wagner 2 spool valve help

[railhead]

I bought a used Wagner (sworn to be good) 2 spool valve to replace a known bad one on my loader tractor. Boy i cannot seem to find the right combo for inlet and oulet for it. can anyone help or send me to help? Changing hyd lines when you know what you are doing is a pain, changing them over and over and over when you have no idea where they go just plain blows. Thanks for any help!

Are tractor & control valve open or closed system ?

open center. Is there a website that would have diagrams of wagner spool valves? normaly they have at least the inlet marked on them, this one does not have any thing marked.

You might try setting valve on workbench s/b 4 threaded ports on top. Fill all four holes with oil & check travel. I had a Wagner but I/O were stamped on valve.
