3-Spool Hydraulic Valve Control For a Root Grapple

[old and tired]

...What do you guys think?

Old and tired: Here is the link to Amazon page: Amazon.com: Monoblock Hydraulic Directional Control Valve, 3 Spool, 11 GPM, SAE Ports: Home Improvement

First, I don't know your tractor specs exactly... or how it works hydraulically. but that valve should work. It does list it as: "...Capable of closed center or Power Beyond (conversion plug required)..." And it list this for PB (Power Beyond):

Your tractor has an Open Center and this valve is for open or closed, so this is good. BUT the hydraulics I have dealt with, there is a port for low pressure return to the tank... it's possible that it's capped off - are there any marks (on either valve) that is marked with a "T" stamped into the casting?? THAT is how mine is setup - so I hesitate to to give you (possible) wrong information... since I don't know your tractor.

Did you get any paperwork with the valve? Can you post that? (Oops, you only have 3 posts... I think you need 5 to post photos... Make a few post saying "Hey"...)

old and tired: on the new valve there are 2 stamps. One is "P" on a side of the valve and the other is "T" on the opposite side. I assume I'll connect the load hose from the distribution unit to P and the return hose on T. There is no paperwork that comes with the valve and it is one of the reasons why I came here for advice. I live in Washington State and its been raining everyday for the last month and a half makes it difficult to go out there working on the tractor since I don't have a garage. It will be at least couple weeks before I can post pictures showing the progress for you guys. I'm grateful for all the help I received from this forum. You guys are awesome!

First, I knew nothing about hydraulics until TBN... I learned it all from here, TBN... I had to read it 3 to 4 times before I knew what everyone was talking about... I know what worked for my tractor...

P stands for pump (high pressure input) and T stands for tank (low pressure return to reservoir) any "PB" stamps? Actually, it might be stamped with a "C".... see this...

No PB stamp. However, there are N and T stamps where your sample pic indicates C and T. So, the N port on my unit is the PB port you've described, right? Same here I've learned everything from the internet, especially TBN from tractor standpoint. I'll do the same for others when come up to speed and gaining the experience.

I think you should be able to post pictures now. Pictures of your current setup will help us determine how best to guide you.

Looks good!

The valve should have come with a data sheet that tells you which port is which. If you didn't get that you should contact Summit Hydraulics and get one. I could not find it on the internet but I didn't spend a lot of time. If you guess wrong you could damage your tractor's hydraulics.

I think that you'd be better served to find a way to keep your high quality Kubota loader valve.

^ ^ ^ ^ What ericm979 said... I feel you are correct, but I would want to see how your tractor is set up right now.

Here's your valve, and my guess for power beyond (my GUESS) has a red arrow pointing to it. But again, we need to see how your tractor is set up...

Does your tractor have a hydraulic block like mine? Most likely not, if you could post photos of where your hydraulic lines from your FEL valve goes or comes from....
