The valve is held open either by airflow or proprietary locking mechanism. As a result, the VigiFlap valve can be used as an explosion isolation device for both the inlet and outlet of a vessel.
The Vigiflap Explosion Isolation Valve has been tested and certified for installation in any position with the process pipe installed on up & downstream sides of the valve, simulating REAL WORLD CONDITIONS. The valve’s unique inlet & outlet “straight through” design ensures very low static resistance and reduces dust accumulation. It is designed for use on the inlet and outlet sides of a filter or vessel. The VigiFlap Explosion Isolation Valve also complies with NFPA guidelines and is an ATEX Certified device for the containment of explosions.
