PC200 – 7: The LS valve in the PC200 – 7 typically has a maximum operating pressure range of around 280 – 320 bar. This pressure range is set to handle the normal and peak load conditions during the operation of the excavator. The pressure – sensing mechanism is calibrated to accurately detect the load – induced pressure changes and adjust the hydraulic system accordingly. For example, during heavy – lifting operations, the pressure can reach the upper limit of this range to provide sufficient force.
PC200 – 8: In the PC200 – 8, due to possible enhancements in the hydraulic system design and the need to handle more powerful and precise operations, the maximum operating pressure range of the LS valve might be adjusted to approximately 300 – 340 bar. This allows for better adaptation to higher load – carrying capacities and more complex working scenarios.
