Xylem 404242 Float Thermostatic Steam Trap - FT015X-8 2

The Xylem 404242 is a high-capacity Series X float and thermostatic steam trap designed for efficient condensate removal and air venting in commercial and industrial steam heating systems. This heavy-duty trap features a 2-inch NPT threaded connection in a same-side configuration for straightforward in-line horizontal installation.

Key Features:

• Cast iron construction for exceptional durability and long service life
• 15 PSI maximum operating pressure with capacity up to 24,000 pounds per hour
• Maximum operating temperature of 377°F (can handle pressures up to 175 PSI)
• Stainless steel internal components including valve trim, float, and air vent for corrosion resistance
• Float-operated mechanism provides continuous, automatic condensate drainage
• Integrated thermostatic element allows rapid air and non-condensable gas venting during system start-up
• Removable cover design enables easy in-line maintenance without removing the trap from the line
• Large port design handles high condensate capacity loads

Applications:

• Steam main drip traps and heating systems
• Shell and tube heat exchangers
• Unit heaters and air handling coils requiring fast venting
• Tank heaters with modulating temperature control
• Steam humidifiers and separators
• Process equipment with varying condensate loads

The float and thermostatic design operates on the density principle, with a thermostatic vent that opens during start-up to release air, then closes near saturation temperature. As condensate enters the float chamber, the rising float opens the discharge valve through a lever mechanism, providing modulation to handle light or heavy loads while preventing live steam loss. This trap is part of the Hoffman Specialty line, a trusted brand in steam system components since 1913, now manufactured by Xylem.
