Overpressures Blast Valves

We offer Overpressure Blast Valves to stop explosive blast waves from entering a bomb shelter as well as to regulate the air pressure in the shelter. The valve is normally closed and it’s opened to release air from the shelter while maintaining a constant overpressure and also to protect against explosive and implosive blast waves.

CPI manufactures a wide range of Overpressure Blast Valves:

• with a manual lock, in case of a sudden pressure drop
• with an integrated blower, to enable ventilation of the protected room in peace time

Features:

• Maintains a constant overpressure inside a shelter
• Protects against explosive and implosive blast waves
