Piston single stage supply board - CM454

CM454 is a supply board ideally suited for pure gases for high purity applications to put vessels under pressure and for leak detection and purge of pipe work. The device is to be used in combination with a switchover board for the regulation of the emergency source during maintenance on the principal source. This avoids installing some extension and reduces the amount of leaking points.

Key advantages

Possible to connect up to 3 cylinders without using the purge line
Ready to install for better productivity: all components are pre-mounted on the mounting panel
Connectable to an alarm box using contact gauges
Equipped with a ¼ turn shut-off valve on the outlet
Collection tube available on the relief valve and purge outlet
Downstream regulation system can be decompressed by turning the hand wheel counter-clockwise
