Watts 0163765 Valve
The Watts 0163765 is a professional-grade 40XL-7-150 series automatic reseating temperature and pressure relief valve, engineered for high-output commercial water heater applications. Featuring a rugged bronze body with a 1-inch MNPT inlet and FNPT outlet, this valve provides critical safety protection for large-scale hot water supply tanks. Designed with a massive 2,134,000 BTU steam discharge capacity, it ensures reliable ASME rated and CSA listed performance under extreme conditions. The 7-inch extension thermostat is equipped with a thermo-bonded coating to prevent mineral buildup, ensuring accurate thermal sensing within the top of the tank. Technical features include tamper-resistant bonnet screws, a durable test lever for manual diagnostics, and a non-mechanical seat-to-disc alignment for consistent sealing at a 150 PSI pressure set point. This non-potable valve is a field-proven solution for contractors needing high-capacity T&P valves for industrial boilers and secondary heating loops.
Key Benefits- High BTU Rating: Certified steam discharge capacity of 2,134,000 BTU/hr accommodates large commercial storage tanks.
- Automatic Reseating: Relieves thermal expansion and excess pressure, then automatically reseats to prevent continuous water loss.
- Corrosion Resistance: Bronze body construction and coated probe withstand harsh water conditions and high temperatures up to 210°F.
- Precision Sensing: The 7-inch extension probe allows for accurate temperature monitoring deep within the hot water outlet flow.
- Code Compliance: Meets ANSI Z21.22 standards and is ASME Section IV rated for safety-critical installations.
Is this valve suitable for potable drinking water systems?
No, the Watts 0163765 is made of standard bronze and does not comply with lead-free mandates for potable water. It is intended for non-potable commercial applications only.
What is the difference between the 40L and 40XL models?
The 40XL model utilizes an extension thermostat, which is necessary when the valve is installed in the hot water outlet piping rather than directly in the tank tapping, ensuring the probe reaches the hottest water area.
Can the pressure setting be adjusted in the field?
No, these valves are factory-set at 150 PSI. Field adjustments should not be attempted as they can compromise the safety vacuum and pressure relief calibrations.
