TLV Free Float Steam Traps for Main Lines

  • Free Float® steam traps for main lines that provide a tight seal even under low condensate load conditions. 
  • A typical characteristic of steam distribution mains is that the amount of condensate generated in them is usually quite small. Steam traps used for main drainage have long hours of operation and are often installed outdoors. These traps should therefore have the lowest possible functional steam loss to minimize operating cost over the long term and provide long, reliable service.
  • The TLV SS / SH / FS series have been designed with precisely these points in mind, offering a range of features that make them ideal for use on steam distribution mains.
  • Energy Conservation
    • The valve opening is under a continuous water-seal, so no steam can escape through the valve. In the case of small condensate loads, such as in superheated steam lines, the Free Float’s 3-point seating holds the float tightly against the valve opening to ensure that no steam is allowed to escape.
  • Prevention of Start-up Trouble
    • The automatic air vent design opens the air vent valve at start-up to discharge any low temperature air inside the system. This prevents air-binding, which can be caused by initial air.
  • Long Service Life
    • The spherical Free Float® rotates during operation, allowing any point on its surface to act as the valve seal and thus ensuring long service life.
