Allen,
Is that valve in the lower picture what you call your priority valve? I've used a what appears to be the same thing as an adjustable flow control to regulate the speed on a hydraulic motor on a large saw infeed table at work. I don't know how that would work on a ps unit, since the aim is not speed regulation. Maybe the internals are different?

Yeah,

The power steering has to have right at 3 1/2 gallons of dedicated oil, meaning that it has to be first at the feeding trough or else the use of other equipment would "rob" from the steering and stop it.

Valve's "input" is plumbed right off the output of the pump and then it's leftover "exhaust" oil is used to power the rest of the hydraulic system.

What's the GPM of the hydraulics of your tractor? I've got a 730 Case, but I guess I never looked to see what the output is on it. Irv*

10 gallon at 1200 lbs I think?
