BVNO - Blast Valve

Overview

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.

  • Tested and certified to SI 4570 standard and/or compatible with requiernments of other shelter norms

  • Approved by civil defence authorities in different countries

  • Tens of thousands of company's products are installed in protected spaces
