ABSTRACT:
A multitube valve comprises a housing which has open front and rear ends with a plurality of channels defined between the front and rear ends each of a size to receive an individual tube therein and each including a support surface for the tube. A clamp in the form of a rotatable clamp roller has a journal extending outwardly from each side and it is engaged within respective clamp roller grooves which are defined in the housing on each side of the tube channels. The roller is movable by rotation along the grooves toward either the front or rear ends of the housing and it is of a size such that it cooperates with the support surface to compress the tubes therebetween and to at least partially close off the tubes when it is aligned over the support surface. The support surfaces are offset from each other in the longitudinal direction of the channels so that they operate at a separate time in respect to the positioning of the clamp for closing off the tube flow.
