Armstrong International 11/22/13-LD Series Free Floating Lever Drain Trap

Armstrong International 11/22/13-LD Series free floating lever drain trap uses the same bodies, caps, lever mechanisms, valves, and seats as the 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 barg), with the exception of the addition of a guidepost to assure a positive, leak-tight valve closing under all conditions.
