Old and tired. That is the right one now. I was going say something before, glad I read all posts before I said anything.

Hi
Thank you very much for your help now i understand it the scheme was big help for me i will attach more pictures of valve here..
When i connect (air) on the IN port i get air on BYD all the time when i push the lever i get the (air) on the exits it depends on witch direction i push or witch lever on that exit i get (air) the BYD will bea constant flow of hydraulic ?
On the OUT i dont get any (air) but when i connect the air on OUT i get air on upper 4 exits ofc it depends on witch direction i pusch the leaver...
Video scheme of air flow

Hello Hamza,
Once you get the hydraulic adapter plate either bought or made on a machine shop, you can then use the picture shared by old and tired on post #5 as reference for your hydraulic connections.
Basically you'll have this, based on that picture:
Orange line (high pressure line) -> IN port on your valve
Grey Low pressure return -> OUT port on your valve
Green High pressure return -> BYD port on your valve. Now, you can remove that 90 degree fitting on this port if you need, but don't remove the bigger fitting where this 90 degree fitting connects to or the system won't work right. That's the Power Beyond (BYD) sleeve that provides flow for the rest of the system.
Looks like this:

Yes, hydraulic oil is constantly flowing in a circle through the whole system and dumping back into the main tank at high pressure. BYD (guessing) BeYonD port...
So the low pressure return, that valve's "Out"; is just to give a path for oil to drain back to the tank. When a hydraulic cylinder moves in one direction (gets pressurized), the oil in the opposite side of that cylinder (that doesn't get pressure), needs to drain (release pressure) that oil goes back into the tank under low pressure return to tank line.
When your dump trailer raises up, you are pressurizing that cylinder. When you let it down, that oil needs to be able to be able to release pressure and that oil needs to be able to flow back to the main tank. (hope this helps)

No problem, what I don't know is how to set up your dump trailer since they (normally) use a single action cylinder (vs. everything that uses Double Action cylinder). Which, single action is power up and gravity pushes it down.
I don't know if you need a special valve body or if the one you have would work fine for that??? Does anyone know? I guess you could use a double acting (power moves in both directions) for your dump trailer....

I run a double acting cylinder on my homemade dump trailer but I'm actually using it as a single acting cylinder, by just using one of the ports and the other has a breather on it.
I run this setup with my remotes, which are double acting. Now, there is a little bit of room on my remotes where I can lower the dump trailer without forcing fluid through the relief valve but it's a little bit slow. I can move the lever all the way, which will lower faster,and force fluid through the relief. That is perfectly fine and I do it at idle so it's not pushing all the flow and max pressure and it's only a very short time anyway.
On my setup, I don't really need to force fluid through the relief valve because I have an hydraulic winch on the front of the tractor that's plumbed before the remotes and I always leave it in free spool. So when I lower the dump trailer, I'm also running the winch in free spool at the same time, so it's doesn't put any strain on the system.
Hii
Me again
I do evrything like you sad i will putt pictures in this post but i have 2 more questions im consernd about it and i dont want to demage somthing :
1. I have one action cilinder on my trailer and it is only one pipe line going to it will it bring oil back thru the same line when i lover it ? Or i need do put some second pipe line ?
2. I have a backhoe there is a two pipe lines on it one gets the hydraulic to it and second gets the fluid back to tractor ?
Im woried about second line that geting back fluid where do i connect it on high pressure return or on the low presure return ? And i will put the T shape spliter or how do you call it on high/low presure return to get that exit for backhoe ?

First off, great job on the install!!! And nice clean shop area... Secondly, Sorry but I do not know the answers... I know very little about backhoes and even less about plumbing a single action cylinder with a Kubota.
I would suggest that you post another question asking "How to mount/use a single action cylinder with L3200 and a backhoe?" Link that thread back to this thread...
I'm afraid this thread might not draw enough attention from the right people. And the fact that this is a whole other question vs. just asking about Front hydraulics (which normally would imply, simple hydraulics for a grapple).
In the new thread, tell them about the dump trailer. Were you going to have the backhoe on at the same time as the dump trailer??? Or are you asking about plumbing with the backhoe lines??? (I'm confused, now)
The other reason to start a new thread about using a single action hydraulic cylinder is that I don't recall ever seeing one!!
Other than ptsg mention above... ptsg, so did you only run one line to your single acting cylinder and cap off (not use) the other line (dead heading it?). That still doesn't answer the backhoe question...
When the backhoe is not on, I THINK there is a bypass hose that is connected in place of the backhoe... (not sure if that helps).

In my case, since I'm using a double acting cylinder as single acting, I only run one hose from the remotes to the cylinder. The non used port of the cylinder has a breather. It can't be plugged.
In Hamza's case with the backhoe, he can simply plug the backhoe to the new remotes (nice and clean install btw) and hold the lever with a bungee cord or fabricate some kind of holder for the lever.
The only thing to keep in mind, is to make sure in whatever direction the lever is pushed, the fluid must enter the backhoe valve using through the P port of the backhoe valve, because there is the risk of feeding the backhoe using the Tank port which is a bad thing.
