Tideflex® Check Valves for Backflow Prevention
Since its introduction in 1983, the Tideflex® Duckbill Check Valve has become a global standard for reliable backflow prevention. Engineered with a 100% elastomer construction and a distinctive duckbill design, it offers superior performance in wastewater treatment environments—effectively handling raw sewage, debris, sand and mud where traditional valves fail.
For low-profile or hard-to-access applications, Red Valve offers the CheckMate UltraFlex® In-Line Check Valve. This all-elastomer valve is specifically designed for stormwater, CSO, and sanitary sewer systems. Its flexible construction allows for low cracking pressure and minimal head loss, while delivering a tight seal to prevent unwanted backflow—even in low-flow conditions.
Tideflex® and CheckMate UltraFlex® Check Valves are available in a wide range of sizes and configurations to suit virtually any piping system. Installation options include slip-on or in-pipe connections, ASME flanges, thimble plates and fully customized mounting solutions.
