Float & Thermostatic Steam Traps

Float & Thermostatic 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. F & T traps operate in response to rising and falling condensate levels and rising and falling temperatures near thermostatic vent. Dimensional Information

• Choose from 21 standard capacity models
• Models available in five connection sizes from
  1/2 in. to 2 in..
• Designed for ease of installation and simplified, minimal maintenance.
• Time tested design and quality materials for longer service life.
• Designed specifically for maximum condensate removal at six different pressure ratings.

Install F&T traps in steam applications such as Instantaneous Heaters, Steam Humidifiers, Steam-Jacketed Vessels, Unit Heaters, Sterilizers and other similar equipment. Pictured at right are diagrams of typical installations.

F&T traps operate in response to rising and falling condensate levels and rising and falling temperatures near the 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 the atmosphere.
