VIGIFLAP
Flameless stainless steel ventilation
VIGIFLAP is a non-return valve designed to prevent the spread of excess pressure or flames resulting from an explosion in the downstream part of a pipeline system (dust collectors, filters, cyclones, etc.). The valve is held open by a handle and can be used both at the inlet and outlet of the filter. This allows the filter to be isolated from an explosion or excess pressure. In the event of an explosion, the valve closes and remains locked, preventing the spread of flames. The valve is manually unlocked.

To get our Atex certificate (N° INERIS 19ATEX0016X) according to the standard EN16447: 2014, we carried out our explosion tests in the most extreme conditions and as close as possible to the reality of the use of the product, with for example:
Protected Zone Pipeline :
All test carried out with a pipeline after the flap (picture1).
Flap locked open:
Automatic release of the valve by the pressure of the explosion
Floating flap:
During the test the flap valve is held fully open until the appropriate
time of release.
Vent panel on test vessel:
No open ports were used during test but vent panels were always used.
In few months our VIGIFLAP certificate will be improved with the following additionnal features Atex certified :
Size until diameter 1370mm
