Product Description
The BM6X Series slam-shut valves are axial flow type.
The slam-shut valves in the BM6X series are used in natural
gas reduction, distribution and transfer stations.
They can also be used with air, propane, butane, LPG, city
gas, nitrogen, carbon dioxide and hydrogen.
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
Process shall be used additional pressure accessories (e.g.
controller or filters) manufactured and labeled by Emerson
Process.
Emerson Process will be not responsible for any possible
inefficiency due to installation of not own production
additional pressure accessories.
When pressure containing parts of safety slam-shut device
(SSD) valve and controller have different maximum allow-
able pressures (PS), the SSD is differential strength type.
