Watts 0259705 Valve
The Watts 0259705 is a high-capacity 1 inch temperature and pressure relief valve engineered for commercial water heating systems and storage tanks. This Series 140X valve is designed to provide automatic protection against excessive thermal expansion and pressure spikes. Featuring a bronze body construction and an extension thermostat with a 6-inch probe, it ensures accurate sensing of tank temperatures up to 210°F. The unit is ASME rated and CSA listed, delivering a steam discharge capacity of 670,000 BTU/hr. The 1" FNPT inlet and outlet allow for straight-line installation on heavy-duty commercial heaters where high-volume relief is required. A stainless steel thermostat tube and non-mechanical seat-to-disc alignment provide reliable automatic reseating after emergency discharge. To maintain compliance with ANSI Z21.22 and ASME Section IV standards, this valve should be inspected regularly using the integrated test lever. Note that this non-lead-free model is specific to non-potable water applications in jurisdictions where the Safe Drinking Water Act (SDWA) is enforced.
Key Benefits:
- High Discharge Capacity: Certified for 670,000 BTU/hr to handle commercial water heater emergency relief requirements.
- Durable Construction: Heavy-duty bronze body resists corrosive conditions and ensures long-term performance in industrial environments.
- Precision Sensing: The 6-inch extension thermostat reaches deep into the hot water outlet for highly accurate temperature monitoring.
- Standardized Fit: 1" FNPT threaded connections provide broad compatibility with standard commercial boiler and tank tappings.
- Fail-Safe Design: Automatic reseating feature prevents continuous water loss after a temporary pressure or temperature surge.
Common Questions:
What is the set pressure for this Watts relief valve?
The Watts 0259705 is factory set to open at 150 PSI. It is designed to prevent domestic and commercial water heaters from exceeding their safe working pressure limits during thermal expansion.
Can this valve be used for potable water systems?
This specific model is a 140X-6 and typically does not meet the "Lead Free" requirements of the Safe Drinking Water Act. It is primarily utilized in commercial hot water heating applications and non-potable closed-loop systems.
Where should the 140X series thermostat be installed?
The 140X extension thermostat is designed for installation in the hot water outlet piping within the allowable distance from the top of the tank, ensuring the 6-inch probe is submerged in the hottest water zone.
