The gpm part is what your pump puts out, not the valves "rating". If your pump puts out 25 gpm, the only problem would be getting that much through the holes if they're too small. This will just activate your main prv and bypass the oil.

If those valves dont have a screw and lock nut behind the cover, you can still usually shim them to a higher pressure with no problems. Pretty much all these bypass valves have a spring in them. This spring can be shimmed to increase the pressure much the same way as turning the screw on an adjustable one. The only thing is, if you really wanted to know what pressure you increased it to, you'd have to plumb in a guage.

I'm still a little vague on your "set-up" for the single action. Are you plannning on bypassing the oil in the "non-working" action? That would increase the heat build up considerably. If you want to simply send the oil back from the valve as you lower the loader, just run a short section of hose from the non-work port to the "out" side of the final valve body.

There are other ways to plumb this machine if you want to use the tilt while lowering the loader.

Also, I should say that I may have missed an earlier post or something, so we are talking about an open center system, right?
