widened output ange. Also available: SRS-R reinforced version; version with widened output but without a built-in silencer.
ATEX REQUIREMENTS
If the provisions of EN 12186 and EN 12279,
national regulations, if any, and specic manufacturer
recommendations are not put into practice before
installation and if purge by inert gas is not carried out before
equipment’s start-up and shut-down operations, a potential
external and internal explosive atmosphere can be present
in equipment and gas pressure regulating/measuring
stations/installations.
If a presence of foreign material in the pipelines is foreseen
and purge by inert gas is not carried out, the following
procedure is recommended to avoid any possible external
ignition source inside the equipment due to mechanical
generated sparks :
drainage to safe area via drain lines of foreign materials, if •
any, by inow of fuel gas with low velocity in the pipe-work
(5m/sec)
In any case,
provisions of Directive 1999/92/EC and 89/655/EC shall •
be enforced by gas pressure regulating/measuring station/
installation’s end user
with a view to preventing and providing protection against •
explosions, technical and/or organisational measures
appropriate to the nature of the operation shall be taken
(e.g. : lling/exhausting of fuel gas of internal volume
of the isolated part/entire installation with vent lines to
safe area - 7.5.2 of EN 12186 and 7.4 of EN 12279 ;
monitoring of settings with further exhaust of fuel gas to
safe area ; connection of isolated part/entire installation to
downstream pipeline; ….)
provision in 9.3 of EN 12186 and 12279 shall be enforced by •
pressure regulating/measuring station/installation’s end user
external tightness test shall be carried out after each •
reassembly at installation site using testing pressure in
accordance with national rules
periodical check/maintenance for surveillance shall be •
carried out complying with national regulations, if any, and
specic manufacturer recommendations.
DESCRIPTION
The FL Series regulators are used in reduction, distribution and conveying stations using suitably ltered natural gas.
They can also be used for air, propane, butane, LPG, city gas, nitrogen, carbon dioxide and hydrogen.
