Main control valve is an important hydraulic parts for an Excavator. It controls the action of the excavator.
The control valve function as follow:
(1) double pump confluent oil supply and increase the speed of moving arm. (only when the arm is raised)

(2) when the bucket is operated separately, double pump stations supply oil to speed up the action speed of the bucket rod.
(3) the motion of the arm is given priority, and the movement of the
arm will be given priority when the arm is carried out at the same time
as other movements.
(4) rotary priority, rotary and bucket at the same time, rotation will be a priority.
(5) negative flow control, give the main pump a negative flow signal,
so that the stem in the middle, the main pump displacement to the
minimum.
(6) walking in a straight line, when the excavator moves
forward or backward, other actions can be done at the same time, in
order to ensure the needs of special working conditions.
(7) the electric sensor can be configured to meet the needs of electronic control.
