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.). Ignition temperature >180 °C. Flame-resistant – containing water: Maximum operating pressure 210 bar Pressure differential <15 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 60 °C

Special application conditions for a safe application

Maximum ambient temperature:
In case of bank assembly, as long as only one solenoid is energized at a time, and in case of individual assembly: +70 °C
In case of bank assembly when more than one solenoid is energized at a time: +60 °C

The maximum temperature of the surface of the valve jacket is 120 °C. This has to be considered when selecting the connection cable and/or contact of the connection cable with the surface of the jacket is to be prevented.

Notice: The switching times were determined at a hydraulic fluid temperature of 40 °C and 46 mm²/s. Deviating hydraulic fluid temperatures can result in different switching times. Switching times change dependent on operating time and application conditions.
