Schedule 80 ball check valves have a spherical ball inside the valve body which works as a check to allow flow in one direction and close off to prevent back-flow. These only have a ball, no spring, so must be used in an upflow position to work properly. Unless specifically indicated, PVC is not NSF certified.
