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 50 K higher than the maximum solenoid surface temperature.
Flame-resistant – containing water:
The maximum pressure differential per control edge is 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 … 100 %
Maximum hydraulic fluid temperature 60 °C
Bio-degradable and flame-resistant: If this hydraulic fluid is used, small amounts of dissolved zinc may get into the hydraulic system.
