The concept of the CADCON Iris Diaphragm Valve is similar to that of the iris of a camera. An aperture through which the material flows is created with a diaphragm. The aperture size is controlled to the extent of diaphragm movement around its own axis. Full closure of opening can be achieved in this design.

Cadel Engineering Works manufactures two basic versions, namely “CADCON Valve Single Lock” (CVSL) Series and the “CADCON Valve Double Lock” (CVDL) Series. These versions can be adapted to various industry applications based on minor changes in valve design.
