7065-SB Power Assist

7065-SB POWER ASSIST STEERING CYLINDER

The Kobelt 7065-SB power assist steering cylinder are controlled via inputs from fluid pressurized by a helm pump but are powered by a machine-driven pump.

This configuration enables responsive steering while requiring minimal human effort. In the case of a failure of the machine-driven pump the unit automatically switches to manual mode which allows for
steering via helm pump pressure only.

7065-SB cylinders consist of three main subunits which are the main cylinder, the control cylinder, and the valve.
