Hydraulics..........

Is it possible to plumb this valve to use on a one way cylinder? I want to add it to my M Farmall to give better control than just pulling the rod. I can plumb it so I leave the pump running all the time and continuously circulate fluid through the valve, but this valve is for a two way cylinder. (It came off a log splitter when I put a self-cancelling valve on the splitter).

Do I just block one port on the top?

Thanks in advance.

Yes just plug one top port to operate a one way cyl.
t would seem to me that when he moves control to lower the one-way cylinder, that it will pressurize the now plugged port & dead head the pump, which does not seem like a good thing to do. What think?
 
Use one port to supply oil to the cylinder and T the other port into the return hose so that when you lower the cylinder your not running the pump on the relief valve.

I'll second the motion. DO NOT PLUG the port. Plumb it hack to the reservoir. If using the belly pump use the drain plug.

Just plugging the port will just cause the oil pressure to max out and open the bypass, heating the oil and use more horsepower.
 
I have a similar setup on an H, only dual hoses for a two way cylinder. That one has a T at the fill plug for the return. I planned to do this M the same.

My only question was about running a one way cylinder.
 
I had one of these on my M but didn't like how the return oil used the filler. It had to have the vent plugged to keep oil from blowing out the top.

I've since added live hydraulics and have the return oil going in the drain which I've tapped out to 3/4 instead of the 1/2 original.

Guess I don't have a pic of that, but here's one of my two spool valve.

Yes ,you can plug the non working port BUT you should use a plug that has a bronze filter in it.That type of plug will allow he cylinder to extend and retract with little resistance and keep debris from entering the cylinder.
 
GSVII is referring to how to use a two way cylinder for a single action purpose. Do not try this on
your valve unless you want to momentarily rust proof your tractor. Plumb the second port for down
pressure back into the return with a "T" as others have said.

xactly! Only I was about to say, unless you want to take a hot oil shower.
 

Sorry Goose,I read something into your post that wasen't there and thought you wanted to mod. the cyl.Since that valve came from a splitter,even while it's in neutral it'll be bypassing fluid so as stated fluid is going to have to be plumbed back to the "tank".
