Sterling Float & Thermostatic Steam Traps

Float & Thermostatic (F&T) steam traps are preferred for efficient, economical vacuum and pressure service. F&T traps are highly recommended for applications where large volumes of air are present on start-up and where condensing rates can vary widely. F&T traps are ideal for service in health care institutions, apartments, educational facilities, offices and other public areas as well as in business and industry.

Dependable, Trouble-free, Float Actuation

F&T traps operate in response to rising and falling condensate levels and rising and falling temperatures near thermostatic vent, as follows:

  • Condensate initially fills the trap body to a predetermined level, which is sufficient to seal the valve seat opening.

  • As the condensate level continues to rise, the float will rise causing the valve to pull away from the seat

  • Condensate will then be discharged into the return line through the trap outlet. The rise and fall of condensate level causes a continuous discharge which is typical of F&T traps.

  • Air entering the trap is discharged through the thermostatic vent. The opening and closing of the vent is dependent upon the temperature surrounding the thermostatic element.

  • As the element cools with more air accumulating, it opens to allow the air to vent to atmosphere.
