Hydraulics for quick attach Grapple

[J_J]

Hold off on that as if you are wrong, you will block the hyd flow and the relief will go off, and cyl function will not work.

The purpose of the PB sleeve is to block the center gallery and route the fluid to the next valve.

I have a call into Prince and they are sending me the PDF, and I will fwd it to you.

From looking at the two spool WV valve PDF, the PB is on the top and the OUT port is on the bottom.

Did you order the PB sleeve from the same page as the valve?

Yes I ordered valve WVS 11B5C1 DA
And ordered the PB sleeve that goes with it.
I will take a picture of Valve and sleeve

Just to clear up somethings, is the PB adapter a hex screw or a fitting like the picture on the valve page?

Gary at Prince Hydraulics says that a hex screw goes in the bottom port and when installed, make that port an OUT port, and makes the top port the PB port for downstream flow.

Can you show a picture of the inside of the bottom port.

This is a PB sleeve adapter

I have the PB sleeve that lolls like fitting. Same as picture.

In most situations using a PB adapter, the port that the sleeve or hex screw is used becomes the PB out flow.

With this valve, it appears that after installing the PB sleeve, the sleeve fitting becomes the OUT port, and the top port becomes the PB pressure port.

You may have to reset the relief pressure to match up to the loader relief pressure.

The valve comes set to 2500 psi. You can set it equal to or below the tractor relief setting.

Thanks for all your help.
I will take your advice and use air test before I run fluid
Through it.
Will put PB sleeve in bottom out port. Make sure air comes
Through top port with lever in neutral.
If everything works correctly I will them connect hose from 3pt lift to top port.

I finally had time to take a few pictures of Valve.

I have a quick attach grapple on the bucket of my Kama tractor FEL. I just ran hoses back to one set of the rear remotes and use the control valve for that to operate the grapple. The grapple end of the hoses end in a bracket tack welded to the FEL cross member just behind the bucket. The hoses from the cylinder attach there by another set of quick couplers. This allows me to unbolt the grapple quickly and leave the plumbing in place. I would post pictures but I just removed the assembly to install it on my new Kioti DK55.

JJ got new valve installed and everything we exactly like you guided me. I have not connected to hoses to the grapple cylinders yet. I wanted to make sure FEL and 3pt lift still worked correctly, and it does. I was looking at quick connect couplers for the grapple hoses and i see one that for single acting sleeve set, a double acting sleeve set, and poppet. What are the differences and what do you recommend I use?
Thanks for the help.
