Introduction
The BM6X Series axial flow slam-shut
valve is an automatic shutoff appliance
suitable for installation as a safety device
in pressure reducing stations and on gas
transfer and distribution lines.
BM6X Series slam-shut valves are "wafer"
type with an off-center butterfly disk that
is mounted eccentrically.
The reduced face-to-face dimension,
typical of "wafer" valves, facilitates instal-
lation even in existing stations that are
not equipped with shutoff devices.
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 gas flow causes the slam-shut valve to
shutdown and can only be reset manually.
BM6X Series slam-shut valves use gas
from the gas line for operation and there-
fore does not require outside sources to
operate.
BM6X Series is in conformity with the
Pressure Equipment Directive
PED 97/23/EC and is classified under
Category IV.
