Important information on hydraulic fluids:

For more 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 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 50 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%

• Bio-degradable and flame-resistant:

When using hydraulic fluids that are simultaneously zinc-solving, zinc may accumulate (700 mg zinc per pole tube).
