Watts 0163725 Valve

Watts 0163725 Valve

The Watts 0163725 is a high-capacity commercial temperature and pressure relief valve designed specifically for large-scale hot water heaters and supply tanks. This 1-inch Watts 40XL-4-150 unit features a 4-inch extension thermostat with a specialized thermo-bonded coating to minimize mineral buildup and ensure consistent thermal response in rigorous environments. Rated for a steam discharge capacity of 2,134,000 BTU/hr (ASME), it provides essential protection against over-temperature and over-pressure events.

Engineered for professional contractors, this ASME rated relief valve utilizes a bronze body with 1" NPT male inlet and female outlet connections. The automatic reseating design, combined with a non-mechanical seat-to-disc alignment, ensures reliable performance and a tight seal after operation. The valve is set to trip at 150 psi or 210°F, meeting stringent ANSI Z21.22 listing requirements for commercial thermal safety. For technicians installing in tight clearances, the extension probe allows for accurate sensing when mounted in the hot water outlet pipe or dedicated tank tappings.

Key Benefits:
  • High BTU Capacity: Rated for up to 2,134,000 BTU/hr, making it suitable for large commercial boilers and storage tanks.
  • Corrosion Resistance: Features a thermo-bonded coated thermostat that resists scale and calcification.
  • Robust Construction: Heavy-duty bronze body with tamper-resistant bonnet screws for secure, long-term field service.
  • Reliable Reseating: Automatic reseating mechanism reduces downtime and manual intervention after a pressure spike.
Common Questions:

Is this valve suitable for potable water systems?
This specific model (0163725) is intended for industrial and non-potable commercial applications. For systems requiring lead-free compliance, refer to the LF40XL series.

Where should the 4-inch probe be positioned for accurate sensing?
The thermostat must be fully immersed in the water within the top 6 inches of the tank to ensure the 210°F thermal relief functions correctly.

What causes a T&P valve to drip under normal operation?
Weeping is often caused by thermal expansion in a closed system. While the valve is performing its job by relieving excess pressure, installing a thermal expansion tank is the recommended way to manage this without stressing the relief valve seat.
