One pump, 3 cylinders how to split it up?

[AKKAMAAN]

I would install a two spool valve with PB first inline, and then a Prince log splitter valve next.

I would advice having the most POWER using and frequent CV first in line, to minimize return flow power losses through the rest of PB valves.....That would put the splitter CV first in the series...Would of course require a PB capable splitter CV....

either feather the valve or install a needle valve to control the flow.

will still need to feather with needle valve, needle valve will make just make feathering more "responsive"...

I really don't understand what you are saying. If you mount a two spool valve with PB on the log splitter unit, the flow is going to the two spool valve first, and then to log splitter valve. One of the spools would work the log lift, and the other could would work the crane. If those spools are not being used, the full flow will go to the log splitter valve, with full flow.

since the PB require separate return from the PB host valve, it will be less back pressure, on return from splitter cylinder (which uses most of the flow gpm)

so when operating splitter cylinder a minimum of flow will enter and go through the down stream two spool valve.

if the two spool valve is upstream the splitter valve, all flow to splitter valve will have to go through the two spool valve, with more power losses as a result...

K??

Makes perfect sense. I was trying to get away from having to buy another valve but looks like it's time to find a pb single spool detent valve and make this one the first in line then run the pb to the 2 spool. If I would have been on here earlier I would have saved money and not given myself a headache on how to poor boy it. Thanks, Clint

While I'm spending the money on another valve I'll have to order a couple of needle valves and THEN it should be done and done right. Anybody need a priority valve and a detent valve? I'm soon to have extras..... thanks again. Clint

Take a look at this valve by Prince. It is an automatic log splitter valve. It has PB and is connected to a two spool valve downstream like this . RD-5200, and another two spool valve for log lift and wedge lift.

Here is a log splitter all set up for the two sets of valves. Look at post #26.

You could do the same thing.

If you use a regular log splitter valve the out of log splitter valve must go to tank, and is not recommended for a two valve setup.

I think once you start playing with hydraulics, you will always find a use for that priority flow valve. Put it with the spare parts.
