Shift Limits
The diagram below specifies the shift limits for valves with
DC solenoids. Valves with spool position “F” or “M” can
only be operated up to 70% of the limits. The specifications
apply to a viscosity of 40mm 2 /s and balanced flow

conditions. The shift limits can be considerably lower at
unbalanced flow conditions. To avoid flow rates beyond
the shift limits, a plug-in orifice can be inserted in the
P-port.
