Red Valve Series TF-2 Check Valve
Overview:
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 It has been superseded by the TF-1 as Tideflex’s standard design, but remains available for customers who desire it for aesthetic reasons or space limitations.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.
Description:
The elastomer duckbill Tideflex Check Valve was specifically designed to eliminate operation and maintenance problems associated with flapgate valves – including corrosion, freezing open or shut, warping and clogging. The EPA has tested the Tideflex Check Valve for two years and found that it showed significant improvement over flapgate valves in terms of leakage inflow, debris entrapment, self-cleaning and marine fouling. Today, hundreds of thousands of Tideflex Check Valves are installed and performing reliably worldwide. Tideflex Check Valves have become the world standard for maintenance-free backflow prevention.
Red Valve Tideflex Technologies offers a full line of check valves for backflow prevention and custom-engineered systems for water mixing, aeration and effluent diffusers. Decades of proven field operation, research and development, and continuous engineering enhancements have all combined to make our check valves the most reliable in the industry today.
