Tideflex - Model Duckbill CTF - Series TF-2 -Check Valve
The CTF - Series TF-2 Duckbill Check Valve was the first duckbill check valve introduced by Tideflex. 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`s flared top and bottom design has been enhanced by the Series TF-1 Duckbill Check Valve. The TF-1 features a flat bottom that requires minimal bottom clearance.ds 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 TF-2 can also be installed on the O.D. of elliptical pipe and many arch pipes. Tideflex® also offers a thimble plate option allowing the slip-on TF-2 to be installed directly to a headwall or seawall.
