Description

The Sterlco FT90-3-75IL In-Line Float & Thermostatic Trap .75″ NPT 75PSI is designed for all types of low pressure or vacuum steam heating systems and steam process equipment. The Sterlco FT90-3-75IL 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 trap, 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.

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 and thermostatic traps are especially well suited for apartments, hospitals, office buildings and schools or wherever quiet operation is necessary.

FT90 Specifications Sheet pdf

Note on capacity: Trap capacities are based on continuous discharge at steam temperatures. The published figures are the result of an extensive testing program conducted in accordance with ANSI/ASME PTC 39.1-1980, Condensate Removal Devices for Steam Systems. Significantly greater applications are realized when condensate temperature is below saturated steam temperature. A safety factor between 2-4 should be applied to these ratings.
