Watts 0121601 Valve
The Watts 0121601 (Model LF340-3-125) is a high-capacity, 1.5-inch lead free temperature and pressure relief valve designed specifically for large-scale commercial water heaters and domestic hot water storage tanks. Engineered to manage an impressive steam discharge capacity of 5,403,000 BTU/hr, this valve is a critical fail-safe for preventing catastrophic system failure due to thermal expansion or pressure spikes. It features a rugged lead free copper silicon alloy body and a 3-inch stainless steel thermostat tube with a specialized thermo-bonded coating to prevent mineral accumulation and ensure consistent thermal response at the 210°F setpoint. With a factory-set pressure relief of 125 PSI and an automatic re-seating design, this ASME rated T&P valve eliminates the need for manual replacement after minor discharge events. The ANSI Z21.22 certified construction incorporates tamper-resistant bonnet screws and a non-mechanical seat-to-disc alignment, providing technicians with a reliable, code-compliant solution for high-demand hydronic and potable water applications.
Key Benefits
- High Relief Capacity: Massive 5.4M BTU/hr rating handles large commercial boiler and storage tank requirements.
- Lead Free Compliance: Constructed from copper silicon alloy to meet stringent potable water safety standards.
- Advanced Thermostat: Features a 3" stainless steel probe with thermo-bonded coating to resist scale and corrosion.
- Automatic Re-seating: Fully automatic operation allows the valve to close independently after satisfying temperature or pressure demands.
- System Integration: Packaged with a SentryPlus Alert discharge line flood sensor for remote monitoring via building automation systems.
Common Questions
Is the Watts LF340-3-125 compatible with both top and side tank tappings?
Yes, this 1.5" valve is designed for direct installation into tank tappings, but always ensure the thermostat probe is fully immersed in the top 6 inches of the tank water for accurate temperature sensing.
What is the difference between the LF340 and the standard 340 series?
The "LF" prefix indicates lead free construction, making the 0121601 compliant with state and federal regulations for systems providing water for human consumption.
Does this valve require a specific discharge line size?
Per code and manufacturer specifications, the discharge line must be the same size as the valve outlet (1.5" NPT) and must pitch downward to allow for complete drainage.
