The cleanliness classes specified for the components must
be adhered to in hydraulic systems. Effective filtration pre-
vents faults and at the same time increases the service life
of the components.
For the selection of the filters see

Hydraulic fluid Classification Suitable sealing materials Standards
Mineral oils and related hydrocarbons HL, HLP NBR, FKM DIN 51524
Flame-resistant – Water-containing HFC NBR ISO 12922
Important information on hydraulic fluids!
– For more information and data on the use of other hydrau-
lic fluids refer to data sheet 90220 or contact us!
– There may be limitations regarding the technical valve
data (temperature, pressure range, service life, mainte-
nance intervals, etc.)!
– The flash point of the process and operating medium used
must be 40 K higher than the maximum solenoid sur-
face temperature.
– Flame-resistant – water-containing: Maximum pressure
differential per control edge 175 bar, otherwise, increased
cavitation erosion!
Tank pre-loading < 1 bar or > 20 % of the pressure differ-
ential. The pressure peaks should not exceed the maxi-
mum operating pressures!
