loader valve Yanmar 276D

[wesmann]

I've got a 276 D with a 1075 loader. Looking for info on the valve. The only marking I can find says Kontak. Like to find a schematic. Any info will help.

Problem being, Kontak Hydraulics became Commercial Hydraulics which is now Parker-Hannifin. They have really downsized their product offerings and/or sold off or liquidated many product lines.

Try Prince Manufacturing Corp. They have been known to be the competitor to many of these products and parts you are looking for ...

Not sure what info you want on the valve. It really is not that involved if chasing lines. If wanting the inner workings of the valve, well that can get very involved.
You have 2 main lines 1 pressure/supply and 1 return line.
The other lines will go to the loader functions and can be followed fairly essy.

Can't tell from picture but there could also be a power beyond line.

I think I have it puzzled out. There is an "extra" line in my valve that goes to a modular control valve for power steering. Planning to add a grapple. About to pull the trigger on a three spool valve recommended by winston1 in a previous post. It has a pby port...
Thanks for all the input.

3-spool valve is the elegant solution. I've read you can also tap a diverter valve into an existing line, maybe the bucket curl, to temporarily send its fluid to the new grapple. You might want to investigate this alternative.

I do not where you are in the process of adding the 3rd function for the grapple. The diverter valve system that California mentions is a solution lots of folks do.
Tractor Mike has a couple of YouTube videos from a recent install he did on his tractor. Worth watching if thinking of going that route or just to get info on it.
There are pros and cons to any 3rd function addition to your FEL. No one but you can decide which best fits your needs, but an informed decision on pros and cons helps you reach the best option for you.
Good luck on your process and you will love the grapple regardless of what you decide on a control valve.
