Blast Valve Type E 183-4" is a heavy duty valve which protects from blast
waves caused by outside explosions. The valve is normally open. If the air flow
rate exceeds the nominal value by approx. 80 %, the valve will close instantly.
It can withstand blast waves of 3 bar (42 psi) (infalling pressure). The valve
is tested and certified to the Israeli Standards 4570 by the Civil Defence Command
and the Standards Institution of Israel. |
