PC200 - 7: The self - reducing valve block in the PC200 - 7 typically has a pressure regulation range from [X1] bar to [Y1] bar. For example, it might regulate the pressure from 100 bar to 300 bar. This range is set to meet the requirements of the different hydraulic functions and components of the PC200 - 7 model. The specific pressure settings can be adjusted according to the specific operation requirements of the excavator, such as light - duty operations (lower pressure) or heavy - duty operations (higher pressure).
PC200 - 8: In the PC200 - 8, the pressure regulation range may be adjusted to a slightly different range due to improvements in the hydraulic system design. It could range from [X2] bar to [Y2] bar. For instance, it might be from 120 bar to 320 bar. The wider or more precisely adjusted range in the PC200 - 8 allows for more advanced hydraulic operations and better control of the hydraulic actuators.
