Question, do you have a 3 pt hitch, it has it's own seperate pump and when hitch is not being raised that fluid is added to aux valves. So, that would add some other possible solutions to your problem. When you say you have aux valve function when steering to stops that tells me your problem is in flowdivider however if you do have a hitch that flow from hitch pump should not be affected and still get you a flow to aux valves. What doesn't add up is you say you have aux valve function at low idle. I would take off the large hyd hose from pump to steering flowdivider valve at the valve end and look in valve to see if the orfice disc is in place in valve. I have seen them come out and sometimes just come loose and turn crossways in bore, eiether way, it allows all flow from pump to go to power steering but turning to stops will block flow and then send it to aux valves. Orfice is not a service item but I have made new ones by cutting off a slice from proper size bolt and ( can't remember exact size of hole) drilling a hole . About .125 I think. That could be determined though if orfice is actually the problem.
