NOTE: This orbital valve is a load reaction type which allows physical axle forces (caster) to return the steering angle to its original center position when the driver releases the wheel after completing a turn. This return to center function is engineered to work with balanced (double-ended or cross connected single-ended) steering cylinders. It will work with a single-ended cylinder, but not as well.

The displacement of the orbital valve divided into the steering cylinder volume will determine the required turns of the steering wheel lock-to-lock (single ended cylinders will have different number of turns in one direction versus the other).
