Backhoe control Valve replacement question

I have the Simplicity/Allis 9020/720 and the boom on the backhoe is drifting when I release the stick. It has 6 sticks to control everything.
I want to swap out this old control valve.
Anyone know what I should be "googling" to find a replacement?

The valves can be rebuilt. I would replace with joysticks if you decide to go that route after testing.
Some you can and some not. The ones on both my New Holland and my smaller loader controls were not rebuildable. There were no O-rings on the spools. They relied on a close tolerance fit and when they became scratched or worn there was no repair available.
