So how do you reconcile the extra port?
A1------Actuator port 1
B1------Actuator port 2

A2------Actuator port 3
B2------??

Thanks again.
This catalog page shows which ports should be pressurised and which should be vented for the different cylinder positions. We've found that it finds the intermediate position (Position 1 on those figures) a little better when ports 1 and 3 are both pressurised (since otherwise the second rod can float). Using this, we made a table of desired cylinder position and the desired port states for each (1 for pressurized, 0 for vented). Visual inspection of this shows how to plumb the solenoid valve to achieve this (and whether you need a single or a double, which way is the default position, etc.). If there is a valve port that is not used, it should be plugged to prevent venting the entire system when the valve is actuated.
