In the WSM it says it is in the control valve body.I will try to attach a copy of the page.

Looks the same as my BX. It controls every thing on the implement side including the 3PT. If so; it is located on the HST case behind the left rear tire. I could be entirely wrong on this, may be worth checking.

Perhaps the easiest resolution to this issue is for the OP to post some pics of what he is actually looking at/seeing on his tractor from various angles. Another possibility is a call to a dealer with a mechanic that is familiar with the machine.
I have - prior to this thread - provided him with a couple of pics of the PRV and it's supposed location from the online Kubota parts manuals.
It is possible - looking at the various parts diagrams for the B7800 - the control valve and PRV for the 3PH are actually internal - IOW: inside the rear housing.

Jim,
That's actually great info ... and shows the value of having (or having access to) a WSM for equipment you own.
It contradicts what I previously told the OP, in terms of the orientation of the hex head plug capping the internals of the PRV.
The problem was that the exploded diagrams in the parts look up appear to show the PRV located in an incorrect location (left side rather than right), with an incorrect orientation (facing forward ... rather than facing right)
In hindsight I should have checked my WSM rather since I think it covers the B7800 as well as the B2910 ... rather than just replying on Kubota's online parts look up.
Too bad Kubota doesn't take greater care when making up the exploded views they use on the online parts look up.
