I have been re-working my splitter over the last year and I was wondering about the valve I bought. It was listed as a 25 gpm valve with 1/2 work ports and 3/4 in/out ports. I also read in an earlier post that when you go to a 22 gpm pump you need to go to 3/4 lines. is the valve going to build up unwanted heat? I have all 1/2 inch lines now an am going to re plumb the ones i can in 3/4. The cylinder is already ported for 3/4 ( although it is only 3 1/4 x 18") everything else is also except for the work ports. And I plan on eliminating all the tight 90 degree fittings. Thanks.
