Patent ID: 8539982

Claim:
A flow though isolation valve, said isolation valve comprising: at least two opposing valve ends; a rotor disposed between said valve ends, said rotor being rotatable relative to said valve ends between a first position and a second position, said rotor having an outer surface having at least first and second openings on said outer surface, at least two surfaces each intersecting said outer surface, an internal rotor passageway having an opening on a first of said at least two surfaces intersecting said outer surface and an opening on a second of said at least two surfaces intersecting said outer surface; a first flow through conduit having an opening on said outer surface coincident with said first opening on said outer surface and an opening on said first of said at least two surfaces intersecting said outer surface, a second flow through conduit having an opening on said outer surface coincident with said second opening on said outer surface and an opening on said second of said at least two surfaces intersecting said outer surface, a first blank opening on said first of said at least two surfaces intersecting said outer surface, a second blank opening on said second of said at least two surfaces intersecting said outer surface, a first isolation valve pin having a first internal conduit; and a second isolation valve pin having a second internal conduit; wherein said first isolation valve pin is mounted for movement relative to a first one of said valve ends such that, when said rotor is moved into the first position, said first isolation valve pin is movable to engage said first blank opening, and when said rotor is moved into the second position, said first isolation valve pin is movable to engage said first opening on said first of said at least two surfaces intersecting said outer surface such that said first internal conduit is in fluid communication with said first flow through conduit, and wherein said second isolation valve pin is mounted for movement relative to a second one of said valve ends such that, when said rotor is moved into the first position, said second isolation valve pin is movable to engage said second blank opening, and when said rotor is moved into the second position, said second isolation valve pin is movable to engage said second opening on said second of said at least two surfaces intersecting said outer surface such that said second internal conduit is in fluid communication with said second flow through conduit.
