Abstract
A ball valve for a ball valve assembly having a housing with a housing sealing surface configured to selectively seal against the ball valve. The ball valve includes an outer sealing surface configured to selectively seal against the housing sealing surface, and a recessed surface set inward of the outer sealing surface and defining a reservoir within the outer sealing surface. As the ball valve rotates between open and closed positions, the reservoir establishes a gap between the recessed surface and the housing sealing surface that enables debris to pass therethrough and facilitate preventing debris accumulation between the ball valve and the housing sealing surface.
