FTT Float & Thermostatic Ductile Iron Steam Traps

DRIP, PROCESS:  FTT Float & Thermostatic Ductile Iron Steam Traps with in-line pipe connections are used for the removal of condensate and air in HVAC and industrial process applications such as unit heaters, water heaters, pressing machines, heat exchangers and coils. They contain a high-quality welded stainless steel thermostatic air vent and stainless seat and mechanism. F&T traps have excellent air handling capability, making them a better choice than Inverted Bucket traps for most process applications. For drip applications, such as draining steam mains and steam supply lines, use 1/2” or 3/4” sizes.

  • Ductile Iron has a higher pressure and temperature rating and is more resistant to shock loads than cast Iron
  • All stainless steel internals with hardened seat and wear parts
  • In-line repairability is simplified by having all internals attached to the cover
  • Welded stainless steel thermostatic air vent resists shock from waterhammer. Live orifice air vent is available for superheated applications
  • Excellent air handling capability allows air to be discharged rapidly so steam can enter the system quickly during start-up
  • F&T traps discharge condensate immediately as it is formed (no condensate will back up into the system)

Description

FTT Float & Thermostatic Ductile Iron Steam Traps have Ductile Iron Bodies ••• In-Line Pipe Connections ••• 300 psig Operating Pressures ••• All stainless Steel Internals. Typically used on steam process applications such as unit heaters, pressing machines, heat exchangers, steam coils. Contain a welded stainless steel thermostatic air vent for rapid air removal on system start-up, important on process applications.

Float and thermostatic traps contain a float and seat mechanism with a separate thermostatic element which work together to remove both condensate and air from the steam system. The float, which is attached to a valve, rises and opens the valve when condensate enters the trap. This allows the condensate to discharge. Air is discharged through the thermostatic air vent to the outlet side of the trap. Steam entering the trap causes the thermostatic element to expand, closing the air vent and trapping the steam.
