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 16447:2014.

B-Flap I must be used only for Pull configuration.

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, zone 20
  • Outside valve, zone 21,22, no zone
