Pressure pre-loading at the tank port > % of the pressure There may be limitations regarding the technical valve data differential, otherwise increased cavitation (temperature, pressure range, life cycle, maintenance Life cycle as compared to operation with mineral oil HL, intervals, etc.)! HLP to % The flash point of the hydraulic fluid used must be K higher Bio-degradable and flame-resistant: When using hydraulic fluids than the maximum solenoid surface temperature. that are simultaneously zinc-solving, zinc may accumulate ( mg zinc per pole tube). ) 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. Available filters can be found at RE, edition: -, Bosch Rexroth AG
