Swing check valve animation from AVK

the AVK series 41 swing check valves come with both metal and resilient seats. These valves are installed in pumping applications to prevent back flow and they can be used for drinking water as well as waste water. The disc is connected to the shaft via a flexible bush that allows the disc and valve seat to adjust exactly. All interior parts are stainless steel or coated with drinking water approved epoxy or EPDM. The series 41 valves are available with either closed bushings or protruding shaft ends where a lever with a weight or a spring can be fitted to mitigate pressure surges.
