B-Flap I-Explosion Isolation Flap Valve

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

Le clapet d’isolation actionné par le débit type B-Flap I est conçu comme un équipement de résistance à la pression d'explosion, capable d'empêcher la transmission des effets dangereux de l'onde de pression de l'explosion et du front de flammes aux zones en amont. Le produit a été conçu conformément à la directive européenne 2014/34/UE et certifié par les normes EN 16447 et EN 15089.

La B-Flap I peut être utilisée dans les applications PULL selon la norme EN 16447 et PULL /PUSH ou Reverse flow selon la norme EN 15089.

Description :
Construction soudée en acier au carbone peint RAL 3000. Acier inoxydable sans finition de surface, uniquement sur demande spéciale.

Fonction :
En cas d'explosion dans l'équipement en aval (par exemple, le dépoussiéreur), une onde de pression force la fermeture de la plaque à clapet et la bloque en position. Lorsque le clapet est fermé, il constitue une barrière efficace contre le front de flamme qui s'approche. Cela empêche l'explosion d'être transmise aux zones de travail en amont.

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