"Limited risk" version

The ATEX directive and some national regulations constrains industrials to take safety measures in silos to limit the effects of an explosion and to stop its propagation.

The STOLZ swing spout distributor has the advantage to insulate each non used outlet allowing :

  • to avoid any risk of cross contamination
  • to dramatically lower the danger of explosion transfer between circuits

Every outlet is fitted with an individual seal flap to avoid communication between the different circuits.

The opening of the outlet seal flap is individually controlled by a pneumatic cylinder.

Automation : control cabinet

  • a management automaton allowing to pilot and stop the swing spout at the required positions
  • a remote control by Profibus DP communication (AS-i or wired network supplied as an option)
  • a proximity control monitored by the automaton for a local control
