The inverter valves pressure calibration values should be 15% lower than
that of the overall maximum pressure valve, and 15% higher than the maximum operating pressure.

AD
This valve type is characterized by fully hydraulic operation, as it takes
advantage of the system pressure rise to cause an automatic and continuous
inversion of the utilization.The changeover takes place when the system pressure exceeds the inversion valves
calibration pressure, and therefore also in not predetermined positions. At cylinder stroke end, the overall maximum
pressure valve should be adjusted on a value 30% higher than the system operating pressure.
