Vtek controller valve

So, you would need another valve such as: 1 Spool 8 GPM Prince MB11B5C1 DA Valve | Directional Control Valves | Hydraulic Valves | Hydraulics | www.surpluscenter.com and an adapter such as: P-Beyond & Closed Center Plug 8 GPM MB Valves | Valve Parts & Accessories | Hydraulic Valves | Hydraulics | www.surpluscenter.com

Great news! That should get you up and running.

Aczlan, that's exactly the valve I'm looking at.

Be aware you're going to have two relief valves now. The upstream valve will relief at 2000 per the prince valve description, and the downstream valve will relief at the lesser of the two valves assuming your existing relief is located on the loader valve. I'd adjust the new valve relief to 2250 or 2500, whichever your tractor is rated for so you don't lose lifting power. You'll need to borrow/buy a gauge and fitting if you don't already have one. Several good YouTube videos out there for reference if you need it.

I just figured I'd max out the new upstream valve and leave the existing loader valve alone.

I ordered the hoses and fittings that I needed from discount hydraulics last Thursday and they arrived today (Tuesday), now I'm waiting for the valve that I ordered from Northern Tool on Friday (ship to store, free shipping) and the power beyond plug that I had to order separately.

Once I have all the parts I'll have to weld/fabricate a mounting plate, mount the Add-a-grapple, and plumb it all in.
$700 for the grapple and about $350 for hydraulics and hoses, it should be totally worth it.

Re-read what I wrote. If your existing relief valve is located in the loader valve, your new valve with relief becomes the main relief. Don't max it out or you will have no relief protection when using your grapple.

 

[currierej]

Wouldn't it default to the the lower of the two relief valves?
Are you saying that the first valve could have higher pressure even though the second valve has a lower pressure relief?

Yes, exactly. Zero oil flows through the second valve once you activate the spool in the new upstream valve.
