A rotary valve system which includes of a pair of valve assemblies each of which has valve parts with flat faces which, when pressed together and rotated, provide valving action between various ports incorporated in one valve part of each assembly. The first valve part of each assembly contains a circular array of through openings, each of which is connected to a conduit. The second valve part of each assembly contains several passages which provide communication between various openings of the first valve part and valve apertures located in the second valve part of each assembly. The second valve part of one assembly also contains one or more passages which provide communication between members of one or the other array of openings. The valve system can be effectively used to automate operation of a gas or liquid adsorption system comprising two or more adsorption vessels, the number of vessels being equivalent to the total number of openings in either array. Use of the valve assembly in an adsorption system eliminates the need for many of the valves required in conventional multivessel adsorption systems.

[ What is claimed is:] [1.] A valve system having first and second sets of flow conduits and first and second valve assemblies, each valve assembly comprising first and second valve members having respective engaged surfaces relatively rotatable about a common center of rotation to provide valving action; said first valve assembly having a feed inlet and an exhaust outlet; the first valve member of said first valve assembly having a first set of equally spaced through apertures concentrically disposed about the common center of rotation of said first valve assembly with each aperture being in fluid communication with one conduit of said first set of flow conduits and the first valve member of said second valve assembly having a second set of equally spaced through apertures concentrically disposed about the common center of rotation of said second valve assembly with each aperture being in fluid communication with one conduit of said second set of flow conduits, said first and second sets of apertures having the same number of apertures; the second valve member of said first valve assembly having at least one feed passage means for providing fluid communication between said feed inlet and one or more apertures of said first set of apertures and at least one exhaust passage means for providing fluid communication between one or more apertures of said first set of apertures and said exhaust outlet, and the second valve member of said second valve assembly having at least one passage means for selectively interconnecting two apertures of said second set of apertures; and drive means for effecting relative rotation of the valve members of each valve assembly to enable rotationally cycled interconnection and fluid flow between apertures of said first set of apertures and said feed inlet, between apertures of said first set of apertures and said exhaust outlet, and between two or more pairs of apertures of said second set of apertures. [18.] An adsorption system comprising the valve system of claim 1 and an array of adsorption vessels each having a feed inlet end and a product outlet end and containing an adsorbent which preferentially adsorbs one or more fluids of a fluid mixture, wherein each conduit of said first set of flow conduits is connected to the feed inlet end of one vessel of said array of adsorption vessels and each conduit of said second set of flow conduits is connected to the product outlet end of one vessel of said array of adsorption vessels. An adsorption system comprising the valve system of claim 7 and an array of adsorption vessels each having a feed inlet end and a product outlet end and containing an adsorbent which preferentially adsorbs one or more fluids of a fluid mixture, wherein each conduit of said first set of flow conduits is connected to the feed inlet end of one vessel of said array of adsorption vessels and each conduit of said second set of flow conduits is connected to the product outlet end of one vessel of said array of adsorption vessels.
