The excavator control valve is typically composed of multiple spools, valve bodies, springs, and other components, featuring a complex structure but powerful functionality. It enables independent control of multiple hydraulic oil flows, ensuring the excavator operates efficiently even under complex working conditions. For example, during actions such as digging, lifting, and rotating, the control valve can quickly respond to operator commands, coordinating the movements of various actuators to prevent operational errors or equipment damage caused by pressure fluctuations or insufficient flow in the hydraulic system.
