Abstract
The valve body (1) houses a valve disc (2) mounted on a horizontal pivot (4) operated by a hydraulic jack linked to a lever attached to the valve disc. Under non flowing conditions i.e. when the water supply to the turbines has been cut off, there is no pressure difference across the valve so it can easily be closed by admitting high pressure water to the jack. A supply valve (11) is closed and another (14) opened, maintaining high pressure on the upstream side of the valve and releasing the pressure from the downstream side so creating a pressure difference across the valve which presses the disc (2) onto the seat (6).
