Description
Spirax-Sarco FT-125 Float & Thermostatic Steam Trap — 3/4″ | 125 PSI
The Spirax-Sarco FT-125 is a high-quality float and thermostatic (F&T) steam trap engineered for reliable, continuous condensate drainage in steam heating and process systems. Rated for 125 PSI working pressure, this 3/4″ trap is ideal for a wide range of commercial and industrial hydronic and steam applications where dependable condensate removal is critical to system efficiency and equipment protection.
How It Works
The FT-125 combines two proven mechanisms in a single compact body. The float mechanism responds immediately to condensate accumulation, opening the valve to discharge condensate continuously without allowing live steam to pass. The thermostatic air vent automatically purges non-condensable gases (air) from the system at startup and during operation, improving heat transfer and preventing air binding.
