Important information on hydraulic fluids!

  • For more information and data on the use of other hydraulic fluids 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 hydraulic fluid must be 40 K higher than 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 HLP 50 to 100 %

Bio – degradable:

When using bio – degradable hydraulic fluids that are simultaneously zinc – solving, zinc may accumulate in the fluid (per pole tube 700 mg zinc).

Notice!

  • Only actuate the manual override using a rounded tool (Ø3+¹ mm) or special tool (separate order, material no. R900024943!)
  • Actuation of the manual override only up to a tank pressure of approx. 50 bar.
  • When the manual override is blocked, the operation of the solenoid must be prevented!
  • Actuation of the solenoids must be prevented!

Note

  1. The cleanliness classes specified for the components must be adhered to in hydraulic systems. Effective filtration prevents faults and at the same time increases the life cycle of the components. For the selection of filters see www.boschrexroth.com/filter
