B-Flap I-Explosion Isolation Flap Valve

Explosion Isolation Flap Valve B-Flap I - protective system.

Flow-Actuated Flap Valve type B-Flap I is designed as explosion pressure resistance equipment, which is able to
prevent a transmission of dangerous effects of explosion pressure wave and flames front to upstream areas. Product
has been designed in accordance with European Directive 2014/34/EU and certified by EN 16447 and EN 15089.

B-Flap I can be used in PULL acc. EN 16447 and PULL /PUSH or Reverse flow applications acc. EN 15089.

Description:
Welded construction in RAL 3000 painted carbon steel. Stainless steel without a surface finish only on special request.

Function:
In case of an explosion in the downstream equipment (e.g. dust collector) a pressure wave will force to close the Flap plate and lock in position. When Flap plate is closed it makes an effective barrier against approaching flame front. This prevent the explosion from being transmitted to upstream work areas.

  • Inside valve, zones 20 or 2
  • Outside valve, zone 21,22, no zone
