BVNO air valve open in normal
BVNO automatic, normal valves are designed to be installed in ventilation openings to protect indoor areas from the effects of destructive blast waves. These valves are specially designed to provide ventilation while providing protection against unexpected overhead pressures. In normal condition, these valves are open, allowing continuous air flow, but in the event of an explosion automatically close to protect the interior.
Main characteristics:
-
A wide range of blast valves for different air currents. BVNO series contains valves with air flow between 50-2900 m ³/h (for one valve, multiple valves can be installed in case of increased air flow).
-
Rear pressure tolerance > 900 kPa (9 bar).
-
Very durable – withstand heat and corrosion.
-
Normally open blast valves can be equipped with a dust prefilter to remove dust particles and a special housing to direct air.
- Operating temperature -20 – +70 °C
- Mechanical strength not exceeding 12 g
Areas of use:
Perfect for civil defence shelters, military facilities, emergency options and critical infrastructure
