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.
