Max. operating pressure (main port ①) bar 350
Max. permissible return flow pressure (main port ②) bar 210
Maximum set pressure 2) See command value/pressure characteristic curves on
Minimum set pressure at max. command value See charateristic curves on page 6
Maximum flow l/min 200 (with pressure stage 350 bar max. 100 l/min)
Hydraulic fluid See page 5
Hydraulic fluid temperature range °C –20 to +80 (–20 to +110 for fan drives)
Viscosity range mm2/s 12 to 800
Max. permissible degree of contamination of the hydraulic
fluid - cleanliness class acc. to ISO 4406 (c)
1) Caution! The maximum operating pressure is added up
from the set pressure and the return flow pressure!
2) Caution! The valves are factory-set. In the case of
subsequent re-adjustment, the warranty will become void!
3) The cleanliness class stated for the components must be
adhered to in hydraulic systems. Effective filtration prevents
malfunction and, at the same time, increases the service
