Spirax-Sarco FT-125 Float & Thermostatic Steam Trap
The Spirax-Sarco FT-125 (SKU 58453) is a 1-1/4″ Float & Thermostatic (F&T) steam trap engineered for dependable, continuous condensate discharge in commercial and industrial steam systems. Rated at 125 PSI, this trap combines a float-operated main valve with a thermostatic air vent to deliver efficient, uninterrupted drainage while preventing live steam loss.
How It Works
The float mechanism responds instantly to condensate levels, opening the main valve to discharge condensate as it accumulates. The integrated thermostatic element vents air and non-condensable gases at startup and during operation, ensuring rapid system warm-up and sustained efficiency throughout the steam system.
