5000 Series Inverted Bucket Steam Traps in forged chrome-moly steel traps for vertical installation with a choice of screwed, socket weld 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. This provides continuous automatic air and CO2 venting at steam pressure.
Inverted buckets drain continuously, although discharging intermittently, to prevent condensate backup. They are also resistant to water hammer.
