  • Parallel Series

  • H-Pattern Float & Thermostatic Steam TrapFeatures:

    • H-Pattern 
    • Available in 1/2” -2” sizes
    • Efficient, Continuous, Immediate Discharge.
    • High Air Handling capacity reduces Warm Up.
    • Repairable on line
    • Water sealed valve for zero blow by
    • Condensate discharges at saturated steam temperatures

    Operation:

    When the system starts up, the steam pushes air and noncondensable gas out through the thermostatic air vent. As steam enters the trap, the thermostatic air vent responds by snapping shut and stopping the passage of live steam. As the steam gives up its energy and condenses back to water, the water level rises, lifting the float which opens the valve and discharges the condensate into the return line through the trap outlet. When the water level drops, the weight of the float closes the valve maintaining the water seal.

    Applications:

    • Steam Main Drips
    • Unit or Space Heaters
    • Process Equipment
    • Water Heaters
    • Chillers and Coils

    Description:

    The In-line Float & Thermostatic traps Series FTI are designed for all types of low pressure (up to 125 psi) or vacuum steam heating systems and steam process equipment. Typical applications include; unit heaters, space heaters, water heaters, pressing machines, low pressure mains and risers, and replacement of inefficient inverted bucket traps. In-Line Float & Thermostatic traps are especially well suited for apartments, hospitals, office buildings, and schools or wherever quiet operation is necessary.

    Operation:

    The opening and closing of the valve is caused by changes in the condensate level within the trap shell. When the water level drops, the weight of the float closes the valve. As condensate enters the traps, the float rises and opens the valve, allowing the condensate to be discharged. The float is designed to provide sufficient buoyancy to overcome the differential pressure across the valve. The internal float and valve configuration is such that the condensate level is always above the valve, creating a continuous water seal at the seat. Air and other gases are freely discharged as they reach the trap through the air vent. The calibrated thermostatic element will close the air vent immediately when the temperature surrounding the element reaches saturated steam temperature.

    Construction:

    In-line Float and Thermostatic traps are compact, of rugged design, with easy access to all interior parts. The body is cast with In-line pipe connections for simple straight through pipe hook-ups. The air vent valve, seat, and the complete valve mechanism are manufactured from stainless steel. The repair kit consists of a complete, factory assembled head which simply bolts on to the body for ease of repair. No pipe connections need to be broken.
