PC200 - 7: The pressure setting for the unloading valve in the PC200 - 7 is typically in the range of [X] - [Y] bar. The exact value depends on the specific configuration and the requirements of the hydraulic circuit. For example, in a standard working configuration, the pressure might be set around 200 - 250 bar. This pressure setting is designed to handle the normal operating pressures of the hydraulic actuators such as the boom, arm, and bucket cylinders.
PC200 - 8: In the PC200 - 8 model, the unloading valve pressure range is usually adjusted to a slightly different value due to possible improvements in the hydraulic system design or the requirements of more advanced hydraulic functions. It might range from [A] - [B] bar. For instance, it could be set around 220 - 270 bar to accommodate the more precise control and higher performance demands of the newer model's hydraulic operations.
