A Komatsu PC50, 12,000# excavator.  There is a foot control valve that operates the offset for the boom and I would like to plumb a solenoid valve to run a ram.for the thumb or the offset alternately off the same in/out lines currently on the offset ram.  I think I need a two way, two port valve but I am having trouble finding the right one amongst all the valves out there. You need a two-position six-port valve.  Two position to select side shift or thumb.  Two ports for system in-out from the foot valve output, two ports for the side shift, two ports for the thumb.  The side shift and thumb both have double-acting cylinders.
