Horizontal Bucket Traps

The IB18S Series horizontal inverted bucket traps are ideal for general condensate removal service and feature a built-in strainer, heavy-duty cast iron body, and stainless steel bucket for long-term operation and reliability. For process, heating and dripleg services with pressures to 250 psig (17,2 bar). Available in 1/2" through 1-1/4".

Inverted bucket steam traps utilize the difference between the density of gas and liquid. The bucket is submerged, once the trap has been primed after installation. When steam enters the trap, it collects in the inverted bucket causing it to become buoyant, and rise close to the discharge valve. When condensate enters the trap, and the steam condenses within the bucket, the weight of the bucket multiplied by the linkage's leverage, exceeds the differential pressure hold in the valve to the seat and the bucket sinks. This opens the discharge valve to discharge accumulated air, CO2, other non-condensable gasses, and the condensate. As the condensate drains and steam enters the trap, the cycle repeats with the bucket filing with steam, rising again to close the discharge valve.

Features & Benefits
  • Easy in-line inspection and maintenance: simply remove the top for easy access to the trap internals for inspection or repair
  • Built-in strainer – for protection of trap and valve mechanism and the reduction of required piping and fittings
