Product Description
The BM6X Series slam-shut valves are axial flow type and
are used in natural gas reduction, distribution and
transfer stations.
This product has been designed to be used with fuel gases
of 1
and 2
family according to EN 437, and with other non
st
nd
aggressive and non fuel gases. For any other gases, other
than natural gas, please contact your local sales agent.
The standard gas pressure devices (safety shut-off
devices - SSD slam-shut type) are those used in the
assemblies dealt with into EN 12186 and EN 12279 and
their use has to be under the provisions into
ENs 12186 & 12279.
In the safety slam-shut valves manufactured by Emerson
shall be used additional pressure accessories (e.g. controller
or filters) manufactured and labeled by Emerson.
Emerson will not be responsible for any possible inefficiency
due to installation of non Emerson production additional
pressure accessories.
When pressure containing parts of safety slam-shut device
(SSD) valve and controller have different maximum allowable
pressures (PS), the SSD is the differential strength type.
