Description
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. All Armstrong cast iron inverted bucket steam traps
are repairable for even bigger maintenance savings.
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, preventing 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.
Inverted bucket traps drain continuously, although discharging intermittently,
allowing no condensate backup. They are also resistant to water hammer.
