I could use some help plumbing multiple valves on my splitter build.

[topofthehil]

I am at the point where I could use some help plumbing multiple valves on my splitter build.
At first, I just needed a valve for the splitter, and then I thought that a log lift would be nice, so I bought a power beyond valve. Now, I would like to add a 4 way adjustable wedge.
I currently have a Prince 5000 power beyond valve to run the lift and a Prince 3000 valve to run the splitter. I plan to scrap the single spool power beyond valve and get a two spool with power beyond.
It’s less plumbing and more compact that way.
The first question I have for you is how do I connect the power beyond valves to the next valve?
Hard pipe, and if so what schedule?
Do I use unions?
Does someone make a short high pressure swivel nipple that will connect two valves together? I think the ports are 3/4" NPT.
I assume the last valve in the series is the should run the cylinder that does the splitting?

Thanks for your help.

You should be able to just take the output from Valve Assem #1 (usually labeled with a T for Tank) and run it into the pressure "P" port on valve assem #2. Then run T back to tank for hyd assem #2. Depending on your pump output you may not be able to run all of these things at the same time but I doubt you will with a log splitter. Pressure from your pump goes into "P" port in hyd assem #1. Hope this helps.

The ports are 3/4 female NPT. Grainger has about everything but they don't have a nipple that swivels. You can connect two valves with a Grainger part #2F449, which is a nipple with 3/4 male NPT on both ends. You would have to tighten the valves onto the nipple before mounting the valves, otherwise as you were tightening one end you would be loosening the other. You could also use a #2F449 plus a #5RKX6, which is a fitting that has 3/4 male NPT on one end and a swiveling 3/4 NPT female on the other end. It would then be possible to mount the valves before tightening the connection.

I have a Prince 3000 which is connected to a Prince 5200 by what looks like a regular steel 3/4 x 3/4 steel nipple and it is very short and works fine, but if there was ever a leak I would have to take both valves off to fix it.

The Prince 3000 is the first valve in line after the pump. It runs the log lift. The 5200 is an auto cycle valve and is next in line. I was thinking of putting a power beyond in the 5200 and connecting it to a Prince 3000 to run a 4-way wedge. I don't know if that is feasible or if it makes any difference in which position each valve is located.

There is no need to get complicated with the valve plumbing for a splitter. You can stack them outlet to inlet as pete said. Contrary to popular belief you can run more than one function at once when plumbed that way but prersures will be controlled by the lightest relief setting. Here is my splitter with a Prince Auto cyle first in line and two other valves stacked behind it.

thanks for all of the advice.
Butch, what did you use to plumb all of your valves together. a straight nipple? sch 80?

I used std black pipe fittings but my splitter doesnt need nor have high pressures either with that 6" bore. I think the relief is set around 16-1700. For the pressures that most are using Id go with hydraulic rated fittings, you can buy then with pipe threads from a hydraulic supply place.
