Abstract

In accordance to one or more aspects of the disclosure an indexing track for controlling a dual valve assembly includes a plurality of interconnected pressure-up and pressure-down slots that define sequence paths to translate the pin and to actuate the dual valve assembly to a first position when the pin is in a first track position, to a second position when the pin is in a mid-track position, and a third position when the pin is in a third track position.
