How Inverted Bucket Traps Work
The inverted bucket steam trap operates on the principle of buoyancy. When steam enters the trap body, the inverted bucket floats upward, closing the discharge valve. As condensate accumulates and the bucket loses buoyancy, the valve opens and condensate is discharged. This continuous cycle ensures efficient condensate removal while preventing steam loss — maximizing system efficiency and protecting downstream equipment.
Typical Applications
- Commercial and industrial steam distribution systems
- Steam mains and branch line drip stations
- Heat exchangers and process heating equipment
- Unit heaters and steam coils
