Kioti CK3510 3rd Function Issue

[dfkrug]

Here is a diagram from the 3rd function valve instructions.

There is no PB port on your Summit H06 valve. You can't use the 'T' line to power the next valve in your series (the tractor AUX valve). That line is limited to 500psi, usually.

On my Kioti, I run a single diverter to the FEL to run my 4in1 bucket, and I run a long pair of hoses from the tractor AUX valve to run the 2-way front-mounted hydraulic mixer. In the latter case, I use only 1/4" hoses, but I run only at idle, and I still get some warm hoses.

3/8" should be large enough unless one of the adapters is an orifice fitting. I'm with LouNY that the schematic gives some confusion in the plumbing. Except that you bypassed the new valve and it didn't change the issue. The hoses are new so the "shouldn't" be an issue. Hydraulic hoses don't suffer a great deal of loss unless you are running long distances. Not enough that you would see it in your situation at least. The only thing that I'm struggling with is why the extra valve is added between the loader valve and the rear remote instead of after it. Although the loader valve may have a power beyond already in it so then it would make sense. I tried to find a schematic for your tractor but didn't have any success.

I would inspect your hoses closely. It would be less likely but still possible for someone who was careless to over crimp a hose end and restrict flow. I've saw it happen in #4 or 1/4" hydraulic hoses to the point oil flow was blocked. So it wouldn't hurt to take a good look at the crimps on the hoses. Big hoses aren't an issue because it takes a lot more pressure to crimp a 1" or #16 hose. Just something else to look at.

I believe the Summit valve is industrial style D03 subplate mounted valve so tank port is potentially rated to 3000 PSI.
