Ball float steam traps
Overview
Spirax Sarco FT ball float steam traps operate on the density difference between steam and condensate. They handle changing condensate loads efficiently and are largely unaffected by sudden pressure changes. For their size, these traps offer very high discharge capacities, up to 150,000 kg/h, and discharge condensate continuously as it is formed. That makes them especially well suited to steam process control equipment. The range is compact, works efficiently at both high and low condensate loads, includes integral air venting as standard and can be supplied with steam lock release devices where required. That continuous drainage behaviour makes ball float traps a common choice where condensate backup would directly affect heat transfer, temperature stability or process quality. They are therefore a strong fit for heat exchangers and process plant where stable condensate removal directly affects output quality.
Related continuous-drainage routes
Ball float designs are usually chosen where continuous drainage directly affects thermal output. If the installation is a heat-transfer duty, continue into steam heat exchangers. When condensate back-up is caused by stalled conditions rather than trap selection alone, compare pressure powered pumps.
If the duty instead favours compact high-pressure drainage or simpler disc construction, review thermodynamic steam traps.

Continue your continuous-drainage trap selection
Ball float steam traps are usually selected together with maintenance approach, connector strategy and wider condensate management priorities.
Compare the wider trap portfolio
Return to the wider steam traps range when you need to compare ball float traps with thermodynamic, inverted bucket or thermostatic trap families.
Standardise maintenance around the trap
Use swivel connectors and trapping stations when faster trap replacement and standardised maintenance matter as much as the trap type itself.
Add condition visibility to trap performance
Review wireless steam trap monitoring when the next priority is earlier fault detection and better visibility across the installed trap population.
