Abstract: An apparatus for controlling beverage flow includes a dispensing tube having a distal end. The apparatus also includes a ball plug configured for linear reciprocal motion between a first position and a second position so that the ball plug abuts the distal end of the dispensing tube in the first position and is separated from the distal end of the dispensing tube in the second position. A flow rate controller for compensation of flow in a fluid dispensing system includes a body portion and a first set of flow restricting nodes and a second set of flow restricting nodes formed in the body portion. The controller also includes a first channel formed in the body portion and configured to receive and partially surround a portion of a first fluid conduit such that the first fluid conduit is in contact with the first set of flow restricting nodes.
