Information

AVK swing check valves provide easy access to maintenance simply by unscrewing a few bolts and lifting the bonnet assembly including shaft and disc out of the body. The disc is fully vulcanized with EPDM rubber and is mounted in a nylon bushing allowing it to move slightly horizontally and vertically to achieve compete tightness. AVK swing check valves are available with closed bushings and with free shaft for mounting of lever and weight/spring.
