Valve stop for engine with exhaust gas recirculation

A butterfly valve (80) includes a body (81) with a bore (82) through which exhaust gas may flow and a valve member (84) rotatably mounted within the bore (82) for restricting flow through the bore (82). A stop (90) extends into the bore (82) to limit movement of the valve member (84) and prevent the valve member (84) from rotating to a closed position. The stop (90) defines a restricted flow position at which the valve member (84) is positioned between an open position and the closed position. An internal combustion engine utilizing the butterfly valve (80) is also provided.
