Couldn't open your pdf. I think I remember-some kind of ebay deal? nice looking valve. I got a Hussco 5000-C series(off junk fork lift) triple stack 2 double acting&1 single acting(I think? I hope) I got same questions about my valve too. But I'm too stupid to post pics
Going to take mine(when I get a round-tuit) to local mach/hyd shop w/questions and get a few fittings & maybe hoses. theyr'e a little high$ but they forgot more than I will ever know about hyd stuff. countryside hyd shop is invaluble in my opinion.
GOOD LUCK
