Abstract: An EGR valve includes a flap is attached to a shaft and is rotatable to control exhaust gas flow through passage. The flap includes sealing ring for sealing against valve seat. A stepped diameter or collar on the shaft is disposed between first and second bearings to fix an axial position of the flap within the passage and relative to the valve seat. The collar fixes the axial position of the shaft to reduce axial movement of the flap and sealing ring relative to the valve seat.
