Technical Highlights
-
Full Displacement Coverage: Available in all major industry-standard sizes including A10VO18, A10VO28, A10VO45, A10VO63, A10VO71, A10VO100, and A10VO140.
-
Versatile Control Modules: Fully configurable with comprehensive control valve options, including ED72 (electro-hydraulic proportional pressure control), DFR/DFR1 (pressure and flow control / load sensing), DR/DRG (pressure control), and DG (two-position control).
-
Robust Design & High Pressure: Rated for a nominal operating pressure of 280 bar and peak maximum pressure up to 350 bar, ensuring precise volumetric efficiency even under continuous high-load operations.
-
Seamless Drop-In Installation: Built strictly according to global SAE and ISO flange, shaft, and porting standards, allowing for a zero-modification retrofit that drastically slashes OEM downtime and costs.
