This 1 in 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 cast copper silicon alloy, solder union connections, 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. The adjustable field range temperature is 60 to 120 deg F.
