Control units & directional control valves

Control unit suitable for Bosch SR/SRZ control hydraulics

This main control unit is used in the tractor to control and regulate the hitch. With the control valve, attachments attached to the hoist can be raised and lowered continuously. The position control keeps a position (height of the attachment) preselected on the control lever constant. The traction control allows optimal use of the tractor's performance. Depending on the type of application, the control valve can also be used for mixed control of position and tension control. The control system constantly corrects disturbances automatically, making tractor driving much easier. The valve is very extensively equipped with additional connections for R and P, as well as continuous adjustment of P.The control unit is equipped with a lowering throttle, with which the lowering speed of the hoist can be adjusted.A sealing plug is included in the scope of delivery must be used in the valve if there are only 2 hydraulic connections on the hydraulic flange surface. The non-existent connection must be closed with the plug on the control valve. The sealing plug is held in its position by being flanged to the power lift.There is an additional connection for the return line at the front of the switch cap.Not an original replacement part!
