Diaphragm single stage automatic switchover board with manual reset - TD202
The TD202 switchover board is ideally suited to insure gas supply from many high pressure sources of high purity non-corrosive gases with low flow. 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.
Key advantages
  • Possible to connect up to 6 cylinders without using the purge line
  • Maintains purity: eliminates cross-flow mixing of supply sources
  • The automatic switchover board does not need to be reset to allow reversal of the cycle
  • Ready to install due with all components pre-mounted on a board
  • Can be equipped with a collection tube on the relief valve and purge outlet
  • Can be equipped with an outlet shut-off valve
  • Using contact gauges, the switchover board can also be equipped with an alarm box to indicate the source status
