Abstract

The penstock valve has a sliding closure member slidable across an opening within a frame to control the flow of liquid therethrough. A seal is provided between adjacent co-operating surfaces of the frame and the closure member respectively. The seal consists of a resilient portion bonded to one surface, and a bearing portion bonded to the resilient portion and adapted slidably to engage the other surface. A rigid insert is provided between the bearing portion and the surface to which the resilient portion is fixed thus to limit the maximum movement of the bearing portion causing compression of the resilient portion.
