Red Valve Series TF-2 Check Valve

 

The TF-2 was the first duckbill check valve introduced by Tideflex Technologies. The TF-2 was developed based on a United States Environmental Protection Agency (EPA) grant in the 1980s to overcome excessive costs in maintenance and replacement of non-performing flapgates. The TF-2 design has been enhanced by the TF-1 Flat-bottom Duckbill Check Valve. The TF-1 requires minimal bottom clearance and the inherent geometry and construction of the TF-1 yields a stronger, more durable check valve.

The TF-2 installs by slipping over the end of an exposed piece of pipe, and is fastened with compression clamps. The inside diameter of the TF-2’s cuff is fabricated to exactly match the outside diameter of the pipe.

The original Tideflex Check Valve design, the TF-2, has a flare on the top and bottom of the valve. It has been superseded by the TF-1 as Tideflex’s standard design, but remains available for customers who desire it for aesthetic reasons or space limitations.

The TF-2 can also be installed on the O.D. of elliptical pipe and many arch pipes. Tideflex Technologies also offers a thimble plate option allowing the slip-on TF-2 to be installed directly to a headwall or seawall. For higher backpressure ratings or to lower headloss while maintaining backpressure ratings, the Saddle Support Technology (SST) can be used in conjunction with the Series TF-2.

Red Valve Series TF-1 Check Valve

 

The TF-1 has become the preferred Tideflex Check Valve 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.

The TF-1 is ideal for manhole applications, such as junction boxes, diversion chambers and interceptors, where the invert of the pipe is close to the floor of the vault. These vaults are designed to maximize the available gravity head, thus the invert pipe is as close to the floor as possible. The TF-1 allows installation in such structures and is easily retrofitted to existing structures, often replacing failed flapgates. There is no need to break up the concrete floor to provide bottom clearance.
