VICKERS RV3 10 I 0 18/10

Compact sizing is one of the main reasons folks in mobile equipment work reach for the RV3-10 series. It's a poppet style valve, which naturally keeps the footprint small compared to spool-type designs, and the whole series was built around getting maximum flexibility into minimum space. For refuse haulers specifically, that's actually one of the listed target applications, so the fit and form factor should work well in tight installations without major bracket or hydraulic connections modifications.

It's designed for mobile and industrial applications like harvesters and refuse haulers, so it should be a good fit.
