I'll be going with the valve that JJ recommended in his last post.. Now I also have to order the Power Beyond adapter ?? Right?? and I don't want the 2 cylinders I am adding to go too fast so do I need 2 flow controller's ???

Install the valve with PB first.

Yes, you will need the PB adapter.

Your pump volume and lever management will dictate how much fluid is going to the cyl's.

If they are still to fast, then install a needle valve in the cyl line that you want to slow down.

Small cyl hoses will slow the volume somewhat.

A 2 in cyl with a 16 in stroke will be very fast with a 13 GPM pump.

Like bam. it throws the log at you.

A 3 in cyl will be half as fast.

With JJ's help, I also built a lift arm for my splitter. I used a 3.5" x 8" cyll. It performed perfectly. Not too fast not too slow. Today it lifted a stump that I could barely roll on to it. No problem. Didn't need an extra leg to off set the weight. it works awesome. My back feels great and I no longer have to toill away using my loader to lift heavy logs. Wish I would have done it 20 years ago.

Still waiting for my stuff to show up.. Today I worked on the stabilizer leg for the splitter and came up with a simple cantilever ratchet latch so I don't think I'll need the second cylinder for the table lift I'm adding.. I was wondering if the valve I ordered can be used for the splitter valve and lift table valve ?? I'll save the valve that is on it now for another project,, Surplus Center - 2 SPOOL 14 GPM PRINCE WVS21BB5C1 DA VALVE

Yes, you can use that valve as a log splitter valve. Except

It is a spring centered, when you let go the lever, it springs back to center.

You will have to hold the lever for extend and retract.

Might get a little tedious, when you could be getting the next log ready.

No.

Detent means that the lever will stay in a certain position, and fluid will continue to flow, or in a detent float position, the fluid is allowed to move in relation to the ground contour.

Detent could be a couple of balls in a groove holding the spool in position, pressure detent, or friction detent.

A log splitter valve has a detent in retract. You push the lever to retract, and the lever stays in detent until a certain pressure is reached, and then the lever returns to neutral.

Some valves could also have three position detent, where the lever can lock in three position.

The kit you show is for a spring center valve to convert it for a three position detent operation.

The three position detent will lock the lever in any of the three position.

If the pump is pumping, a detent lever will allow the fluid to flow through a work port to a motor. You would not want to detent a cyl, as when tthe cyl is fully extended or retracted, the relief would activate.

What is your intended use of a detent valve?

The below data is just some of the features that can be added to some valves.

Pressure Release Detent
1 Position Detent, Spool "out" Only,
Spring Center to Neutral
F**
Pressure Release Detent
2 Position Detent, Spool "in"
and "out", Spring Center
to Neutral
Spool "C" or "E" Only
G**
4 Position, Spring Center to
Neutral, Detent Spool In for
Float Position

I would like the detent to hold the return of the cylinder after the log is split.. Should I just get a bungee cord ???
