- Functional role
1. Flow & Direction Control: Distributes hydraulic oil to different actuators based on operator input (joystick commands), enabling precise movements of the excavator’s boom, arm, bucket, and tracks.
2. Pressure Regulation: Integrates relief valves to limit system pressure (max working pressure: 34.3 MPa / 350 kgf/cm²), preventing overload damage to hydraulic pumps and cylinders.
3. Load Sensing: Optimizes oil flow according to real-time load demands, reducing energy loss and improving fuel efficiency during light-load operations.
