Watts 0559115 Temp Valve

The Watts 0559115 is a high-performance 1/2" union solder thermostatic mixing valve from the Series MMV-M1, engineered to maintain precise domestic hot water temperatures between 80°F and 120°F. As the direct updated replacement for the discontinued Watts 0206000, this LFMMVM1-US model features a lead-free cast copper silicon alloy body, ensuring compliance with strict potable water standards. Utilizing a double-throttling design, the thermostatic water mixing valve regulates both hot and cold inlets simultaneously to deliver a stable outlet temperature within ±3°F. It is built for versatility, boasting ASSE 1017, 1069, and 1070 certifications, making it suitable for single-fixture, multi-fixture, and source applications. This Watts mixing valve includes integral check valves and filter washers to prevent cross-flow and protect internal components. With a flow rate range of 0.5 to 12 GPM and a maximum pressure rating of 150 psi, it is the standard choice for contractors requiring reliable scald protection and thermal stability in residential or commercial mechanical systems.

• Precise Thermal Control: Advanced wax hydraulic thermostat manages fluctuations to maintain a set point within +/- 3°F.
• System Protection: Integrated check valves and stainless steel strainers prevent cross-flow and debris-related failures.
• Code Compliance: Triple-listed for ASSE 1017, 1069, and 1070, allowing for legal installation at the source or point-of-use.
• Serviceable Design: Features a locking adjustment cap to prevent unauthorized temperature tampering after commissioning.
• Versatile Compatibility: Designed specifically as the drop-in Watts 0559115 replace 0206000 solution for existing sweat-connection layouts.

Is the Watts 0559115 lead-free?
Yes, this model is constructed from lead-free copper silicon alloy, meeting all current regulations for potable water systems.

Can this valve be used for both a single shower and a whole-home source?
Correct. Because it carries ASSE 1017 and 1070 listings, it is rated for both hot water source and individual fixture applications.

What is the difference between 0559115 and 0206000?
The 0559115 is the updated lead-free version of the 0206000. It maintains the same 1/2" sweat dimensions and performance specs for seamless retrofitting.
