    Important information on hydraulic fluids:

    For further information and data on the use of other hydraulic fluids, please refer to the data sheets above or contact us.
    There may be limitations regarding the technical valve data (temperature, pressure range, life cycle, maintenance intervals, etc.).
    The ignition temperature of the hydraulic fluid used must be 40 K higher than the maximum solenoid surface temperature.
    Flame-resistant – containing water:
    Maximum operating pressure 210 bar
    Maximum pressure differential per control edge 175 bar
    Pressure pre-loading at the tank port >20% of the pressure differential, otherwise increased cavitation erosion
