Watts 0559103 Hot Water Temperature Control Valve 3/4" LF1170M2-US

Watts Series LF1170 & LFL1170 Hot Water Temperature Control Valves  Series LF1170, LFL1170 Hot Water Temperature Control Valves are specifically designed for mixing hot and cold water on hot water supply systems. They can be used for a variety of applications to reduce the temperature of the hot water from the system and are ideal for radiant heat applications. This series features a “double throttling” design which combines the control of the hot and cold water to provide a sensitive response to changes in water temperature passing through the mixing chamber. The LF1170M2 can be set to any temperature between 90°F and 160°F (60°F and 120°F for model LFL1170M2) with flow rates as low as 0.5 gpm and as high as 23 gpm (refer to capacity chart on the back). The superior flow characteristics of this valve provide accurate temperature control to the requirements of ASSE 1017** across the rated flow range. The LF1170M2 and LFL1170M2 feature Lead Free* construction to comply with Lead Free* installation requirements. These valves also provide additional safety as they restrict mixed water out to a drip upon loss of cold water supply to the valve. As an added feature, the LF1170M2 and LFL1170M2 incorporate integral check valves and filter washers in both the hot and cold water inlets to protect against cross flow. Available with threaded (-UT), solder (-US), Pex (-PEX), Quick-Connect (-QC) or CPVC (-CPVC) connections or w/press****. Features:   Lead Free* cast copper silicon alloy body construction Solid wax hydraulic principle thermostat assures dependable mixing of hot and cold water Thermostat controls both hot and cold water Models available with solder, thread, Pex, Quick-Connect cpvc end connections or w/press**** Integral filter washers and check valves Adjustment cap with locking feature ASSE 1017 listed**, IAPMO cUPC, and NSF61-G
