Watts LF1170M2-CEF 3/4 - Part of the LF1170 Series
This 3/4 inch lead free hot water control valve is designed for installation on water heating equipment to provide tempered water to point-of-use fixtures and is ideal for radiant heat applications. The double throttling design combines hot and cold water control for a sensitive response to water temperature changes in the mixing chamber. It consists of a lead free brass body, cold expansion fitting (CEF/PEX F1960) end connections for PEX-a tubing, solid wax hydraulic principle thermostat, integral filter washers and check valves, virtual shutoff upon loss of cold water supply, and a locking mechanism for the temperature setting. The maximum pressure is 150 psi (10.3 bar). The adjustable field range temperature is 90 to 160 degrees F (32 to 71 degrees C).
Features- Lead free brass construction
- Thermal actuation technology for precise temperature control
- Integral filter washers and check valves
- ASSE 1017 certified, IAMPO cUPC certified, approved to CSA B125.3
