TF1 Slip-On Tideflex Duckbill Check Valve with curved bill

The TF-1 has become the preferred Tideflex configuration for outfalls. Designed for in-structure and end-of-pipe installations, the TF-1 features a flat bottom and flared top. This allows the valve to be installed at a lower overall elevation than other configurations, with less bottom clearance required. This is especially important in low-lying areas where maintaining as much driving head is critical, or where silt, sand and debris might tend to collect beneath the valve.

  • Ideal for manhole installations
  • Minimal bottom clearance required
  • Lightweight, all-elastomer design
  • Seals around small solids
  • Available in slip-on or flanged design
