180 Series Free-Floating Lever Drain Traps


For pressures to 400 psig (28 bar) . . . Capacities to 2,000 lb/hr (907 kg/hr)

All-stainless steel for horizontal installation.

Armstrong’s stainless steel, free-floating guided lever drain traps use the same bodies, caps, lever mechanisms, valves and seats as Armstrong inverted bucket steam traps that have been proved in years of service. Elliptical floats and high leverage make it possible to open large orifices to provide adequate capacity for drain trap size and weight.

The hemispherical valve, seat and leverage of the 180-LD and 181-LD stainless steel traps are identical in design,
materials and workmanship to those for saturated steam service up to 570 psig (39 bar), except that the 180 Series traps have a guidepost to ensure a positive leak-tight valve closing under all conditions. The 180 Series is designed for situations where mounting a drainer close to the floor is critical. A back vent connection is required.
