Your partner in outfall design

    There are up to 50 different hydraulic variations (Hydraulic Codes) within each nominal TFD size. This is achieved by changing the geometry and relative stiffness of the TFD. Red Valve has conducted extensive R&D and independent hydraulic tests to determine the jet velocity, headloss and open area characteristics of each TFD. With TFD’s, not only can the port quantity and nominal size be changed but the “Hydraulic Code” can be as well. This results in a hydraulically-optimized outfall diffuser.

    Red Valve engineers discuss the hydraulic goals of the diffuser with the consultant, then run the TFD hydraulic models to determine the size, quantity, and Hydraulic Code that will meet the hydraulic goals. The entire flow range is considered and jet velocity, headloss and effective diameter data is provided for all flows of interest. This data is required as input if environmental impact assessment models such as CORMIX or Visual Plumes is required for the design.

    Red Valve engineers also provide recommendations on TFD mounting styles and specialized configurations including wire-reinforced rubber risers and elbows.
