EXCAVATOR AND CONTROL VALVE FOR EXCAVATOR
An excavator includes a hydraulic actuator driven by hydraulic oil discharged from a main pump to move a work element; a first control valve disposed in a center bypass pipeline; a second control valve disposed in a parallel pipeline; and a control device for controlling the movement of the second control valve. The first control valve and the second control valve are formed in a valve block of control valves, and the second control valve is disposed upstream of the first control valve.
