Armstrong D1547 Steam Trap

Armstrong D1547 Steam Trap is a 3/4-inch NPT cast-iron inverted bucket steam trap (213CV variant) designed for reliable condensate drainage in steam systems. The 213CV suffix denotes an internal check valve, a feature recognized in Armstrong's CV-equipped inverted bucket traps. With a maximum operating pressure of 250 psig and a maximum temperature of 450°F, it suits standard boiler-room applications and steam-using equipment. Built with a cast-iron body and threaded iron connections, this trap is part of Armstrong's rugged inverted bucket family, known for durability in mid-sized steam services. Armstrong data for 200 Series inverted bucket traps lists capacities around 20,000 lb/hr at typical operating pressures, illustrating its suitability for mid-sized condensate loads such as heat exchangers, steam coils, and process equipment. Applications include boilers, heat exchangers, steam distribution lines, and other process equipment requiring reliable condensate removal.
