980 Series Inverted Bucket Steam Traps

Description

Cast steel for horizontal installation with integral strainer

For pressures to 600 psig (41 bar) . . .
Capacities to 4,400 lb/hr (2000 kg/hr)

Armstrong offers two sizes of cast steel
inverted bucket traps with in-line horizontal pipe connections and
integral strainers with a choice of screwed, socketweld or flanged
connections.

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.

Inverted bucket traps drain continuously,
although discharging intermittently, allowing no condensate backup. They
are also resistant to water hammer.
