OSPB125 Hydraulic Orbital Steering

Productgroup: Steering Units

Productline: STEERING UNITS

Productset: OSPB steering units all versions from 50 to 199 cc/rev

Hydraulic Steering Unit 10 series is integral hydraulic steering unit, the valve body of rotary valve is integral structure, then the steering unit can integrate with cartridge valve, such as the pressure control valve of the integral system.

Hydraulic Steering Unit 10 series is widely used in the steering control system of different kinds of engineering vehicles, such as the steering system of many kinds of industrial and agricultural mobile machinery forklift, loader, road roller, tractor, combine harvester, and the ship helm etc. The steering unit can control the steering cylinder with bigger resistance force by inputting minor force; It’s easier , flexible and reliable; The integral check valve can prevent the system pressure oil from anti-vibration , and prevent from “hit-hand” during the steering operation; Integral pressure control valve can control the operation pressure and the shock pressure of the steering system.
