Steam Trap
Pressures To 250 PSIG
Temperatures to 450°F
Withstands Severe Conditions
Heavy wall cast iron cover and
body provide many years of
trouble free service.
Smooth Action and
Tight Shutoff
Stainless steel linkage, valve
and seats are precision
manufactured to insure
optimal performance.
Ideal for
“Dirty” Systems
Valve and seat located at
top of trap and stainless
steel strainers available on
most horizontal models
ensure long service.
Maximum Compatibility
with Existing Installations
Pressure change assemblies
are interchangeable with
Armstrong which guarantees
maximum flexibility when
stocking repair parts.
Easy to Maintain
Working parts lift out with
top for quick inspection
and maintenance.
Resists Corrosion
Stainless steel bucket
provides maximum
service life with
minimum deterioration.
Minimizes Effects of
Water Hammer
Open bucket design avoids
collapse typical of sealed floats.
Suitable for Wide Variety
of Loads/Applications
Horizontal and vertical models in
thirteen body sizes are one of the
most comprehensive inverted
bucket trap lines available.

Pressures To 250 PSIG (17.2 barg)

Trap Closed – After trap is installed
and primed, steam entering the
trap collects in the top of the
bucket, floating the bucket and
forcing the valve into its seat.
Trap Begins to Open – As
condensate begins to flow into the
trap, steam and air are forced from
the bucket. This causes the bucket
to begin losing buoyancy, tending
to pull the valve from its seat.
Trap Discharges – When enough
condensate has entered the trap,
displacing the steam and air, the
bucket drops, pulling the valve
from the seat and allowing
condensate and air to discharge.
Trap Closes – As the flow of
condensate stops, steam enters
the trap and refloats the bucket,
forcing the valve into its seat. The
cycle then repeats as more
condensate reaches the trap.
OPERA TION
Hardened Stainless Steel Valve and Seat — Long life and
maximum corrosion resistance.
Stainless Steel Bucket — Long lasting, rugged and
naturally resistant to water hammer.
Inexpensive — Low maintenance and initial cost.
Repairable in-line — All working parts lift out of top of trap.
Cast Iron Body — Durable heavy wall construction
provides years of reliable service.
Suitable for Wide Variety of Loads/Applications — Hori-
zontal and vertical models in thirteen body sizes.
Resists Dirt and Scale — Valve and seats positioned at
top of traps and internal stainless strainer available on
most horizontal models ensure long service.

After trap is installed and primed, steam entering the
trap collects in the top of the bucket, floating the
bucket and forcing the valve into its seat. As
condensate begins to flow into the trap, steam and
air are forced from the bucket. This causes the
bucket to begin losing buoyancy, tending to pull the
valve from its seat. When enough condensate has
OPERA TION
entered the trap, displacing the steam and air, the bucket
drops, pulling the valve from the seat and allowing
condensate and air to discharge. As the flow of
condensate stops, steam enters the trap and re-floats the
bucket, forcing the valve into its seat. The cycle then
repeats as more condensate reaches the trap.
