A ball check valve comprises a valve body chamber which includes an inlet opening, an outlet opening, and a ball that is free to travel within the valve body chamber. A valve seat is adapted for receiving the ball. A body clearance section is located downstream of the inlet opening. A bore section is located downstream of the body clearance section. Fluid flow is allowed to flow through the valve body from the inlet opening through the outlet opening, but fluid flow through the valve body from the outlet opening through the inlet opening is prohibited by the interaction of the ball and the valve seat. The inlet opening is smoothly contoured to urge fluid flow between the inlet opening and the outlet opening to be laminar in nature.
