Abstract
An aircraft cabin pressure outflow control valve that includes a rotationally mounted valve gate and one or more flow influencing walls adjacent to or part of to the valve body. Each wall has a distal edge formed at a wall angle relative to one of the valve flow ports, and an inner surface that surrounds the valve gate when the valve is at or near it closed position. With this configuration, the effective flow area of the flow port varies substantially non-linearly over a range of valve positions.
