Settings lower than the standard pressuremay result in lower reseat percentage.Counterbalance valves should be set at least 1.3 times the maximum load induced pressure.Back pressure at port 2 adds to the effective relief setting at a ratio of 1 plus the pilot ratio times theback pressure.Two check valve cracking pressures are available. Use the 1,7 bar check unless actuator cavitationis a concern.CB ✱✱ – ✱✱✱Cartridge DimensionscCavity a bLCInstallationTorque(Nm)60 L/min. CBCG – LJN T-11A 35,1 22,2 50,0 58,2 45 - 50120 L/min.
