The flow capacity of the main control valves is an important specification. It is designed to handle the flow rates required by the excavator's hydraulic actuators. Depending on the specific design and the number of functions it controls, the flow capacity can range from 100 to 300 liters per minute (L/min). The valve's internal passages and spool configurations are optimized to provide smooth and efficient flow control, minimizing pressure drops and ensuring that the actuators receive the necessary amount of fluid for proper operation.
