A beverage dispense apparatus having one or more outlets for fluids to be dispensed, a fluid supply line for each fluid, each outlet being governed by a valve, and a valve actuator to open and close each valve. A flow sensor is positioned in each fluid supply line and connected to a control which controls the opening of its respective valve on receiving a start signal and actuates closing of the valve when the pre-determined amount of fluid flow has been achieved. Each valve includes a closure member movable in a passageway from a first position in which the valve is fully closed to a second position in which the valve is fully open. The closure member comprises a groove having a transverse cross section that increases in area in the downstream or upstream direction, whereby movement of the closure member from the first position towards the second position opens a flow channel through the groove.

1. A dispense apparatus for dispensing there from a diluent liquid and a concentrate liquid a desired ratio, comprising:a dispense valve body having a diluent inlet and a diluent outlet and a fluid passageway there between and a concentrate inlet and a concentrate outlet and a fluid passageway there between so that diluent and concentrate flow in a downstream direction from their respective inlets to their respective outlets, a v-groove regulator in each passageway having a central orifice, the central orifice having sidewalls and the sidewalls each having at least one tapered groove therein and each groove increasing in cross-sectional area in a direction opposite to the of flow of diluent or concentrate there through, a first rod extending through the v-groove regulator in the diluent passageway and having a rod end moveable by a first linear actuator to a fully extended closed position and a fully retracted open position and to a plurality of positions there between for regulating the cross-sectional area of the one or more tapered grooves through which the diluent can flow for regulating the flow rate thereof, a second rod extending through the v-groove regulator in the concentrate passageway and having a rod end moveable by a first linear actuator to a fully extended closed position and a fully retracted open position and to a plurality of positions there between for regulating the cross-sectional area of the one or more tapered grooves through which the concentrate can flow for regulating the flow rate thereof, a diluent flow rate sensing means for sensing the flow rate of the diluent and a concentrate flow rate sensing means for sensing the flow rate of the concentrate and both flow rate sensing means connected to a control means for inputting thereto flow sensing data, and the control means for controlling the operation of the first and second linear actuators for regulating the flow of the diluent and concentrate in response to the input flow sensing data.
