Above figure shows components composition of power steering system on the vehicle with the Orbitrol. This is an example of the simplest steering system. The oil from Pump flows into "P"-port of Orbitrol and then the quantity of oil in the proportion to the rotations of Steering Wheel flows into Steering Cylinders via "R"-port at right turn and via "L"-port at left turn. It is clear by this figure that there is no mechanical connections between the part of steering input (Steering Wheel, Steering Column and Orbitrol) and the part of steering output (Steering Cylinders,Linkages and Steered Wheels). Accordingly, there are many advantages for designing of vehicles. The Orbitrol is used principally for hydrostatic power steering systems of industrial vehicles, construction vehicles and boats, but it can be used for some servo-type applications or any applications where visual positioning are required.




ORBITROL is a hydrostatic - fully fluid linked - Power Steering Control Unit with epoch-making design. "Hydrostatic (or fully fluid linked)" means there is no mechanical connections between the steering control unit, the pump and the steering cylinders.

So it is very easy to design for a designer of each vehicles.


  •  Minimizes steering linkages :
  •  provides flexibility in design, reduces cost.
  •  Provides complete isolation of load forces from the control station :
  •  provides operator comfort.
  •  Provides continuous, unlimited angle control action with very low input torque :
  •  provides proportional flow to input steering speed.
  •  Provides a wide variety of control valve circuits (Spool / Sleeve) :
  •  helpful for the most suitable system design.
  •  Provides a wide selection of meter (Geroter) sizes :
  •  from 8 cm3/rev to 1000 cm3/rev.
  •  Provides highly reliable engineering :
  •  provides safety steering.
