The TF-1 is the most popular Tideflex Check Valve configuration for outfalls. The TF-1 has a flat bottom and a flared top designed for in-structure and end-of-pipe installations. As a result, the valve can be installed at a lower overall elevation than in other configurations, requiring less bottom clearance.
The TF-1 is ideal for maintenance hole applications such as junction boxes, diversion chambers, and interceptors where the pipe invert is close to the vault floor. The invert pipe is as close to the floor as possible in these vaults to maximize the available gravity head. The TF-1 is designed to install within such structures and can be easily retrofitted to existing systems, frequently replacing failed flapgates.
