I have an old Yanmar Ym 2000D with a FEL, looks like a home built jobbie. It currently has a two spool valve body to operate the FEL. Well a friend gave me another valve body that is a three spool. It is slightly smaller in size but the fitting holes are of a very similar size. I’m wondering how I can calculate if/how much flow loss I would experience if I used it vs the original.
I would like to switch to the three valve as it would give me third function capability. Also the triple is newer and tighter.
