Abstract
A controlled flow filling system is used with a flowable product filling apparatus. The filling system includes a first, upstream V-track valve in series with a second, downstream umbrella valve to provide a substantially paraboloid liquid flow profile of the fluid while filling an associated container. The filling system is configured such that a substantial portion of the pressure drop associated with the flowing fluid occurs at the V-track valve cone to reduce spraying and loss of the fluid product at the umbrella valve. The filling system is used in a filling apparatus that uses pumps or a pressured gas blanket to provide motive force to drive the fluid through the apparatus.
