You will need an open center, non load reactive, steering valve. With a 2x8 ram somewhere around 160cc per/rev. will be perfect for your requirements. I like a valve with around 200cc per/rev so I have rally car type steering. The orbital S&N sells has to be around 125cc per/rev. It's a little small for a 2x8 in my opinion. Just remember open center. Load reactive valves will work fine but objects pushing against the steering will be felt in the steering wheel.

Look up charlynn, danfoss, steering valve on the ebays.

I'm fairly sure I have the same one that Robin has. I'll look up the specs and post it for sale in the correct section..

It looks like the valve I have may be the fastest one commonly available. If this is the case I won't sell it as I only want one that is faster....I'm still trying to confirm what I have.

Whats the displacement on the valve you have? I find it hard to believe it is the fastest one as there are ridiculously big valves out there. If you mean its the biggest one a normal PS pump can keep up with then I would believe that.

I'm still trying to varify what I have. My steering is 5 turns lock to lock so if I do the math it works out to be the fastest valve that's sold at like poly performance or PSC....
I'm still not sure, I'm working on it.

Something is off on your math. If your cylinders are 2x8x.75 each, a 9.7 cu. in/rev valve would give you 4.75 turns lock to lock. A 12.0 would be 3.87 turns and a 15 would be 3.1 turns. This valve would give you 1 turn lock to lock.
So using this info. If I did my math right. (2'x8' ram) Then I should be looking for an orbital with a 7.5ci. That should be 3.3 turns lock to lock..

These guys have them, looks like prices must have gone up recently though.

Yeah you're right. It's either a 7.5 C.I. or 9.6 C.I....
My rams are 2"x7" with a 5/8" shaft.

That is a power beyond valve. If you were running rear steer that would be a good choice. If you aren't, then you either have to block the power beyond port or run it back to the pump res I can't remember which. It would probably be better to get a non power beyond valve.
Hijack...
This might be a stupid question, but can you use a ram that was used for hydro assist for full hydro by just changing the other needed parts???
Or, when I'm ready to go full hydro do I just sell all the hydro assist stuff and start over???
