I've got to have some hydraulics

[gator gar]

Is open center the same as open loop??? I'm looking at the 3 stage open center stackable valve bodies. There are open center, closed center and one that just shows the whole 3 lever valve set that doesn't state either or, but is design for 2 stage. Which one do I get???

Anyone want to translate what this ol boy is saying to me??? I just changed out my hot water heater, but that is about the extent of me diverting some fluid. How about  Pi r squared, will that give me a circumfrence or something??? Where is pineywoods, I need someone who speaks redneck.

I believe he is suggesting in a stacked control valve set you would want open center, the center returns to reservoir unless you push a control valve lever.  When the lever is pushed the hydraulic fluid is diverted to the load.

The P and T thing is throwing me off. Is that Port and tank??? Power and Tank???

Gar, I'm in DeRidder, la.  If it would help come get measurements and ideas form my lt-40.  i also have a valve body i salvaged from controls of a hydraulic boom mower I will share with you.  I think it has 5 valves in the bank. My 40 is stock hydraulics from woodmizer.  I do have a friend close by that added the loader in a clamp on kit from WM. If nothing else come thru here on the way to see Pineywoods.  Maybe you could get some good from my salvage

Buck, thanks for the offer. I'm sure enough liable to come see ya. I worked at Westvaco for about a month in DeRidder running some steam tracing for them. You're not that far down the road from me.
