The control valve operates based on hydraulic or electro-hydraulic signals from the operator's control lever or control system. Its main function is to guide pressurized oil to different actuators while maintaining optimal pressure and flow rate.


Key operational mechanisms:
Directional control: The valve moves its internal spool to open or close the oil passage, directing the oil flow to the desired actuator.

Pressure regulation: Safety valves and pressure compensators maintain system stability and prevent overload.

Flow control: Adjust the oil flow to ensure smooth and proportional movement of the hydraulic cylinder and motor.

Most modern excavators use load sensing control valves to adjust pump output according to demand, improving fuel efficiency.


Control valves are used in various excavator functions:

  • Boom, Arm, and Bucket Control – Directs oil to cylinders for digging and lifting.

  • Swing (Rotation) Control – Regulates hydraulic motors for smooth slewing.

  • Travel Motors – Controls left and right track movement.

  • Auxiliary Hydraulics – Powers attachments like breakers or grapples.
