The Heat-Gard Series “54” valve is designed to save energy by controlling hot water or low pressure steam heat in freestanding radiators, convectors, baseboards, fan coil units and the like in a loop, a zone or a unit. The valve, coupled with a Heat-Gard Series “54” operator, provides a reliable automatic modulating unit. As room temperature drops, the Heat-Gard Series “54” valve opens to allow more hot water or steam to flow through the radiator, thus allowing more heat into the room. When the room approaches the selected temperature, the operator causes the valve to begin closing off the flow of hot water or steam. This continued monitoring of the temperature is fully automatic, using no electricity whatsoever. The Heat-Gard Series “54” valve can be equipped with any wide variety of Heat-Gard Series “54” operators.
