This 3/4" hot water extender mixing valve is designed for domestic water supply systems and recommended for lower tempered radiant heat applications installed at or near the boiler or hot water heater. It consists of a lead free brass body, threaded connections, thermostat, stainless steel springs, and dial adjustment cap. The hydraulically operated thermostat opens a spring loaded check in the cold water inlet which allows cold and hot water to mix and can be replaced as a unit. The low temperature range is 100 to 130 degrees F (38 to 54 degrees C).
