The present invention is an apparatus for directing a fluid stream from a source tube to a selected one of a plurality of outlet tubes in fluid flow communication with the source tube. Disposed within the source tube is an elongated sleeve, the sleeve having an inlet port and a single outlet port, the inlet port being in fluid flow communication with the source tube and the outlet port. The sleeve is longitudinally movable and rotatable within the source tube for selectively closing all of the outlet tubes and directing the fluid stream to a desired one of the outlet tubes. Apparatus is provided for rotating the longitudinally moving the sleeve.
