This is the valve I have for my drive motor. Not saying you need this but this is what I have.
https://www.surpluscenter.com/Hydra...Motor-Valve-w-Flow-Control-9-7497-30.axdOn my machine I have a 2 spool pump, one flow goes to the motor valve one flow goes to everything else. You have a flow splitter so you have two flows also.
On the side of my hydraulics that goes to the steering and the lift
functions , the fluid enters a single spool valve that has power beyond that does the steering.
The power Beyond outlet goes into a 4 spool valve. Spool 1 is loader up and down, spool 2 is loader tilt, spool 3 is aux hydraulics 1, spool 4 is aux hydraulics 2. Then it's return goes to the tank return header.
The way this works is if I am actively steering I can't move the loader, but if the steering valve is neutral I have flow to the 4 spool valve and all my functions. I figured steering is more important than lifting.
On the drive motor side I only have one drive motor and one Valve. The flow goes to the valve, to the pump, back to the valve and to the tank. Applying this to you your down stream splitter is all downstream of the valve so this arrangement should work. I was under the pressio that your second splitter acts like a positive differential between the front and back wheels.
