On the installed valve, back off the handle screw and un seat the handle and remove it. Take a 3/4" wrench and remove the cap. Pull out the shaft and selector cone. Drive out the pin and turn the shaft 180 deg and install the pin.

I was bouncing around the shop yesterday (low clouds and vis prevented flying) and took my spare valve apart. The above advice is 100% correct! I reversed the orientation of the "flat" relative to the nylon "ball" in five minutes. A very simple way to make the "machined D" handle work if you want to use it.
