Re: control valves and cyllinder bore for digger
The Vario hyd system is much too big for what you're doing. The pump is Jung @ 0,3ml/rev & with the bl motor & belt reduction Vario is using = 1.2L/min, 18 to 22mm bores for 150 to 200mm+ strokes, 2.5/4mm plumbing.
T fittings for the boom.
It's not Wedico hyds.. Klaus Leimbach & son supplied hyd pumps, valves & cyls for Stahl, then wdc & as always for everyone else who wants to custom build.
I would say 14 to 16mm bore would be plenty for what you're doing.
FWIW, communicating with german companies... no spelling mistakes, no lol text, no slang, no run-on sentences, use exact words and keep it brief. Chances are they are using a translater program to help them understand your script. Pepper them with analytic specifics & pricing combos, they'll likely get annoyed & won't respond.
