State Supply offer radiator steam traps from several different manufacturers, such as Armstrong and Mepco. Radiator steam traps are found on radiators, convectors, and related equipment in steam heating systems. Usually operating under 15 psi of steam or less, radiator traps often make up the largest population of steam traps in your low-pressure steam heating system. The single operating component within the radiator trap is a thermostatic element which opens to let condensed steam out and closes to prevent steam from going beyond its point of use. Radiator traps are available in several different connection sizes and operating pressures.
