The variable displacement motor A6V was designed especially for hydrostatic drives with secondary controls. A complete control assembly for a maximum swivel range of Vmax/Vmin=3.47 is fitted. Huade’s A6V motor are widely used in marine steering gear hydraulic system, slewing crane hydraulic system and adjustable pitch propeller hydraulic system.
