Watts 0121585 Regulator
The Watts 0121585 is a professional-grade 1" LFN240X-6 automatic reseating temperature and pressure relief valve designed specifically for large commercial water heaters and domestic hot water supply tanks. Engineered with a lead-free copper silicon alloy body, this valve meets stringent ANSI Z21.22 and ASME Section IV requirements for high-capacity protection. This specific model is factory set for 100 PSI pressure relief and 210°F temperature relief, utilizing a 6-inch stainless steel thermostat probe to ensure precise thermal sensing within the tank. As a veteran-preferred solution, the LFN240X series features tamper-resistant bonnet screws and a non-mechanical seat-to-disc alignment to prevent leaks and ensure reliable operation under extreme conditions. The inclusion of the SentryPlus Alert flood sensor allows contractors to integrate this safety device directly into a building automation system (BAS) via appropriate connection kits, providing proactive monitoring of unwanted discharge events. Whether you are performing a new installation or a critical maintenance replacement, the Watts LFN240X-6 relief valve delivers the high-volume BTU discharge capacity required for heavy-duty HVACR applications.
- Lead-Free Construction: Complies with all lead-free installation requirements for potable water systems.
- Automatic Reseating: Features an automatic reseating mechanism that independently resets after a pressure or temperature relief event.
- High BTU Capacity: Designed for commercial systems where standard residential valves fall short on discharge volume.
- Integrated Monitoring: Packaged with a SentryPlus Alert discharge line flood sensor for smart facility connectivity.
- Corrosion Resistance: Features a thermo-bonded coated thermostat probe to retard mineral deposit accumulation and extend service life.
Common Questions
What is the relief capacity of this valve?
The Watts LFN240X-6 is designed for high-capacity applications, typically rated up to 730,000 BTU/hr or higher depending on the specific CSA/ASME certification for your regional code requirements. Always verify the BTU rating on the nameplate matches your heater’s input.
How do I activate the flood sensor alert system?
The included SentryPlus Alert sensor requires a separate activation kit to function. This kit allows the valve to communicate with building management systems (BMS) through cellular or Wi-Fi gateways to provide real-time notification of discharge.
Can this valve be installed in any orientation?
For proper operation, the valve should be installed directly in the water heater’s tank tapping or in the hot water outlet line. The thermostat probe must be immersed in the water within the top 6 inches of the tank to accurately sense temperature conditions.
