INTRODUCTION
Scope of Manual
This manual provides instructions for installation, startup,
maintenance and spare parts ordering for the B/240 series
spring loaded regulators.
Product Description
The B/240 series regulators are spring loaded single seated,
whit counterbalanced valve disc.
They are usually supplied with safety valve and built in
lter and can be also provided with slam-shut controller for
minimum pressure, maximum pressure or minimum and
maximum downstream pressure.
The regulators of the B/240 series due to their operating
specications are mainly used in those system where
sudden capacity variations are required, or else, where the
cut-off of the gas distribution is controlled by solenoid valve,
such as for the feeding of burners.
They can be used with natural gas, and other not aggressive
gases.
The following versions are available:
B/242 • B242-AP: Regulator
B/249 • B249-AP: Regulator with slam-shut
Versions without relief valve available on request
Tightness cover versions available on request (e.g. B/249-D).
The standard gas pressure devices (regulators and safety
shut-off devices) 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.
Fail-to-open stand-alone regulators cannot be used as
a safety accessory according PED 97/23/EC to protect
downstream pressure equipment.
In the pressure regulators (with or without built-in safety
shut-off devices) manufactured by Emerson Process
Management shall be used additionary pressure accessories
(e.g. pilots or lters) manufactured and labeled by Emerson
Process Management.
Emerson Process Management will be not responsible
for any possible inefciency due to installation of not own
production additionary pressure accessories (e.g. pilots or
lters).
When pressure containing parts of possible built-in safety
shut-off device (SSD) valve and pilot have different
maximum allowable pressures, the SSD is differential
strength type.

P.E.D. CATEGORIES AND FLUID GROUP
According to EN 14382, only in integral strength type and
Class A conguration (when both over and under pressure
protections are set up), the possible built-in safety shut-off
device can be classied like a safety accessory according
to PED.
The minimum PS between SSD valve and pilot shall be the
PS of the safety accessory to comply the provisions of EN
14382 about integral strength type.
Downstream equipments, protected by possible built-in
safety shut-off device (in its Class A and integral strength
conguration) of this product, shall have technical features
such as to be category per table below according Directive
97/23/EC “PED”.

OVERPRESSURE PROTECTION
The recommended maximum allowable pressures are
stamped on the regulator nameplate.
If actual version hasn’t a built-in safety shut-off device, some
type of overpressure protection is needed if the actual outlet
pressure exceeds the actual maximum operating outlet
pressure rating.
Overpressure protection should also be provided if the
regulator inlet pressure is greater than the maximum
operating inlet pressure. Downstream side pressure after
possible built-in SSD’s intervention shall stay within the
actual maximum operating set-up range to avoid anomalous
back pressures that can damage the SSD’s pilot.
Downstream overpressure protection shall be also provided
if the SSD outlet pressure can be greater than the PS of the
SSD pilot (differential strength type).
Regulator operation below the maximum pressure limitations
does not preclude the possibility of damage from external
sources or debris in the line.
The regulator should be inspected for damage after any
overpressure condition.
TRANSPORT AND HANDLING
Established transport and handling procedures shall be
followed to avoid any damage on the pressure containing
parts by shocks or anomalous stresses.
Built-up sensing lines and pressure accessories shall to be
protected by shocks or anomalous stresses.
(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 & 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 & 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
• in case of selfop regulators diaphragm’s incidental failure
the amount of maximum ow to be vented can be calcu-
lated using the universal gas sizing equation, assuming
inlet pressure = regulator’s set-point, outlet pressure =
atmospheric pressure and venting hole DN on the regulator’s upper cover = 16 mm (Cg = 280).
• periodical check/maintenance for surveillance shall be
carried out complying with national regulations, if any, and
specic manufacturer recommendations.
SLAM-SHUT CONTROLLER
The following controllers are used with B/240 series
regulator with built-in slam-shut:
• OS/66 Series spring loaded controllers
ATEX REQUIREMENTS
If the provisions of EN 12186 & EN 12279, national regula-
tions, if any, and specic 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 shutdown operations, a potential external and internal explosive
atmosphere can be present in equipment & 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 inow 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 organizational measures
appropriate to the nature of the operation shall be taken
