The VigiFLAP is a non-return valve crafted to thwart overpressure or flame transmission from a downstream explosion (e.g., dust collectors, filters, cyclones) within the piping system. Operated by a lever arm, it can be employed at both the inlet and outlet of the filter, effectively isolating the filter from any explosion or overpressure event. During an explosion, the valve automatically shuts and securely locks, impeding flame propagation. The flap can be manually unlocked for maintenance purposes.
