Armstrong Forged Steel Free Floating Lever Drain Traps use the same bodies, caps, lever mechanisms, valves and seats of Armstrong inverted bucket steam traps that have been proven 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 32-LD, 33-LD and 36-LD forged steel traps are identical in design, materials and workmanship to those for saturated steam service up to 1,000 psig (69 bar) with the exception of the addition of a guidepost to assure a positive, leaktight valve closing under all conditions.
This products are also available with cast T-316 stainless steel body & all stainless steel internal
For high pressure application 17-4 PH SS is reccomended for valve & seat material
