The TF-1 Curved Bill Tideflex check valve is designed with enhanced sealing to improve headloss across the valve. The valve is constructed entirely of rubber, making it immune to rust, corrosion and weathering. The new TF-1 design enables the check valve to handle long-term water weight and maintain its structural integrity. The spine is at a greater vertical angle, making the TF-1 able to withstand the cantilever effect when water is flowing through the valve. The TF-1 has lower headloss compared to the original TF-2.
