BOAS1 is a new type of open-core non-reaction type hydraulic steering gear, its built-in flow compensation device, with a unique servo magnification principle, can achieve magnification times :1:1.3, 1:5.1 :2, 1:2.5 flow magnification function, the equivalent displacement is basically not affected by the speed of the hydraulic steering wheel.
Displacement Range:100-500 mI/r
Steering Torque: 1.6-2.4N.m
Amplified Factor:1.3, 1.5, 2.0, 2.5
For power steering mode, it has the total flow amplifying function with the displacements from 100 ml/t to 500 ml/r. But for manual steeringmode, it has emergency operation function with the displacements from 80 ml/r to 200 ml/r (without servo-amplifying)
BOAS1 hydraulic stecring unit has the advantages of compact size, stability steering performance and emergency manual steering with smaldisplacements.It is widely used for the hydraulic stering system of tractors, combine-harvester, wheel loaders and other wheeled vehicles.
