Hydraulic Steering Unit 50cc, Load Sensing Dynamic Non-Reaction – Direct Replacement for Danfoss OSPB 500 LS (150-0106)
The BPB5 hydraulic steering unit is a direct replacement for Danfoss 150-0106 (OSPB 500 LS), offering a load sensing, non-reaction design with a piping-mounted priority valve connection for efficient integration into hydraulic steering systems.
Designed as an alternative to the Danfoss OSPB 500 LS steering unit, this model is suitable for mobile hydraulic steering applications requiring reliable load sensing performance and stable non-reaction steering control.
- Direct Replacement: Suitable alternative for Danfoss 150-0106 and OSPB 500 LS applications.
- Load Sensing (LS): Adjusts hydraulic flow and pressure based on the actual steering demand, ensuring efficient energy use by supplying only the required amount of oil.
- Non-Reaction: Prevents feedback from the wheels from reaching the steering wheel — the steering wheel stays stationary even if external forces act on the wheels.
