ABSTRACT:
A throttling ball valve with an array of closed spaced horizontal plates secured across the flow passage through the ball. The leading edges of the plates are streamlined so that the flow stream will be divided into a plurality of laminar flow streams, each with a boundary layer across a surface of the plate. Energy is absorbed in the boundary layer phenomenon. The array of horizontal plates is preferably contained in a cylindrical sleeve which is inserted and secured into the cylindrical flow passageway through the valve ball.
