The Iris Diaphragm Valve is a tube of flexible material fixed rigidly at each end. This tube is held in a mechanism which rotates one end through 180° relative to the other. When twisted in this way, the tube closes completely - enabling flow control and creating a diaphragm visually resembling the iris of a camera.
