Weil McLain 633-900-102 T-Stat

The Honeywell Home AM101-US-1LF is a lead-free proportional thermostatic mixing valve designed for point-of-source applications where precise temperature control and scald protection are critical. Featuring a Union Sweat connection, this ASSE 1017 certified valve provides a stable mixed water temperature across a wide range of flow rates, making it an essential component for high-efficiency domestic hot water loops. The Teflon coating on the internal shuttle prevents mineral buildup and scaling, ensuring long-term reliability in hard water conditions. With a cv rating of 3.9 and a temperature adjustment range of 70°F to 145°F, this unit allows for higher water heater storage temperatures to kill Legionella bacteria while delivering safe, tempered water to the fixtures. The lockable handwheel prevents unauthorized adjustments, maintaining system compliance for commercial plumbing installations and residential code requirements.

• Scald Protection: Precision thermostatic element maintains discharge temperature within +/- 3°F.
• Corrosion Resistance: Teflon-coated brass construction reduces maintenance intervals and prevents sticking.
• Increased Capacity: Allows for higher tank temperatures, effectively increasing the usable hot water volume.
• Simplified Installation: Union Sweat fittings allow for easy serviceability and removal without cutting pipe.
