high-output commercial boilers.
- ASME Rated Safety: Certified under ASME Section IV for reliable pressure protection in industrial systems.
- Sediment Resistance: The raised seat design ensures water and debris do not collect around the seal, reducing the risk of fouling.
- Durable Seating: Features non-metallic disc-to-metal seating to prevent the valve from sticking or freezing even after long periods of inactivity.
- Field Testing Ready: Equipped with a standard test lever for manual inspection and mandatory annual maintenance checks.
Is the Watts 0276980 suitable for potable water systems?
No, this model is designed for non-potable hot water heating and boiler applications. It does not meet lead-free requirements for drinking water systems.
What is the maximum operating temperature for this relief valve?
This valve is rated for a maximum temperature of 250°F (121°C), making it suitable for high-temperature hydronic loops.
Does this valve come with a flood sensor?
While many modern Series 174A valves are packaged with SentryPlus Alert sensors, the 0276980 specifically focuses on the 125 psi mechanical relief functions; always verify if your specific build includes the electronic sensor kit.
