Description
Xylem-Hoffman Specialty Series H Float & Thermostatic Steam Trap — Model FT015H-4
The Xylem-Hoffman Specialty 404210 is a heavy-duty Series H Float & Thermostatic (F&T) Steam Trap engineered for reliable condensate removal and automatic air venting in low-pressure steam heating systems. Built with a rugged cast iron body, this trap handles the demands of commercial and industrial hydronic steam applications where dependable performance and long service life are essential.
Key Features
- 1″ NPT connections for straightforward installation in standard steam piping
- 15 PSI maximum operating pressure rating
- Series H cast iron body construction for durability in demanding steam environments
- .253″ orifice for precise condensate discharge control
- Integrated thermostatic air vent automatically purges non-condensable gases and air from the system
- Float-operated mechanism provides continuous, modulating condensate discharge
- Dual-function design combines float trap and thermostatic air vent in a single compact unit
How Float & Thermostatic Traps Work
Float & Thermostatic steam traps use a buoyant float to continuously discharge condensate as it accumulates, while the integrated thermostatic air vent opens to release air and non-condensable gases at startup and during operation. This combination ensures rapid system warm-up, prevents air binding, and maximizes heat transfer efficiency throughout the steam distribution system.
Typical Applications
- Low-pressure steam heating systems in commercial and institutional buildings
- Unit heaters, convectors, and radiators
- Steam coils and heat exchangers
- Drip legs and steam mains
- Process heating equipment operating at or below 15 PSI
