Hello Marco,

I ordered the valve on this site (Dutch):
SD5/3-P(KG3-120) 3X18L-AET - Hydraulicworld.nl de online specialist in hydraulische producten

The joystick and PB plug I ordered on this site (also Dutch):
Joystick LCB SD5/SD6 - SD95BLCB - Walvoil - KRAMP
Plug AE voor SD5 - SD95VAE - Walvoil - KRAMP

I dont think you can order directly from Italia, but I think that you can find something like this in your country.
