You should definately upgrade to R17-12 3/4" 3000psi on at least on that valve port going to the piston rod side of cylinder. (piston going in)

Contact Prince, and give them your pump data (cui per rev and rpm) bore diam, piston rod diam. They will tell you if you can get FULL performance with your pump-cyl combo. I guess you will end up with a 5 sec high speed cycle, because your regenerated flow will be higher than valve rated 25gpm.
Prince will also give you the local retailer for this valve. There was a 6 week waiting list on this valve when I called. Good luck!
