Inverted Bucket Steam Trap Manufacturer in USA
An inverted bucket steam trap is a mechanical condensate discharge device designed for long-term operation in industrial steam systems where durability and resistance to harsh operating conditions are critical. Its operating principle relies on density difference between steam and condensate, allowing the trap to automatically discharge condensate while preventing live steam loss. Inverted bucket steam traps are widely selected for steam mains, drip legs, and process equipment where reliability outweighs rapid response.
SVR Global is a reputed Inverted Bucket Steam Trap Manufacturer and Supplier in USA, supplying engineered steam trap solutions for power generation, refining, chemical processing, and industrial utility systems. Our inverted bucket steam traps are designed for stable operation, resistance to water hammer, and consistent condensate removal under fluctuating steam loads.
With hands-on experience supporting EPC contractors, maintenance teams, and plant operators across the United States, SVR Global delivers steam traps that comply with project specifications and long-term operational requirements.
What Is an Inverted Bucket Steam Trap?
An inverted bucket steam trap operates using a sealed inverted bucket connected to a discharge valve inside the trap body. When condensate enters the trap, the bucket loses buoyancy and sinks, opening the discharge valve to release condensate. When steam enters, it fills the bucket, increasing buoyancy and lifting it to close the valve, preventing steam loss. As steam inside the bucket condenses, buoyancy decreases and the cycle repeats.
This cyclic operation makes inverted bucket steam traps mechanically simple, rugged, and suitable for continuous industrial service.
Inverted Bucket Steam Trap Applications in Industrial Steam Systems
SVR Global inverted bucket steam traps are used in a wide range of steam applications, including:
- Condensate drainage from steam mains and distribution headers
- Drip leg installations to prevent water accumulation
- Steam-heated heat exchangers and jacketed vessels
- Process equipment operating under steady steam pressure
- Industrial utility steam systems exposed to vibration and water hammer
These applications demand steam traps with consistent operation, strong internal components, and tolerance to contaminated condensate.
Types of Inverted Bucket Steam Traps
SVR Global manufactures and supplies inverted bucket steam traps in multiple configurations to suit different installation and service conditions:
