This leakageis directly proportional to pressure differential and inversely proportional to viscosity expressed in centistokes.Factory pressure setting established at blocked control port (deadhead).Pressure at port 3 is directly additive to the valve setting at a 1:1 ratio and should not exceed 210 bar.OPTION ORDERING INFORMATIONRegulated PressurePR ✱ B – ✱ ✱ ✱NominalCapacityControl** Adjustment Range Seal MaterialD 40 L/min.
