Spirax Sarco FTS14 is an austenitic stainless steel (316) ball float steam trap with an integral automatic air vent. It is available in sizes 1/2" to 1" (DN15-DN25) with flanged, screwed, or socket weld connections. Designed for PN25 conditions.

Spirax Sarco FTS14 Ball Float Steam Trap

Product Overview

The FTS14 is an austenitic stainless steel (316) ball float steam trap with an integral automatic air vent. It provides efficient condensate drainage and prompt air removal to ensure process equipment operates to its maximum potential.

As standard, the FTS14 has horizontal connections with flow from right to left (R-L). However, its unique design allows the cover to be simply rotated to provide horizontal left to right (L-R) and vertical up or vertical down configurations.

Key Features

  • High Corrosion Resistance: All 316 austenitic stainless steel body and internals.
  • Versatile Orientation: Easily rotatable cover for horizontal (L-R, R-L) or vertical installation.
  • Integral Air Venting: Built-in automatic air vent ensures quick start-ups.
  • Hygienic Option: Tri-clamp ends available for sanitary applications (FTS14-4.5 only).

Sizes and Pipe Connections

Available sizes: ½", ¾", 1" and DN15, DN20, DN25.

Connections:

  • Screwed: BSP T Rp (ISO 7-1) or NPT
  • Socket weld: ASME B 16.11, BS 3799 Class 3000
  • Flanged: EN 1092-1 PN16/PN25, ASME B 16.5 Class 150/300
  • Tri-clamp: For hygienic/sanitary applications (FTS14-4.5 only)
