Blast Valves & Blast Dampers for Ventilation Ways Protection

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.

• 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.

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

Blast valves and overpressure valve for ventilation and air filtration systems of civil defence shelters, safe rooms, industrial applications and other types of protective structures.

Blast valves and dampers, overpressure valves, gas-tight valves, and other ventilation protection valves are designed for controlled air regulation and blast protection in gas-tight shelters and protected spaces. Our valves are certified and approved for installation as part of CBRN filtration systems.

• Blast valve - normally open valve, protects the inner space from blast wave effects.

• Blast dampers - blast protection devices for the protection of ventilation systems against blast effects.

• Overpressure valves - normally closed valve, designed for controlled release of air from the shelter and overpressure maintenance.

• Gas-tight shut-off valves are designed for isolation and airflow control.

To keep the shelter blast and gas-tight perimeter protected, different devices like wall sleeves and multiple cable transmitters (MCT) must be used. Such solutions are integrated into the concrete shelter perimeter to allow penetration of ducts, electricity and communication cables, water lines, and other systems while keeping blast protection and gas tightness.

• High-quality professional solutions

• Various sizes and options are available

• High blast rating and gas tightness

Ducting consists of air piping required for connection of different components like valves, blowers, and filters and more...
