ABSTRACT:
A gated proportional control valve is disclosed which allows both high-flow proportional dispensing and precision low flow. The design includes one or more controlled diameter and controlled-shape orifices in the control path, which, when both of the gate valves are opened, allow for consistent low flow dispensing. The gate valves can alternatively be opened or closed to allow proportional dispensing or valve closure. The invention is particularly useful in a fuel dispensing apparatus.
