Abstract: A fluid injector system includes at least one injector for pressurizing and delivering at least one fluid from at least one fluid reservoir, a first flexible tube having a first lumen, a second flexible tube having a second lumen, and a valve assembly configured to selectively and reversibly compress the first flexible tube and the second flexible tube to open and close the first lumen and the second lumen. The valve assembly includes a first anvil moveable between a retracted position in which the first lumen is at least partially pen and an extended position in which the first anvil closes the first lumen, a second anvil moveable between a retracted position in which the second lumen is at least partially open and an extended position in which the second anvil closes the second lumen, and at least one eccentric cam rotatable to move the first anvil and the second anvil between the retracted and extended positions.
