Abstract: A valve assembly for an exhaust gas recirculation system includes a housing defining an inlet bore and including a second interior surface defining a housing bore. The valve assembly also includes a valve seat and a valve. The valve includes a valve stem and a valve sealing member. The valve assembly optionally includes a baffle at least partially disposed in the housing bore. A first interior radius is defined between the valve stem and the second interior surface. A second interior radius is defined between at least one of the valve stem and the second interior surface, the valve stem and the baffle, and the baffle and the second interior surface. The second interior radius is different from the first interior radius and is configured to direct the flow of the exhaust gas in the housing bore to reduce swirl of exhaust gas in the housing bore.
