Hi
Last week I tested my Hydrafore SP10-57C spool on my Valtra and the pressure didn’t return near to 0, it stayed at 1000 psi in neutral.
So I think on Valtras the LS line as to be able to drain somehow trough the side of the valve.
The SP10-58D with a dual piloted check valve works right but the SP10-57C without check valve seamed to be smoother. So I will order a SP10-58C for testing.
@nut that’s a nice setup!
