Steering priority valves

  • Steering comes first with our priority valves, for maximum safety on the road and on the job.

    A Danfoss priority valve will always give your steering system precedence. That makes it an important safety feature on load-sensing hydraulic systems where oil flow to the steering system and work hydraulics is supplied by just one pump.

    Features and benefits

    • Low pressure drop for high fuel efficiency, low noise and stable operation.
    • Available in static and dynamic versions. Dynamic flow gives a quick reaction time with no hard spot when initiating steering.
    • Optional pilot pressure relief valve for OLS 160 and OLS 320. 

    Application opportunities
    Steering priority valves add valuable functionality to forklift trucks (electric or combustion), tractors, telehandlers and backhoe loaders.

    Our priority valve range is designed with flexible mounting options to meet your system requirements.
