BVNO blast valves are heavy-duty dual-action air valves designed for protection of internal space against blast wave pressure created by explosion
Blast valves are normally open valves which allow movement of air in regular operation and provide automatic closing action in case of incoming blast wave. The valves are designed for installation on ventilation openings or as part of the duct for protection of ventilation ways and internal spaces against destructive blast wave effects.
BVNO series of blast valves was developed by Arconik for use in civil defence shelters, bunkers, safe rooms and other protected spaces.
BVNO are automatic double action valves designed to protect from positive and negative phases of the blast.
The valves are extremely durable and can withstand a wide range of temperatures and resistant to corrosion.
Simple Installation in new structures with pre-installed wall sleeves or retrofit flanges.
The valves can be equipped with pre-filter for removing dust particles, special case with flanges or connectors to the duct.
UZS-1 Blast Damper
UZS protective section designed to protect ventilation devices of special-purpose buildings from the effects of a shock wave of long duration with a pressure up to 10 kg/cm² (1000 kPa).
MZS Blast Damper
MZS protective section designed to protect ventilation devices of special-purpose buildings from the effects of a shock wave of long duration with a pressure up to 10 kg/cm² (1000 kPa).
MZS Blast Damper Assembly (Flange Mounting Case)
MZS assembly includes MZS blast damper installed in the special metal casing that includes flange with opening of 200 mm diameter.
The steel casing protects the MZS blast damper from mechanical and weather damages with option to install electric heating wire preventing freezing.
Blast dampers - designed for shelters and blast protected industrial applications which require high amount of air for ventilation
Blast dampers are used in ventilation systems to prevent the blast wave through external walls into the building. They are designed with high ventilation capacity. The dampers can protect people and equipment from explosions or momentary pressure change (e.g. tornadoes, etc.). When an explosion occurs, the valve will close instantly under the action of the shock wave; when the shock wave disappears, the valve will be automatically restored. They are mainly used in refineries, oil & gas, nuclear power plants and some other facilities which are at risk of explosions. They are installed on the air openings (air inlet and air outlet) of the facilities.
