The RK106 plastic wafer check valve features a minimal Face-to-face and a wide range of applications. The RK106 is simply clamped between the flanges and, thanks to the integrated sealing ring, does not require an additional flange gasket. In addition, the RK106 is available in many different Body, disc and sealing-ring materials. This allows the RK106 check valve to be optimized for your specific application. This valve can be supplied with return springs of various strengths, or without a Spring. This allows the opening pressure to be optimally adapted to the respective requirements and on-site conditions. We offer a wide selection of check valves—manufactured from a wide variety of materials and in many variable designs. Contact our sales office for comprehensive, free advice on this topic. You will find an overview of the many RK106 variants under “Technical data” and in the data sheet under “Downloads”.
