BVNO Blast Valves

BVNO Automatic action, normally open valves for installation on ventilation openings for protection of internal spaces against destructive blast wave effects. Blast valves are specifically designed for maintaining ventilation while protecting against sudden blast overpressures. These valves are normally open, allowing continuous airflow but automatically closing in the event of a blast to safeguard interior spaces.

Key Features:

• A large selection of blast valves for different airflows. The BVNO series includes valves with airflows in range 50-2900 m3/h (per valve, several valves can be installed for larger airflow).
• Returned Pressure Durability >900 kPa (9 bar).
• The valves are extremely durable and can withstand heat and corrosion.
• Normally open Blast valves can be equipped with a dust pre-filter for
  removing dust particles and special casing to dirrect air.

Applications:
Ideal for shelters, bunkers, data centers, and secure facilities requiring continuous ventilation with blast protection.
