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.
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.
