How Inverted Bucket Traps Work
The inverted bucket mechanism uses steam buoyancy to keep the bucket floating and the valve closed, retaining live steam in the system. When condensate enters, the bucket loses buoyancy and sinks, opening the valve to discharge condensate and non-condensable gases. This simple, mechanically robust design offers excellent resistance to water hammer and operates reliably across a wide range of load conditions.
Typical Applications
- Steam distribution mains and branch lines
- Unit heaters and heat exchangers
- Drip legs and steam tracer lines
- Industrial process heating systems
