Piston single stage supply board - CM454
Equipment for gas systems > Speciality gas equipment > Supply & switchover boards
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
