Introduction
The BM5 Series slam-shut valve is an
automatic shutoff appliance suitable for
installation as a safety device in regulat-
ing stations and gas distribution piping.
The BM5 Series slam-shut valve is used
in natural gas, air, propane, butane,
LPG, city gas, nitrogen, carbon dioxide,
hydrogen regulating or distribution
installations.
The slam-shut valve is designed to
shutoff the flow of gas in the event of the
pressure rising above or falling below the
predefined levels.
The valve is a sleeve-type, therefore,
does not require any external by-pass to
facilitate the opening of the valve.
The valve can only be reset manually.
The BM5 Series is in conformity with the
Pressure Equipment Directive
PED 97/23/EC and is classified under
Category IV.
