Flowex Ball Float Steam Trap

The Flowex Ball Float Steam Trap is a key component in steam systems, designed to continuously discharge condensate while retaining dry steam, improving heat transfer efficiency and reducing energy losses.

Using a float-operated discharge valve, the trap responds instantly to condensate level changes, ensuring stable operation even under fluctuating loads. This makes it suitable for a wide range of industrial applications.

Industrial Applications

✔ Industrial boilers and steam distribution lines
✔ Heating equipment, storage tanks, drying systems
✔ Textile, paper, chemical, and food processing plants
✔ Systems that require continuous high-capacity condensate discharge

Key Advantages

  • Continuous condensate removal – prevents water hammer & efficiency loss
  • Wide size range: DN15 to DN200
  • Multiple pressure classes: 4.5 bar, 10 bar, 14 bar, 32 bar, 45 bar, 65 bar
  • Long lifespan – available in cast iron, carbon steel or stainless steel
  • Built-in air vent – removes non-condensable gases for better heat transfer
  • Stable performance under varying load conditions
