This invention discloses an axial multiport rotary valve capable of accomplishing the simultaneous interconnection of a plurality of conduits in accordance with a previously determined cycle, where any conduit communicates with no more than one other conduit at any one cycle step, or valve index position. The rotary valve comprises a hollow stator element and a rotor element inside the hollow interior of the stator element which rotates with a substantially vertical axis of rotation within the stator element, the surfaces of both elements being in the form essentially of a frustum of an inverted cone. Bed-line ports in the stator and rotor have a non-circular shape with a greater dimension in the vertical plane for higher capacities than provided in the known art.
