Hydraulic valve assemblies for Every tractor, for every type of hydraulic system

I am replying to my last post in an attempt to make the multiple conversations here more understandable.

I made a couple of diagrams to make my questions more understandable:

How had i best use a baraki valve in my steering system? can i eliminate the control valve altogether like this next picture and use a baraki valve instead?

Or, do i need to leave that control valve in the circuit, and in that case, would this diagram work?

thanks again to all the help here!
