Cleanliness first, not as an afterthought
Every pump, motor and valve recommendation is checked against filter micron rating, differential pressure monitoring and ISO 4406 cleanliness goals so the drive package protects servo valves and bearings from early wear.
Hydraulic motor plus planetary gear interface notes
Specification sheets connect pressure, rpm and output torque with shaft pattern, mounting pilot, oil viscosity and service factor, reducing the back-and-forth that slows OEM release drawings.
Cartridge valve catalog support with test evidence
Valve choices are tied to cavity, cracking pressure, flow range and test bench notes instead of generic part names, making replacement and new manifold design easier to audit.
