WATTS® Temperature Control Valve, Series: LF1170, 1/2 in Nominal, Union Solder, 150 psi, 200 deg F, 0.5 gpm, Media: Water, Copper Silicon Alloy Body, Stainless Steel Trim, EPDM O-Ring, 4-13/16 in W x 5-3/8 in H

This lead free hot water control valve, 1/2 in, 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 cast copper silicon alloy, solder union connections, integral filter washers and check valves, solid wax hydraulic principle thermostat, virtual shutoff upon loss of cold water supply and a locking mechanism for the temperature setting. The maximum pressure is 150 psi. The adjustable field range temperature is 90 to 160 deg F.
