The present invention is directed to an EGR valve (10) having a housing (12) with a primary passage (14) and a secondary passage (16). A poppet valve (20) is used to separate or control the flow of fluid from the secondary passage (16) to the primary passage (14). The valve shaft (24) has a longitudinal axis (B-B) that extends through the primary passage (14) at a location other than the centerline axis (A-A) of the primary passage (14). Additionally, the present invention has a mixing furrow (30) located along the interior surface of the primary passage (14) that will cause gasses flowing from the secondary passage (16) to the primary passage (14) to swirl and mix prior to being introduced to the intake manifold of an engine.
