¹⁾	On all ports if P ≥ A; for design reasons
²⁾	At all ports
³⁾	See performance limits
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 data sheet 90220 or 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: The maximum pressure differential per control edge is 175 bar. Otherwise, there is increased cavitation erosion. Tank preloading < 1 bar or > 20% of the pressure differential. The pressure peaks should not exceed the maximum operating pressures! Environmentally compatible: When using environmentally compatible hydraulic fluids that are simultaneously zinc-solving, zinc may accumulate in the medium (700 mgzinc per pole tube).

With the electrical connection "K4", the protective earthing conductor (PE, grounded) is to be connected in accordance with the stipulations.
