    Important information on hydraulic fluids:

    For more information and data on the use of other hydraulic fluids please contact us.

    There may be limitations regarding the technical valve data (temperature, pressure range, life cycle, maintenance intervals, etc.).

    The flash point of the process and operating medium used must be 40 K over the maximum solenoid surface temperature.

    Flame-resistant - containing water:
    Maximum pressure differential per control edge 175 bar
    Pressure pre-loading at the tank port > 20 % of the pressure differential, otherwise increased cavitation
    Life cycle as compared to operation with mineral oil HL, HLP 50 % to 100 %
