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.


A method for controlling flow volume through a fluid conduit system, comprising the steps of: (a) installing a ball valve in said conduit system, said ball valve having a control ball with a conduit therein terminating at an end thereof in an outlet orifice having a non-circular shape, said orifice shape determining the rate of flow at a selected ball orientation, the relationship between the angular orientation of said ball and fluid flow differing from that of a ball valve having a circular outlet orifice; (b) actuating said valve to position said ball...
