Xylem 401893 Float and Thermostatic Steam Trap 2 Inch 125 PSI

The Xylem 401893 FT125C-8 is a professional-grade float and thermostatic (F&T) steam trap designed for continuous drainage in commercial and industrial steam systems. This Series C trap features a 2-inch NPT connection in a same-side configuration, with an inlet on the top end of the cover and a condensate discharge outlet on the bottom end of the cover.

Key Features:

• Cast iron construction with 125 PSI maximum operating pressure
• Maximum temperature rating of 377°F
• Capacity of 8,150 pounds per hour
• Stainless steel internal parts for durability
• Thermostatic vent in the top allows free passage of air during start-up and closes near saturation temperature
• Operates on the density principle

Operation: As condensate fills the float chamber, the float rises and through a lever mechanism pulls a valve off its seat, opening the orifice of the discharge valve. The opening and closing of the seat provides modulation to handle light or heavy condensate loads. The water forms a seal that prevents live steam loss.

These traps are designed for service on heat exchange equipment where there is a need to vent air and non-condensable gases quickly. They are recommended for modulating pressures where widely varying loads are present and are a good choice for their ability to vent air at very low pressures, handle start up air loads, and operate against back pressure.
