Important information on hydraulic fluids:
- For further 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 hydraulic fluid used must be 40 K higher than 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 … 100%
