Diverter Valve Troubles

[xanadu1797]

Have installed on my Kubota B26 a Surplus Center 6gpm Dual Solenoid diverter valve to serve at the front auxiliary hydraulics to power a grapple. So I've found that the grapple will work with the AG hoses hooked together in one configuration but not the other. When I switch to the non working configuration the grapple will close but not open. When I switch the quick couplers the grapple works fine but I have chatter on the curl circuit (plumbed to the surplus center block).
Oh, when I switch the Feed and Return lines to the Aux lines at the block, the same thing happens so I think that rules out the quick attach connecters up front.

I'm guessing this is a problem with the spool valves somehow but I can't get any farther. Thoughts?

Do you have a diagram or schematic for diverter valve? If nothing else maybe a couple pictures of the valve would help.

Sounds like your B26 has a 3-way loader valve and the ‘regen’ or the regenerative function of the loader valve is causing your issue.

Old thread, but still good info:

3 position valve-vs-4 position valve

I see this question come up alot, so I thought I'd make it a little more "searchable" The 3 position valve and the 4 position valve, both have what is known as a regenerative circuit built into the bucket dump circuit. First let me explain what "regen" is and why. When dumping a loaded bucket...

Here’s a schematic for the diverter

Anything I can do to fix this?
