A turbine includes a casing having a fluid inlet, a fluid outlet interconnected by a fluid flow path. A valve body is mounted in the casing including a plurality of flow passages within the flow path. Each passage extends from a passage inlet to a passage outlet. A control ring is movably mounted on the valve body adjacent the passage inlets. The control ring includes a plurality of openings formed therein. The openings are variably sized and variably spaced apart so that when the control ring is moved relative to the valve body, the passage inlets are closed and opened in sequence.
