Series 2000 and Series 8000 Inverted bucket Traps


Designed for extended service and low maintenance with medium and high pressure steam, Barnes & Jones Bucket Traps feature an inverted bucket design with corrosion resistant stainless parts for optimal performance with blast coils, laundry equipment, hot water heaters, steam kettles and a broad range of industrial and process applications.


Key to the reliability of a Barnes & Jones Bucket Trap is that the the trap is selected for the actual pressure differential of your application, and the valve seat and plug are in the top, away from the dirt and debris that collects in the trap body. A trap be ing used for a greater dif ferential than its rating will not open. Conversely, a trap with a rating which exceeds the differential will operate at a reduced capacity.

Barnes & Jones offers seven models in 20 capacities. Using the table on the back of the downloadable specifications pdf, you can specify the B&J trap which delivers the most efficient energy saving operation and lowest maintenance cost.

Initially primed to create a water seal with the bucket in a down (fully open) position, air and water enter the trap though the in let tube. Air is vented from a small orifice in the top of the bucket, while condensate flows out from under the bucket. When steam enters the trap, it fills the bucket, causing it to become bouyant, overcoming the weight of the bucket, and rising to “snap” the plug into the seat. The trap stays fully shut until sufficient steam has co denses to allow the bucket to immediately drop, and return to its fully open state.
