ABSTRACT:
A fluid flow control valve includes a valve disk having a labyrinthine partition extending from its face. The partition describes a closed shape. The partition faces a valve seat. The range of control over the flow rate of a fluid is controlled by the length of the partition. Partition lengths are created by their shapes. Several complex shapes, giving rise to differing partition lengths are disclosed. An actuator urges the valve disk toward the valve seat to provide final control of the fluid flow.
