Watts 0256661 Valve
When your commercial water heating system requires high-capacity protection, the Watts 0256661 Valve (Series 140S) is the industrial standard for 1-inch Temperature and Pressure Relief Valves. This heavy-duty automatic reseating valve is specifically designed for storage tanks and boilers, featuring an ASME pressure steam rating of 3,085,000 BTU/hr. Built with a rugged bronze body and 1" NPT female inlet/outlet connections, it ensures a secure, leak-free integration into your main header or tank tapping.
The Watts 140S-3-1-150 is equipped with a 3-inch stainless steel thermostat probe that provides precise thermal response, set to trip at 210°F. For pressure management, this unit is factory-set at 150 PSI to prevent catastrophic vessel failure. To ensure field integrity, it includes tamper-resistant bonnet screws and a reinforced test lever for manual diagnostic checks. This T&P relief valve is essential for contractors maintaining large-scale domestic hot water systems that demand high BTU discharge capacities and non-mechanical seat-to-disc alignment for consistent performance.
Key Benefits for Technicians- High BTU Discharge Capacity: Certified at 3,085,000 BTU/hr (ASME) to handle high-output commercial boilers.
- Durable Bronze Construction: Resists corrosive water conditions to maintain structural integrity in demanding HVACR environments.
- 3-Inch Thermostat Probe: Facilitates accurate temperature sensing by extending directly into the heat zone of the tank.
- Automatic Reseating: Minimizes water loss and system downtime by closing securely after a pressure or temperature relief event.
- Industry Compliance: Meets ASME Section IV and CSA requirements for commercial hot water supply.
Is the Watts 0256661 suitable for residential water heaters?
While functional, this 1-inch valve is specifically engineered for commercial applications due to its high BTU rating and larger connection size. Standard residential tanks typically utilize 3/4-inch valves with significantly lower discharge capacities.
Can I install this valve in any orientation?
For optimal safety and performance, the valve should be installed so that the temperature sensing element is immersed in the hottest water within the top 6 inches of the tank. Always ensure the discharge line is pitched for positive drainage.
Why is the 140S model preferred over the 140X?
The 140S features a short thermostat designed for direct installation into tank tappings, whereas the 140X uses an extended thermostat for mounting in the hot water outlet piping. Choice depends entirely on your specific tank port configuration.
