I cannot find anyone who makes a 2 spool valve with Power Beyond to replace mine and also fit into the space provided on the loader. Plus the ones that I think there is a possiblity to custom fit them, they are only 25 GPM not 26 GPM.

How about a picture of the loader control valve showing the mounting/space?

The first post, picture 3 shows the loader valve with no other room around it.

I saw that. The picture is too close to the valve to see anything. For me anyway.

Here are some more photos of the loader valve and plumbing. You can see the 1" OD input and output lines on the bottom of the valve along with the two working lines for the loader lift cylinders. On the top there are two working lines for the bucket cylinders. No room for me to buy another valve with power beyond unless the port was vertical.

Remember that the 26 GPM spec is for a NEW pump at full RPM. I don't think you will be red lining the engine while running and the pump is no longer new. It's probably closer to 22-23 GPM just from age and use increasing the clearances.

Also the flow spec are flow with a certain pressure loss. They will flow more than the spec, but will have more of a pressure loss.

Move the valve. Fab a new mount above the engine cowling, put any valve you want up there, lots of room.

Who makes a 2 spool valve that has the inlet and oulet on the bottom side of the valve? I can only find side and top inlets/outlets.

I don't know.

But even if all the ports are on the sides or top, you'd only need some hoses made up to route from the new valve to the existing hard lines, along with the proper adapters.

I'm sort of going through the same process myself. I've got a valve I want to replace, it lays flat with the work ports on top and the inlet and outlet are on the front edge. The valve I bought will mount (for now) on edge with the work ports coming out the side. It will look ugh buttly, but for now that's the way it's got to be. It'll mount flat when I fab up a new fixed point pivot mount for the joystick.

Nothing to see yet, still buying fittings and hoses. I'll have some.
