Tideflex Technologies was the original inventor and manufacturer of duckbill style check valve and has continued to enhance and refine the design and performance of this product.  The duckbill check valve is inherently a variable orifice device which changes it's effective opening area with respect to the internal pressure and mass flowrate through the unit. This flexibility can be incorporated into the design of the unit so that it will also perform as a variable flow nozzle. Enhancing velocity discharge and momentum within a fluid body is the key in achieving adequate mixing. Along with designing check valves for non-restrictive backflow prevention, Tideflex Technologies alos designs and manufactures mixing systems which utilize this variable orifice technology and the unique Tideflex Hydrodynamic Nozzles.

    Twenty years of proven field operation, research and development, and continued engineering enhancements have combined to make the Tideflex Model TF-1 today’s most reliable check valve. The bill design is formed in a curve that returns to a closed position every time, achieving the tightest possible seal for backflow applications, particularly at low flow rates. The eccentric flat-bottom design allows installation where the invert of the pipe is close to the floor, and the stronger engineered spine provides long-term performance while handling long-term water weight. No other manufacturers can produce this design with these state-of-the-art features.  When you specify the Tideflex TF-1 Curved Bill Check Valve, you’re guaranteed to receive a product with a proven record of maintenance-free backflow prevention.
