Abstract
A device for controlling fluid flow through a conduit includes a ball valve with a ball having a conduit terminating at an end thereof in an outlet orifice having a non-circular shape. The orifice shape is compound and may be selected to linearize the flow/ball angle relationship. The ball may be reversible to permit reversing the flow change dynamic and may also be a flow reducer.
