The setting procedure is; check the setting, remove the pressure, adjust the valve, check the new setting.■ Reseat exceeds 90% of cracking pressure.■ Select a spring range where the desired relief setting is approximately mid-range between the minimum and maximum pressureto ensure maximum valve repeatability.OPTION ORDERING INFORMATION200RD ✱ A – ✱ ✱ ✱0100 200 300Flow = L/min.4000200 400 600Flow = L/min.800NominalCapacityControl** Adjustment Range Seal MaterialB 45 L/min.
