OK, basic question for any a youse what work on hydraulics...
I know you can use a double acting cylinder with a single
acting valve by putting a breather in the unused port. But can
you run a single acting cylinder from a dual action spool by
plugging the other port? Would you need to add an extra relief
return before the valve for a standard dual action open center
valve, or would the OC or the valve internal relief take care
of that for you?

Working on a small project, and trying to minimize expense by
designing to what I can scrounge...

You can do it a couple of ways . Change the internal spool . Block the
handle so it will only move one way . Plumb from the unused port back
into your return line . Plug the port is fine , just hard on the relief
valve if you inadvertently shift to that port . Changing the spool is
the right way . So may different style of valves out there now I would
not say any advice other then direct from the manufacturer is gospel .
Most of them have free tech support so why not make use . Luck
