Important information on hydraulic fluids:
For more 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 process and operating medium used must be 40 K over 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 – containing water: If this hydraulic fluid is used, small amounts of dissolved zinc may get into the hydraulic system.

1)Connect the valve to the supply voltage only when this is required for the functional sequence of the machine.
2)Due to the surface temperatures occurring at solenoid coils, the European standards ISO 13732-1 and ISO 4413 need to be adhered to.
