Description

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
