Watts 0559105 Valve
The Watts 0559105 (Model LF1170-M2-US) is a high-performance 1 inch thermostatic mixing valve engineered for precision temperature regulation in domestic hot water systems and radiant heating applications. Featuring a lead-free cast copper silicon alloy body, this valve utilizes a solid wax hydraulic principle thermostat to maintain consistent discharge temperatures despite fluctuations in supply pressure or temperature. The double throttling design provides a rapid response to temperature changes, safely restricting mixed water to a drip if the cold water supply is lost to prevent scalding. This ASSE 1017 listed valve is rated for flow rates from 0.5 to 23 GPM and handles a maximum pressure of 150 psi. Targeted for point-of-source installation, it includes union solder connections for simplified maintenance, along with integral check valves and filter gaskets to eliminate cross-flow. The adjustable temperature dial is protected by a locking adjustment cap, ensuring setpoints between 90°F and 160°F remain secure in commercial or residential mechanical rooms.
Key Benefits- Advanced Thermal Actuation: The solid wax thermostat ensures highly accurate mixing and rapid response to inlet changes.
- Enhanced Safety Logic: Designed to provide a "fail-safe" restricted flow if the cold water supply is compromised.
- System Protection: Built-in integral check valves and filter washers prevent cross-flow and protect internal components from debris.
- Lead-Free Compliance: Constructed from copper silicon alloy to meet strict potable water safety regulations.
- Application Versatility: Ideal for radiant floor heating and large-scale domestic hot water distribution.
Is the Watts LF1170-US suitable for point-of-use applications?
No, this model is ASSE 1017 listed for point-of-source (water heater or boiler) applications. For point-of-use protection at fixtures, an ASSE 1070 listed valve is required.
What is the maximum operating temperature for this mixing valve?
The valve can handle a maximum hot water inlet temperature of 200°F, with a field-adjustable mixed outlet range of 90°F to 160°F.
Can this valve be installed in any orientation?
Yes, the LF1170-M2-US can be installed in various orientations, provided the flow directions indicated on the valve body are strictly followed for the hot and cold inlets.
