Armstrong bucket steam traps including the 800, 880 and 200 series of bucket traps and their repair parts. All these Armstrong bucket steam traps come standard with stainless steel buckets. Armstrong steam traps are hearty and robust and can last for years. However, the valve mechanism and seat inside the steam trap should be replaced every 5 years to ensure there is no steam leakage from the steam trap. Choose from a variety of Armstrong steam trap models, pipe sizes and steam operating pressure ranges. On-the-shelf ready for same-day shipping! NOTE: Make certain to order the correct steam operating pressure for your application. The rated operating pressure (stamped on the trap's nameplate) of the Armstrong steam trap should always be the same or more than the actual steam pressure at the steam trap.
The inverted bucket steam trap is a simple design with a unique leverage system that multiplies the force provided by the bucket to open the valve against pressure. Because the bucket is open at the bottom, the trap resists damage from water hammer. With reinforced wear points and only two moving parts (the valve lever assembly and the bucket) Armstrong Inverted bucket traps are built to last. These Steam Traps have no fixed points, no complicated linkage and nothing to stick, bind or clog.
Virtually no steam loss ~ Steam does not reach the water-sealed discharge valve.
Purging action ~ Snap opening of the valve creates a momentary pressure drop and turbulence in the unit drained. This breaks up films of condensate and air and speeds their flow to the trap.
Dependable operation ~ Simple, direct operation with nothing to stick, bind or clog. Only two moving parts - the valve lever and the bucket.
Freedom from dirt problems ~ Condensate flow under the bottom edge of the bucket keeps sediment and sludge in suspension until it is discharged with the condensate. Valve orifice opens wide and closes tightly. No buildup of dirt or close clearances to be affected by scale.
Resistance to damage from water hammer ~ Open bucket or float will not collapse as a result of water hammer.
Excellent operation against back pressure ~ Since trap operation is governed by the difference in density of steam and water, back pressure in the return line has no effect on the ability of the trap to open for condensate and close against steam.
Continuous air and CO2 venting ~ Vent in top of bucket provides continuous automatic air and CO2 venting with no cooling lag or threat of air binding. Steam passing through vent is less than that required to compensate for radiation losses from the trap so it's not wasted.
Wear and corrosion resistance ~ Free-floating guided lever valve mechanism is "frictionless," and all wear points are heavily reinforced. All working parts are stainless steel. Valve and seat are stainless steel, individually ground and lapped together in matched sets.
