Description

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.

Operation

Key to the reliability of a Barnes & Jones Bucket Trap is that 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 being used for a greater differential than its rating will not open. Conversely, a trap with a rating that 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 through the inlet tube. Air is vented from a small orifice at 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 buoyant, 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.
