The rated pressure of the unloading valve is usually set at a specific value, for example, [X] MPa (megapascals). This value is determined based on the maximum operating pressure of the PC120 - 6 hydraulic system and the pressure - bearing capacity of the associated hydraulic components. When the system pressure reaches this rated pressure, the valve begins to unload the excess pressure.
（Pressure Adjustment Range）
The valve often provides a certain range for pressure adjustment to meet different operating requirements. The adjustment range might be from [minimum adjustable pressure] MPa to [maximum adjustable pressure] MPa. This allows the operator or maintenance personnel to fine - tune the unloading pressure according to the specific working conditions of the PC120 - 6, such as different load requirements during various excavation or lifting operations.
（Pressure Precision）
The unloading valve has a certain level of pressure - setting precision. The accuracy of the pressure setting can typically be controlled within ± [X] MPa. This precise control ensures that the valve responds accurately to the pressure changes in the system and provides reliable protection to the hydraulic components.
