Watts 0277010 Valve
The Watts 0277010 is a heavy-duty ASME Section IV certified hot water pressure relief valve designed for high-capacity protection in commercial boiler systems and domestic hot water supply applications. Engineered for reliability, the Series 174A features a 1-1/2 inch NPT female inlet and outlet, facilitating a high-volume steam pressure discharge capacity of up to 7,630,000 BTU/hr at a factory-set relief pressure of 150 psi. Its bronze body construction ensures superior resistance to corrosive water conditions, while the non-metallic disc-to-metal seating prevents sticking and freezing even in demanding environments.
For the field technician, the Watts 174A-150 is built with a raised seat located above the drain, ensuring that water and sediment cannot be trapped, which significantly reduces the risk of seat fouling. The non-mechanical seat-to-disc alignment and high-temperature resistant water seal isolate the stainless steel spring from the discharge flow, maintaining consistent performance during emergency relief cycles. This automatic reseating valve is strictly for emergency pressure protection and should not be used as an operating control.
Key Benefits- High BTU Rating: Provides emergency relief for systems up to 7,630,000 BTU/hr.
- Corrosion Resistance: Robust bronze body and stainless steel spring withstand harsh hydronic environments.
- Anti-Foul Design: Raised seat architecture prevents sediment buildup and eliminates sticking.
- ASME Certified: Meets rigorous ASME Section IV safety standards for pressure relief.
- Secure Seating: Non-metallic disc provides a tight seal and reliable automatic reseating.
What is the maximum operating temperature for this valve?
The Watts 0277010 is rated for a maximum temperature of 250°F (121°C), making it suitable for standard hot water heating boilers.
Is this valve compliant for potable water use?
No, this specific model does not meet lead-free requirements and is intended for non-potable hydronic heating and space heating applications only.
How should the discharge line be oriented?
The discharge line must match the 1-1/2 inch outlet size, pitch downward to prevent water traps, and terminate at a safe disposal point according to local plumbing codes.
