FC-RBV-11-IW High Performance Blast Valve

FC-RBV-11-IW high performance blast valves are specifically developed for those applications where protection from extremely high over pressure and dual side protection are required. Its state of art design assures it provides the high impulse block rate against blast waves, which makes it one of the best safety solutions in the world.
FC-RBV-11-IW high performance blast valves could serve wide range applications including civil defense, nuclear power, OGP, etc.

FC-BRV-11-IW high performance blast valves are designed to be casted in blast walls.

+ Features&Benefits
  • High performance of blast resistance
Innovative tortoiseshell design to ensure high performance of blast resistance against blast waves with peak pressure more than 13 bar peak pressure reflected by long duration and multiple blast impacts and maintain all functions after blasts.
  • High performance of impulse block rate
Being able to completely close within 4 ms under 2 bar peak pressure reflected, which assures the approximate 100% impulse block rate.
  • Automatic-reset
Being able to retrieve ventilation function automatically after the blasts.
  • Double acting
Being able to provide protection from both positive pressure and negative pressure.
  • Excellent corrosion resistance
Being made of chemical-resistant materials enables long term maintenance-free.
