A valve system includes a conical valve body disposed in an engine gaseous fluid stream and having a first fluid passageway, where the conical valve body is a cone or a frustum of a cone. The system includes a fluid inlet conduit fluidly coupled to the conical valve body on an upstream side, a first fluid outlet conduit, and a second fluid outlet conduit. The first and second fluid outlet conduits are fluidly coupled to the conical valve body on a downstream side. The valve system includes a valve actuator operatively coupled to the conical valve body and that rotates the conical valve body, and a controller that provides a valve actuator command and thereby selectively flows the engine gaseous fluid stream through the first fluid outlet conduit and the second fluid outlet conduit.
