Armstrong D1547-213 Steam Trap is a cast-iron inverted-bucket trap (Model 213) with a 3/4" NPT connection, designed for inline vertical installation in steam systems. It is rated for service up to 250 psig and uses a 3/16" discharge orifice, featuring a free-floating stainless steel mechanism that provides reliable condensate discharge through a top-mounted orifice while venting non-condensable air. As part of Armstrong’s 213-series inverted bucket traps, this unit delivers rugged performance in industrial piping where dependable condensate removal at moderate to high pressures is required, all in a compact, 3/4" threaded form factor compatible with standard piping.
