The implement control valve consists of seven control valves. The control valves are the boom, the rotator, the stick, the swing and the control valves for the harvester head.All of the control valves are controlled by proportional solenoid valves. The proportional solenoid valves are activated by the joystick controls inside the cab. All of the control valves are actuated by pilot oil. When the operator moves a function, the pilot oil controls the movement of the closed center valve spools. The valve spools are spring centered.All of the control valves have line relief valves except the swing control valve. The line relief valves are located on the swing motor.The following control valves have signal limiter valves:
Swing
Rotator
