Stainless Steel Free-Floating Guided Lever Drain Traps


For loads to 9,500 lb/hr (4309 kg/hr) . . . Pressures to 570 psig (39 bar)

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 11-LD, 22-LD and 13-LD stainless steel traps are identical in design, materials and workmanship to those for saturated steam service up to 570 psig (39 bar), with the exception of the addition of a guidepost to assure a positive, leak-tight valve closing under all conditions.
