Description
Xylem-Hoffman Specialty Series B0 Inverted Bucket Steam Trap — Model B0125A-3
The Xylem-Hoffman Specialty 404190 is a Series B0 Cast Iron Inverted Bucket Steam Trap engineered for reliable, energy-efficient condensate removal in steam heating and process systems. Featuring a 3/4″ NPT connection and rated to 125 PSI, this trap is built to handle demanding commercial and industrial steam applications with proven durability.
How Inverted Bucket Traps Work
The inverted bucket mechanism operates on the principle of buoyancy. When steam enters the trap, the inverted bucket floats and closes the discharge valve, retaining steam in the system. As condensate accumulates and displaces the steam, the bucket sinks and opens the valve, discharging condensate efficiently. This design provides continuous, automatic operation with minimal steam loss and long service life.
