Armstrong International 811-3/4-15 3/4" Inverted Bucket Trap 15 PSI

The Armstrong International 811-3/4-15 3/4" inverted bucket steam trap works at a pressure of 15 PSI. This mechanical part operates on the buoyancy concept in which the inverted bucket is placed in condensate and opens and closes a valve due to the difference in density of steam and water. When steam enters the case, it forces the condensate and lifts the bucket to close the valve tightly. This trap is used extensively with heating coils and heat exchangers for condensate control and thermal energy recovery in HVAC systems. Among the advantages are reliability of operation, protection against water hammering, and low maintenance.
