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
