Shift limits
The diagram below species the shift limits for valves with AC and DC solenoids. The specications
apply to a viscosity of 40 mm²/s and balanced ow conditions. The shift limits can be considerably
lower at unbalanced ow conditions. To avoid ow rates beyond the shift limits, a plug-in orice can
be inserted in the P-port.
