Keruite supplies a full range of external, high-volume blast-resistant valves.
The valve is normally fitted to the external wall of the protected building. In normal operation it acts as a ventilation inlet or outlet.
When a destructive blast wave reaches the valve, it adjusts or shuts automatically in response to the overpressure, blocking the wave from damaging the building interior.
