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 \u2013 containing water:

  • Life cycle as compared to operation with mineral oil HL, HLP 30 \u2026 100%

  • Maximum hydraulic fluid temperature 60°C

1)Small amounts of dissolved zinc may get into the hydraulic system during use.
