Same inverted bucket principle. Different package. Now the
energy-saving performance and reliability of the inverted bucket steam
trap are available in a versatile new package.
The most reliable steam trap known—the inverted bucket—provides
efficient condensate drainage of virtually all types of steam-using
equipment. Put the inverted bucket to work in a tough cast iron package,
and you have the best of both worlds. Because they operate efficiently
for longer periods of time, Armstrong cast iron inverted buckets add
solid energy savings to lower replacement/labor costs. Armstrong cast
iron inverted bucket traps are repairable, for even bigger maintenance
A unique leverage system multiplies the force provided by the bucket
to open the valve against system pressure. The mechanism is
free-floating and has no fixed pivots to create wear or friction.
Because the mechanism is located at the top of the trap, no dirt can
collect on the orifice. Small particles of dirt are held in suspension
until discharged by the full differential purging action when the bucket
sinks, pulling the valve off the seat.
The discharge orifice is surrounded by a water seal, which prevents
live steam loss. Automatic air venting is provided by a small vent hole
in the bucket, which provides continuous automatic air and CO2 venting at steam temperature.
You’ll still enjoy all these familiar benefits with the Armstrong
trap valve station. But what you’ll find new are all the benefits of a
piston valve integrated in the same space-saving package.
