Spirax-Sarco FTI-125 is a cast-iron float and thermostatic steam trap with a 3/4 in NPT connection and an inline flow pattern, designed to continuously discharge condensate from steam lines while venting non-condensable gases. It has a maximum operating pressure of 125 psi. Inside, a float valve modulates to discharge condensate at steam temperature, while an internal balanced-pressure thermostatic air vent releases non-condensables to keep steam distribution efficient. Common applications include condensate removal from steam coils, heat exchangers, and other steam-using equipment in industrial plants.
