Thanks Travis for catching it and didn't mean to steer you the wrong way Andy. The 4th valve DOES indeed move during functions.
No more answering guru questions for me till someone actually calls me one

Did your package arrive Andy? The reversing lead work out ok?

No need to apologize you were right on the purpose of the valve and just a little fuzzy on how it actually functioned. This was their cure to the pump having to start under a load. Where as other models with this size of pump use a gear reduction of some sort to start the pump more easily. I plan to put a 4:1 gear reduction motor on mine and go back to a 12V battery. As it sets though I have plenty of power and speed with the stock setup on 7.2V battery packs.
