CoconThe Cocon series consist of three basic
configurations:
1) AS: Active regulator + Slam shut valve
2) AM: Active regulator + Wide-open
(Passive) Monitor
3) AMS: Active regulator + Wide-open
Monitor + Slam shut valve
All can be fitted with manual inlet valves
to block a stream or pneumatically actu-
ated inlet valves to function as additional
Emergency Shut Down, triggered by ei-
ther over- or under pressure.
Active regulator valve can perform open
or close action upon failure, depending on
requested characteristics.

CoconThe Cocon series underground pressure reduction unit consists
of several effective high pressure regulators, monitors and slam
shut valves combined in one easy-to-install cartridge, for use
in gas transmission systems, gas distribution networks and in-
dustrial take-offs.
Being installed underground, the Cocon will have a very low
impact on direct vicinity in terms of sound, looks and mainte-
nance/inspection nuisance. Downtime is reduced to a minimum
with the cartridge-exchange concept and maintenance can be
done under controlled environment in workshop, whilst the sta-
tion remains operational. Lockable lid makes for vandalism and
terrorism proof installation.
The Cocon series underground concept has demonstrated its
quality and usability for over 15 years in both industrial and ur-
ban areas worldwide.
Units consist of underground body with lightweight or
heavy-duty cover, one or two regulating cartridges (depending
on version) in parallel formation and external vent stack for safe
compartment ventilation and optional safety relief, supplied with
pilots and are suitable for an inlet pressure up to 100 bar(g) and
an outlet pressure range of 10mbar(g) up to and including 80
bar(g).
A mesh/felt filter is mounted onto the cartridge, and is thus re-
moved from the body simultaneously. The filter prevents debris
from reaching the valve seat where it could cause
damage and/or leakage.
The Cocon regulating unit is a double path
pilot controlled pressure regulator
featuring fast acting main line valve
(direct or P-action) and highly ac-
curate pilot (indirect or I-action). The
direct acting part is extremely fast,
while the pilot minimises set point
deviations.

controlled regulator and a slam type safety

using the pilot after which the regulator
-motorised by inlet pressure gas- will pro-
duce a levelled outlet pressure. Should the
outlet pressure rise above or drop below a
pre-set threshold, the slam shut valve will
close up, creating a bubble tight seal. The
slam shut valve can be fitted with proxi-
mity switches to allow remote monitoring.
Mechanical indicator to allow for local mo-
nitoring comes standard.
Cocon AMThe Active regulator + Wide-open (Pas-
sive) Monitor configuration features an
active, pilot controlled regulator like the
AS version, but instead of a slam shut
valve, a second regulator, the Monitor, is
fitted upstream of the Active regulator. A
monitor is an emergency regulator that

is activated immediately after the Active
regulator fails open. In contrast to other
safety devices, such as safety shut-off or
safety cut-off devices, the gas supply is
not interrupted if the Active regulator fails
open. The exterior construction of the
AM cartridge is uniform to the AS confi-
guration, enabling different configurations
to be installed in one Cocon body, thus
providing high flexibility in station configu-
ration.

The Active regulator + Wide-open Monitor + Slam shut valve configuration combines both of the above mentioned options, re-sulting in a complete pressure reducing stream with double pressure protection,
again in a externally uniform sized car-tridge, to be installed in the same Cocon body.

HPSDA High Pressure Shut Down can be fitted (single or double execution) to control a pneumatically operated inlet ball valve using inlet pressure. The ball valve actuator can be fit-ted with position indicator to allow both local and remote monitoring.
Double sealed compartment The instrumentation compartment
is protected against ingress of dirt,
moisture and debris by a double
seal, greatly reducing equipment
failure. The top cover, either light-
weight for easy access or heavy
duty for traffic run over, provides
the first barrier. Underneath is a
heavy duty transparent cover, allo-
wing local monitoring and inspec-
tion whilst maintaining a perfect
seal. The in- and outlet valves can
be operated without the need to
remove this inner cover.
