Splitter Valve With LogLift valve

[Kevin in Ohio]

Kevin in Ohio - you don't happen to live in Medina do you?

I'm further south around Dayton.

Quick note, if you are using more than one valve, the splitting valve should be the last valve in line. I had mine before the log lift valve & when the pump would have to drop in to high pressure mode, the log lift would start raising on it's own. Spoke with Energy valves support & was informed to place the log splitter valve last & it would eliminate this problem. Yep it did.
For the log lift, you will want spring return in both directions. (No detentes)

Oliver thankyou for that important bit of info, something that I will have to pay attention to, but knowing that now It seems to contradict the clip 48 seconds in on that video clip
out of curiosity the problem that you had encountered with the log lift raising on its own could it possibly have bean eliminated by a check valve in the line to prevent back flow back to the valve.

kevin : I have been looking at some of your build pics on your splitter build over several cups of coffee & thoroughly enjoying the buid pics, still got plenty to look at,
it never entered my mind of making a dispersion tube on the hydraulic return like you did in pic 183, what i did was simply divert the flow at 45 deg, sideways & down, I am hoping this will work for me with a baffle midway in the tank to slow the oil flow down in the tank giving it time to cool down before going back through to the pump again.

You will HAVE to make sure your fluid level is as far above your return port as possible, otherwise you will be having a lot of foaming issues. Meaning, whipping air into the system. That is why they recommend the dispersion tube being at least mid way down. Even though your fluid coming back will be around 30 PSI, it will be moving and in volume.

My auto cycle valve is first on mine and I've had no problems. I asked My supplier and he said it didn't matter, just make sure the first one had a the Power Beyond Port. I got a PBP capable valve on both so I could change my design if needed. All a PBP is, is basically a fitting with an O ring that diverts pressure flow on down the line. No real "valve" at all.

technically it doesnt matter which is first, it will work either way, but from a flow perspective your highest flow valve should be first, that way theres minimal restrictions in that circuit (it doesnt have to flow throught an "up stream" valve causing restrictions)
who cares what the lift valve is getting for flow as long as its not kicking the pump into the second stage, youre going to want those work ports restricted to only about 3-4 GPM in the way of a needle valve or an orfice fitting, (needle valve is the best way as you can adjust flow as needed).
so best practice would be to put the split valve first, and all of the lower flow valves down stream. i think oliver's problem is more of an internal problem not a placment problem(nothing should be moving if the valve isnt being moved...)

I was under the impression that the main cylinder had to be first in line but was not 100% sure, had a look at SPLITEZ site & sent email about their valves, awaiting a respond hoping they do send to Australia as it would probably be cheaper buying from America including postage.
I can see now that I need to do something different for the return, similar to what you've done with the dispersion tube. might be able to do something with the inspection plate & make it serve two purposes

Nathon I am not high up in the ranks of hydraulics but all I can say is that I am glad that people like yourselves are there to pass on good knowledge as i enjoy fabricating things, & seeing the end results, I understand where your comming from with the needle valve, If I make an orifice more than likely will be trial & error thats if I get it right, where as needle valve get it right first go .
? Would you put it on the push line only or one on each line of the loglift.

it doesnt matter which side it goes on, just as long as you get the right needle valve which is the type that restricts flow in BOTH directions. some only restrict flow in one direction and are completly open in the other direction, and some have a built in check valve only allowing flow in one direction...
the one i have on mine is a Parker 3/8" (N600S) same as this one http://www.mscdirect.com/product/09636242, ill put a pic of mine in here, i believe i put mine on the retract port...

Thanks Nathon I have noted that valve down in my got to get list, kind of glad I am not jumping too quick to every idea that comes to mind while building this splitter as there is so much to learn & mistakes with the cost of steel & time these days can be a tab expensive, Just glad there's still guys out there in the metal industry that will give you steel for a slab of beer.
