ABSTRACT:
An apparatus for managing and controlling fluid flow through a plurality of fluid conduits includes a chassis, a plurality of conduit occluders mounted in the chassis, each occluder for association with at least one of the plurality of fluid conduits and each being selectively actuatable between an open position permitting fluid flow through a respective fluid conduit and a closed position obstructing conduit fluid flow. A single actuator is mounted in the chassis, the actuator for adjusting the plurality of occluders between the open and closed positions. A roller cage is also mounted in the chassis for mechanically interconnecting the actuator to the plurality of conduit occluders so that the single actuator is mechanically capable of maintaining one of the plurality occluders in the closed position while maintaining another of the plurality of occluders in the open position.
