Diaphragm single stage automatic switchover board with manual reset & with balanced valve - CEN
The CEN switchover board is suitable for the high flow supply of non-corrosive industrial gases when high flow are required like for plasma TIG and MIG cutting and welding applications.
Key advantages
  • Possible to connect up to 6 cylinders without using the purge line
  • Outstanding pressure consistency with Balanced Valve Technology.
  • Ready to install for better productivity: all components are pre-mounted on the mounting panel
  • Reduced seat effort increases life of the regulator and reduces the ownership cost
  • Non-whipping filter on bottom inlet improves safety of the operator during the cylinder replacement
  • Can be equipped with an outlet 1/4 turn shut-off valve, with a collection tube, with an alarm box
  • Acetylene and Propane versions on demand
