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.

A multiway valve for medical devices, chemical devices, etc. comprising a housing having an open front end and an open rear end, a plurality of tube channels defined between said front and rear ends through which individual tubes are adapted to be passed, each tube channel having a bottom tube support surface extending at least a portion of the distance between said front and rear ends and each having a second portion of the distance between said front and rear ends without a tube support surface so that the tube in the associated channel may be deflected below the level of said tube support surface, a clamp member movably mounted in said housing for movement backwardly and forwardly toward and away from each end of said housing and having a portion engageable with each tube when said clamp member overlies said tube at a place in which it is supported by said support surface, said clamp member being guided in said housing so that it is brought close enough to said support surface to compress the tube and at least reduce the flow therethrough, and guide means in said housing for guiding said clamp member for said backward and forward movement, said tube support surface in at least one of said channels is offset from said support surface of at least one of the other of said channels so that when said clamp member is positioned to close off at least a portion of the flow through one of the tubes it is located so that it does not effect the closing off of the cross-section of at least one of the other of said tubes, said clamp member being positionable in at least one position wherein at least one of said tubes is clamped off, in another position wherein at least two of said tubes are open and in a further position in which at least two of said tubes are shut off.
