1)For perfect system behavior, we recommend an external pilot oil supply for pressures above 210 bar.
2)qV nom ±10% with Δp = 5 bar/control edge; flow for deviating Δp see formula.
3)At port X or Y with stepped input signal from 0 to 100% (315 bar)
4)The cleanliness classes specified for the components must be adhered to in hydraulic systems. Effective filtration prevents faults and simultaneously increases the life cycle of the components. For the selection of the filters, see www.boschrexroth.com/filter.

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 40 K higher than the maximum solenoid surface temperature.
Flame-resistant – containing water:
Maximum operating pressure 210 bar
Maximum pressure differential per control edge 175 bar
Pressure pre-loading at the tank port >20% of the pressure differential, otherwise increased cavitation erosion
Life cycle as compared to operation with mineral oil HL, HLP 50 … 100%
Maximum hydraulic fluid temperature 50 °C
