Fluid Flow System and Fluid Control System

A fluid flow system configuration which simplifies the automation of fluid control, particularly for chemical processing systems where the minimization of fluid usage and processing speed are desired, particularly for the elution of radiopharmaceutical products. The fluid flow system comprises one or more input fluid containers for inputting fluid into the fluid flow system; a fluid flow control system coupled to the fluid flow containers, wherein the fluid flow control system controls and regulates fluid flowing through the fluid flow system; and one or more output fluid containers for receiving fluid outputted from the fluid flow control system. The fluid flow system integrates the use of single or multiple control reversing bypass valves as part of a fluid flow control system, whereby each reversing bypass valve can independently control flow direction forward, reverse, and/or bypass through the same flow path loop.
