Armstrong 880 Series Inverted Bucket Trap In Stock

Armstrong inverted bucket steam traps only have two moving parts - the valve lever assembly and the bucket. That means no fixed points, no complicated linkages. Nothing to stick, bind or clog. Armstrong inverted bucket steam traps open and close based on the difference in density between condensate and steam-the inverted bucket principle. They open and close gently, minimizing wear. This simple fact means that inverted buckets are subject to less wear than some other types of traps. In fact, as an Armstrong inverted bucket trap wears, its tight seal actually improves. The ball valve and seat of the Armstrong steam trap provide essentially line contact resulting in a tight seal because the entire closing force is concentrated on one narrow seating ring. An Armstrong inverted bucket trap continues to operate efficiently with use. Gradual wear slightly increases the diameter of the ball valve. But the more it wears, the tighter the seal. The ball valve seats itself deeper as wear increases, preserving a tight seal.
