A levelling valve assembly for an air suspension system of a heavy vehicle is provided, including an air valve configured to allow air to either enter or escape from an air spring based on a position of a control arm of the air valve, and including a linkage rod assembly configured to translate movement between a sprung and unsprung mass of the vehicle into a rotation of the control arm to regulate a ride height of the vehicle. The linkage rod assembly further includes a spring and damper arrangement configured to dampen or block movement of the control arm not caused by a change in a mass loading of the vehicle.
