This steering orbitrol is the rotary metering valve that converts steering-wheel rotation into hydraulic flow to the steering cylinders. It sits between the steering column and the hydraulic supply lines, directing pressurized oil to the appropriate side of the steering actuator based on driver input. The component contains a spool and sleeve assembly that meters flow proportionally to steering angle, providing the operator with controlled response. Internal leakage past worn seals causes sluggish steering or a wandering feel at the wheel. As an original-manufacturer part, the housing and internal clearances match the original assembly's port geometry and flow curves, so no adapter fittings or flow-restrictor adjustments are needed during replacement.
