Hoffman Specialty 404220 Trap

The Hoffman Specialty 404220 (Model FT015H-5) is a heavy-duty, 1-1/4" NPT float and thermostatic steam trap engineered for modulating steam pressures. This Series H "Bear Trap" is a direct replacement for 0036098 and IFT-15-1 1/4, specifically designed to handle the widely varying loads typical in steam heating and process equipment. With a maximum operating pressure of 15 PSI and a substantial 0.312" orifice, this trap provides continuous condensate drainage while the rugged thermostatic air vent handles rapid air removal during start-ups. The cast iron body construction and stainless steel internal components ensure resilience against water hammer and corrosive conditions. Its universal 4-port design—featuring two inlets and two outlets—provides significant piping flexibility for contractors, allowing for both same-side and opposite-side configurations. This model is optimized for sub-atmospheric steam systems and applications where venting air and non-condensable gases at low pressures is critical for thermal efficiency.

Key Benefits

• Universal 4-Port Tapping: Dual inlet/outlet configuration allows for flexible installation and simplified maintenance in tight mechanical rooms.
• High Condensate Capacity: Efficiently handles up to 2,340 lbs/hr at a 15 PSI differential, preventing backup in the heat exchanger.
• Stainless Steel Internals: Hardened stainless steel valve pin, seat, and float provide superior resistance to erosion and chemical attack.
• Air Binding Prevention: The integrated thermostatic air vent stays open during start-up to purge air and closes tight when steam temperature is reached.
• In-Line Serviceability: The removable cover allows for internal inspections and parts replacement without disturbing the main piping.

Common Questions

Is the FT015H-5 compatible with vacuum systems?
Yes, the Series H traps are specifically designed for systems with modulating steam pressure from maximum down to vacuum, making them ideal for temperature-regulating valve applications.

What is the benefit of the .312" orifice?
The .312" orifice is precision-sized for 15 PSI differential service, allowing for high-volume condensate flow while maintaining a tight seal against steam loss once the float drops.

Can I install a test valve directly on this trap?
Yes, the additional outlet port in the 4-port design provides a convenient location for installing a test valve or vacuum breaker without extra manifolding.
