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 surface temperature. Flame-resistant – containing water: Life cycle as compared to operation with mineral oil HL, HLP 30 … 100% Maximum hydraulic fluid temperature 60 °C
1) Small amounts of dissolved zinc may get into the hydraulic system during use.

For applications outside these parameters, please consult us!
