AXIAL FLUID VALVES WITH ANNULAR FLOW CONTROL MEMBERS

摘要

Axial fluid valves having annular flow control members are described herein. An example axial fluid valve described herein includes an axial flow valve body defining a passageway between an inlet and an outlet. The example axial fluid valve includes a sleeve slidably received by an inner surface of the axial flow valve body and movable along an axis substantially parallel to a longitudinal axis of the passageway. The example axial fluid valve includes a linkage or a gear operatively connected to the sleeve to move the sleeve to vary a flow of fluid between the inlet and the outlet through the sleeve.
