for power steering mode, it has the total flow amplifying function with the displacements from 100 ml/r to 500 ml/r. but for manual steering mode, it has emergency operation function with the displacements from 80 ml/r to 200 ml/r (without servo-amplifying).

bqas1 hydraulic steering unit has the advantages of compact size, stability steering performance and emergency manual steering with small displacements. it is widely used for the hydraulic steering system of tractors, combine-harvester, wheel loaders and other wheeled vehicles.
