Electro-hydraulic control systems


  • The SY(H)DFE is an electro-hydraulic control system on the basis of axial piston variable displacement pumps for the variable:
    - pressure control
    - flow control
    - alternating p/Q control and
    - power limitation (optional)

The Rexroth-SYDFE is an electro-hydraulic control system based on an axial piston variable displacement pump for controlling pressure, flow and power without throttling losses in the energy line. The advantages are robustness, high efficiency, energy efficiency as well as a dynamic and highly accurate regulation.
