This listing covers the A4VSO71DR/10R-VPB25N00 pressure-controller version. Supply is as a new aftermarket replacement unit, quality checked before shipping. Because the full model code defines mounting, seals, shaft and ports, please send us your complete nameplate code before ordering and we will confirm the exact configuration.
Control: DR pressure controller
The DR control limits the pump pressure to the set value on the pressure port B. In its basic position the swashplate is at maximum displacement; when the set pressure is reached, the pump swivels back to approximately zero displacement and only delivers the flow required to maintain pressure.
- Pressure control set at factory to your requested value
- Pressure limitation adjustable within the nominal pressure range
Other sizes
Other A4VSO sizes and controls are available on request – sizes NG40 to NG1000 (40/71/125/180/250/355/500/750/1000 cm3) and controls such as DFR, LR, MA, EM, HS and DFE1. Send us your requirements.
