Now my next question is going to be what size of lines should I run to and from this valve? The PB lines that connect to the backhoe look to be 1/2". I assume that an 'open center' valve means that it has thru flow anytime it is in the center position so I should run 1/2" supply and return lines? My FEL has all 3/8" lines and I have been running 1/4" lines to the flail side to side slide cylinder.
