Settings lower than the standardsset pressure may result in lower reseats percentages.Counterbalance valves should be set at least 1.3 times the maximum load induced pressure.P = bar2016128 Free FlowOPTION ORDERING INFORMATIONCW ✱✱ – ✱✱✱NominalCapacityVersion Control** Functional Setting Range Seal MaterialC 60 L/min.
