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.

planetary gear and hydraulic motor interface

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 manifold test bench

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.
