Resilient seat swing check valve to AWWA standard. For drinking water and neutral liquids to max. 70°C
AVK series 41 swing check valves come with both metal and resilient seats and are installed in pumping applications to prevent back flow. They are used for drinking water as well as waste water. The connection between disc and shaft is a flexible hinge that allows for a very precise disc and valve seat seal. All interior parts are either stainless steel or coated with drinking water approved epoxy, EPDM-rubber or hydrocarbon resistant NBR. The series 41 valves are available with either closed bushings or protruding shaft end where a lever with a weight or a spring can be fitted to mitigate pressure surges.
