Additionally you should decide how you want to cylinder to work and what you consider safe.
A detent valve locks into either extend or retract (generally both), then kicks into neutral, fluid back to tank at the setting of the pressure relief valve. Which occurs at the end of stroke or in a nasty hard knot if your splitter doesn't have enough weenies.
This means, you don't have to hold onto the handle while the log is being split or retracting after the split and can be doing other things like getting the next log ready.
Some people consider that hazardous.
This is what I have on my splitter.
A auto return valve locks in extend, and goes directly into retract after reaching end of stroke.
So you don't have top pull the handle to put into retract.
More expensive, but this is now what I wish I put on my splitter and will change it out one day.
I want to load and split logs, not be pulling a handle.
