Shock wave overpressure valve BVNO
BVNC overpressure valves are usually closed and open automatically only when internal excess pressure needs to be released. They provide important protection against internal overpressure caused by the explosion, while maintaining hermeticity under normal conditions.
Main characteristics:
-
Keeps excess pressure under control by automatically releasing excess air.
-
Running from pressure 50 Pa.
-
Available in different sizes according to the need for air flow.
Areas of use:
Perfect for civil defence shelters, military facilities, emergency options and critical infrastructure

Israel's M-type DU shielding doors
Israeli shelter Standard SI 4422 defines the specifications and characteristics of shelter doors for housing shelters, civil protection shelters, bunkers and other protected spaces. There are a variety of doors: from light doors in home security rooms to heavy-duty doors that withstand high explosion pressures and provide gas density, ballistic and fragment protection, burglar resistance and fire resistance. All doors are realistically tested with explosions and approved by Israel's Central Civil Protection Command (Home front Command).
