Medium Pressure (Open Center Valve)
(1) Main control valve
(2) Oil cooler
(3) Hydraulic tank
(4) Pilot manifold
(5) Retract solenoid valve "A3"
(6) Extend solenoid valve "A3"
(7) Main relief valve
(8) Auxiliary control valve
(9) Rotator motor
(10) Line relief valves
(11) Idler pump
(12) Auxiliary pump
(13) Pilot pump
(14) Drive pump Medium pressure is designed to provide oil to the work tool for tool rotation. An auxiliary valve is used to control the oil flow. This valve is shifted with proportional reducing valves that allow the operator complete electronic control over the tool rotation. An auxiliary pump is used to supply oil flow for medium pressure. A typical example of a work tool that will use medium pressure is a shear.Reference: Refer to Testing and Adjusting, "Work Tool Parameter - Program" for the tool control system to change the settings for work tool operation.Reference: Refer to Testing and Adjusting, "Medium Pressure: Default Value of Work Tool Parameters" for the Tool Control System to reference the factory settings.

Operation Lever List
Control Extension Retraction
Left Joystick Thumb Wheel Push Forward Push Backward Auxiliary Valve Extended
When the device for activation is operated in the extend position, proportional reducing valve (6) receives a modulated signal from the machine ECU. Proportional reducing valve (6) allows pilot oil to flow to auxiliary control valve (8). This shifts auxiliary control valve (8) allowing medium pressure oil from auxiliary pump (12) to rotator motor (9).Oil returning from the rotator motor flows through auxiliary control valve (8), oil cooler (2), and back to the hydraulic tank.The working pressure for rotation is limited by main relief valve (7).Auxiliary Valve Retracted
