Xylem-Hoffman Specialty Series H Float & Thermostatic Steam Trap — Model FT015H-8
The Xylem-Hoffman Specialty 401629 is a heavy-duty Series H Cast Iron Float & Thermostatic (F&T) Steam Trap engineered for dependable condensate drainage and air venting in low-pressure steam heating systems. With a 2″ NPT connection and a 15 PSI operating pressure rating, this trap is built to handle the demands of commercial and industrial steam distribution with long-lasting reliability.
Key Features
- Series H cast iron body construction for rugged, long-service performance
- 2″ NPT inlet and outlet connections for easy in-line installation
- 15 PSI maximum operating pressure rating
- .687″ orifice for optimized condensate flow capacity
- Integrated thermostatic air vent for automatic non-condensable gas discharge
- Float & Thermostatic design provides continuous condensate removal without steam loss
- Model FT015H-8 — direct replacement for compatible Hoffman Specialty applications
How Float & Thermostatic Traps Work
F&T steam traps use a float mechanism to continuously discharge condensate as it accumulates, while a separate thermostatic element vents air and non-condensable gases at startup and during operation. This dual-action design prevents waterlogging, reduces energy waste, and protects steam system equipment from corrosion and water hammer.
Typical Applications
- Low-pressure steam heating mains and branch lines
- Unit heaters and heat exchangers
- Steam coils and radiator systems
- Commercial and light industrial steam distribution
