Wicket Gate

Wicket gates are a series of adjustable vanes that control the flow of water to a reaction turbine. Each vane, mechanically in parallel, is attached to an adjustable gate ring. Actuating the gate
ring either clockwise or counterclockwise positions the wicket gates to regulate water flow to the turbine. Variations of operating the wicket gates are dependent on many factors some including, axis of the turbine, available head, physical space, and turbine type.
