Description: Steering control valve. 120cc/7.3 cubic inch displacement. Load reaction. All of the steering controls offered by PSC are load reaction. A load reaction valve allows axle forces to return the steering wheel to its original position when the operator releases the wheel after completing a turn. This return to center function is engineered to work in cross connected and balanced systems. It will work in a differential system, but not as well. The displacement of the valve divided into the steering cylinder volume will determine the required turns of the steering wheel to turn the steering axle full lock to lock.
