Explosion Isolation valve
HIGH CERTIFICATION TEST
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
