INTRODUCTION

Scope of Manual

This manual provides instructions for installation, startup,

maintenance and spare parts ordering for the FL Series

pilot operated regulators. It also contains information for the

actuator, pilots, booster valves and lter.

Product Description

The FL Series pilot operated regulators are axial ow type

with a single seat and counterbalanced shutter.

The following versions are available:

FL: Regulator

MFL: Regulator - Monitor

BFL: Regulator - Slam-shut Device

Type SR, SRII and/or SRS silencers are also available.

All standard gas pressure devices (regulators and safety

shut-off devices) used in assemblies will comply to EN

12186 and EN 12279 standards.

Any accessories (e.g. pilots or lters) used on the Emerson

Process Management range of pressure regulators,

with or without built-in safety shut-off devices, must be

manufactured by one of the Emerson Process Management

companies and bear that label.

If this is not respected, Emerson Process Management will

not be responsible in the case of any inefciency.

In a conguration with integrated safety shut-off device and

pilot, when the maximum allowable pressures are different,

the slam-shut device is the differential strength type.

Europe, Middle East, and Africa Only

Type FL

PED CATEGORIES AND FLUID GROUP

The FL series regulators without built-in safety slam-shut

devices (FL and MFL) may be used as a stand-alone safety

accessory in a fail-to-close conguration to protect pressure

equipment under the Pressure Equipment Directive 97/23/

EC categories.

The technical features of the downstream equipment,

protected by this regulator, should be classied under

a higher category according to the Pressure Equipment

Directive 97/23/EC.

According to EN 14382, only in an integral strength and

Class A type conguration (in both over and under pressure

protection congurations), can the possible built-in safety

slam-shut device (BFL) be classied as a safety accessory

according to P.E.D.

The minimum PS between slam-shut device and pilot shall

be the PS of the safety accessory, complying to EN 14382

for integral strength types.

The technical features of the downstream equipment,

protected by possible built-in safety slam-shut device

(conguration BFL Class A and integral strength) shall be

classied according to the Pressure Equipment Directive

97/23/EC, see table 1.

OVERPRESSURE PROTECTION

The recommended safety pressure limitations 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 inlet pressure exceeds PS (see nameplate).

Downstream side pressure after safety shut-off device’s

intervention (in the built-in safety shut-off device

congurations) shall stay within the actual maximum

operating set-up range to avoid anomalous back pressures

that can damage the safety shut-off device’s pilot.

Equipment’s operation below the maximum pressure

limitations does not preclude the possibility of damage from

external sources or debris in the line.

Downstream overpressure protection shall be also provided

if the safety shut-off device outlet pressure can be greater

than the PS of the safety shut-off device pilot (differential

strength type). The regulators and possible built-in safety

shut-off device should be inspected for damage after any

overpressure condition and intervention.

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.

Ringbolts are designed just for handling of equipment weight.

Built-up sensing lines and pressure accessories (e.g. pilots)

shall to be protected by shocks or anomalous stresses.

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.

OPERATION

The purpose of this device is to protect the system against

possible overpressure, while keeping the reduction line in service.

The monitor controls downstream pressure at the same point

as the main regulator and is set a little higher than the latter.

Under normal operation, the monitor is fully open as it

detects a pressure value lower than it’s set value. If, due

to any regulator fault, downstream pressure increases,

when it exceeds the tolerated level, the monitor comes into

operation and adjusts pressure to it’s own set value.

The slam-shut device has a shutter and individual seat. It

functions independently of the regulator/monitor. The shutter

can only be hand-opened, by rotating the slam-shut reset

shaft counter clockwise. To keep the shutter open, the

actuator-pilot series OS/80X or OS/80X-PN is used. Both

series are designed to operate on maximum and minimum,

maximum only, or minimum only pressure.

When the system’s downstream pressure is at normal operating

value, the actuator-pilot remains set and prevents the slam-shut

reset shaft from turning by keeping the slam-shut shutter open.

When downstream pressure varies beyond it’s set limits,

the actuator-pilot releases the reset shaft and the shutter is

closed by the thrust of the spring.

Regulator

The Diaphragm Unit (permanently connected to the shutter)

divides the regulator control head into two chambers.

One of the chambers is connected to regulated

pressure (Pd), and the other to motorization pressure (Pm)

produced by the pilot according to pressure downstream.

Due to underpressure, the regulator spring acts on the

diaphragm unit and closes the shutter.

The shutter moves to an open position when the force

produced by motorization pressure (Pm) acting on the

diaphragm unit becomes greater than the force produced

by downstream regulated pressure (Pd) added to the load

of the regulator spring. The shutter stays idle when the

two forces are equal, under these conditions, downstream

pressure is equal to the system’s set value.

Any change in requested ow-rate produces a variation in

downstream regulated pressure and the regulator controlled

by the pilot opens or closes to deliver the requested ow-

rate while keeping downstream pressure stable.

Monitor

The Monitor or emergency regulator is used as a safety

device in gas pressure reduction systems.
