Diaphragm single stage manual switchover board – CC283/CC383

The CC283 - CC383 switchover board for specialty gases is a manual switchover board. Ideally suited to insure gas supply from many high pressure sources of high purity non-corrosive gases with low flow (up to 25 Nm3/h). The device is dedicated to the supply of gas to analyzers and to the creation of controlled atmosphere in laboratories, control units, and for petrochemical applications. Thanks to the flexible and modular configuration of the switchover board, it is possible to manage inlet source, purging and outlet shut-off functions.
