Flow Divider / Combiner ValvesDIVIDER / COMBINER, CLOSED CENTREbcLocatingShoulder342Note: Closed centre valves have spring centred internal spools that provideblocked flow paths when centred. Centring occurs when the Port 3 flowis also blocked. This internal blocking isolates Port 2 and 4 from cross flow.4Port3Port2PortPort1daNot UsedWorkingPartsClearanceCapacityMin/MaxTypicalCartridgeModel CodeCartridge DimensionsCavity a b c dInstallationTorque(Nm)6-30 L/min.

Rated 45 +/-4.5% 21-25The maximum variation is at 350 bar differential between legs with the high pressure leg being the higher flow in dividing modeand the lower flow in combining mode.■■■■Maximum operating pressure = 350 bar.Pressure drop at maximum input flow = 24 bar; at minimum input flow = 1 bar.Operating characteristics cause the leg of the circuit with the greatest load to receive thehigher percentage of the flow in dividing mode. If a rigid mechanism is used to tie actuatorstogether, the lead actuator may pull the lagging actuator and cause it to cavitate.In combining mode, compensating characteristics will cause the leg of the circuit with the lowest load toreceive the higher percentage of flow. If a synchronization feature is not included, an additive accuracyerror will be experienced with each full stroke of the actuator.OPTION ORDERING INFORMATIONFS ✱ A – X A ✱NominalControl Flow Split Seal MaterialCapacityC 6-30 L/min.
