Sunset, I have asked Blackfoot the name of the valve, but he doesnt know what it is called either. I am going to try and get a name and number from him as to where he purchased his valve. The hydraulic store I believe he said was located in Montana, but he didnt give a name of the company and Montana is a pretty big state to search for something when I dont even know what I am looking for. Are all those question in your post directed at me, or just quotes from Blackfoot giz's post on the forestry forum.

Oldnslo, no, there isnt any hydraulic places close to me I can go to. I can get hoses made, but that is about it.
JJ, I actually was hopeing you would reply and maybe even give me a link where I could purchase what I am looking for. The system you decribed is a little more complicated than the one lever pull of the controlvalve function. Probably a lot more expensive as well. I think the valveing that Blackfoot used was only a couple or 3 hundred dollars.. I can do electric over hydraulic solenoid type valves and use lever or magnetic limit switches, Pressure switches and pressure reliefs, flow controls and such, but to many parts, to much plumbing and wireing and to many things that can fail. Actually, I think the valve I am wanting is some kind of divider valve as you suggested. I just have to figure out which one.
To answer some of the questions, the hydraulic saw motor is a rexroth, 2.5cuin motor.( much bigger than the danfoss77) It will be recieving 18+gpm at 2200psi. The motor will turn about 3150rpms. The same pump will be used to supply oil to the sawmotor, saw clamp and sawbar, which is why oil flow and pressure must be regulated independantly for each function. When control valve lever is operated, the clamp will engage the log to be sawed, holding it for cutting, then the saw motor will turn the sawchain and then the bar cylinder will slowly lower the bar into the log . Disengage the control valve lever and the motor stops, the saw bar raises and the log unclamps.
