Hydraulic fluid			see table "Hydraulic fluid"
Hydraulic fluid temperature range ¹⁾	NBR seals	°C	-20 … +80
Hydraulic fluid temperature range ¹⁾	FKM seals	°C	-15 … +80
Viscosity range		mm²/s	2.8 … 500
Maximum admissible degree of contamination of the hydraulic fluid, cleanliness class according to ISO 4406 (c) ²⁾			Class 20/18/15

¹⁾	Observe the "Special application conditions for safe application"
²⁾	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.

¹⁾	The switching times were determined at a hydraulic fluid temperature of 40 °C and a viscosity of 46 mm2/s. Deviating hydraulic fluid temperatures can result in different switching times. Switching times change dependent on operating time and application conditions.
²⁾	Suitable damping by user required
³⁾	If a suitable mating connector and a correctly mounted electric connection are used.

Maximum surface temperature ¹⁾	°C	140
Temperature class		T3
Certificate of conformity		No TC RU C-DE.ГБ08.В.02161

¹⁾	Surface temperature > 50 °C, provide contact protection.

The valve is to be installed in a way that no impact stress > 4 J can become effective.

In order to avoid dangers caused by static charge, the base and/or subplate on which the valve is to be fitted must be electrically conductive and included in the equipotential bonding.

Maximum hydraulic fluid temperature:
In case of bank assembly, as long as only one solenoid is energized at a time and in case of individual assembly: +80 °C
In case of bank assembly, if more than one solenoids are energized simultaneously: +65 °C

The maximum temperature of the surface of the valve jacket is 110 °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.
