conditions or variables are, contact your Emerson sales
office for assistance. Provide the product serial number
and all other pertinent information that you have available.

Inspection and Maintenance
Schedules

All products must be inspected periodically and
maintained as needed. The schedule for inspection can
only be determined based on the severity of your service
conditions. Your installation might also be subject to
inspection schedules set by applicable governmental
codes and regulations, industry standards, company
standards, or plant standards.

In order to avoid increasing dust explosion risk, periodically
clean dust deposits from all equipment.

When equipment is installed in a hazardous area location
(potentially explosive atmosphere), prevent sparks by
proper tool selection and avoiding other types of impact
energy. Proper care must be taken to avoid generation of
static electricity on the non-conductive external surfaces
of the equipment (e.g. rubbing of surfaces, etc.). Control
valve surface temperature is dependent upon process
operating conditions.

WARNING

Control valve surface temperature is dependent
upon process operating conditions. Personal injury
or property damage, caused by fire or explosion,
can result if the valve body surface temperature
exceeds the acceptable temperature for the
hazardous area classification. To avoid an increase
of instrumentation and/or accessory surface
temperature due to process operating conditions,
ensure adequate ventilation, shielding, or
insulation of control valve components installed in
a potentially hazardous or explosive atmosphere.

Control Valves

Installation

WARNING

D  Personal injury or equipment damage caused
by sudden release of pressure or bursting of parts
may result if the valve assembly is installed where
service conditions could exceed the limits given in
the applicable product literature, the limits on the
appropriate nameplates, or the mating pipe flange
rating. Use pressure‐relieving devices as required
by government or relevant industry codes and
good engineering practices. If you cannot
determine the ratings and limits for this product,
contact your Emerson sales office before
proceeding.

D To avoid personal injury, always wear
protective gloves, clothing, and eyewear when
performing any installation operations.

D If hoisting the valve, use a nylon sling to
protect the surfaces. Carefully position the sling to
prevent damage to the actuator tubing and any
accessories. Also, take care to prevent people from
being injured in case the hoist or rigging might
slip. Be sure to use adequately sized hoists and
chains or slings to handle the valve.

D Personal injury could result from packing
leakage. Valve packing was tightened before
shipment; however, the packing might require
some readjustment to meet specific service
conditions.

D Many rotary shaft valves are not necessarily
grounded to the pipeline when installed in a
flammable, hazardous, oxygen service, or
explosive atmospheres. An explosion is possible,
due to the discharge of static electricity from the
valve components. To avoid personal injury or
property damage, make sure that the valve is
grounded to the pipeline before placing the
control valve assembly into service. Use and
maintain alternate shaft‐to‐body bonding, such as
a shaft‐to‐body bonding strap assembly.

D Rotary shaft valves are designed and intended
for installation between flanges. Personal injury or
property damage may result from improper
installation. To avoid personal injury or property
damage caused by the sudden release of pressure
or bursting of parts, do not use or install rotary
shaft valves (including single lug constructions) for
dead‐end service.

D When ordered, the valve configuration and
construction materials were selected to meet
particular pressure, temperature, pressure drop
and controlled fluid conditions. Responsibility for
the safety of process media and compatibility of
valve materials with process media rests solely
with the purchaser and end‐user. To avoid possible
personal injury and because some valve/trim
material combinations are limited in their pressure
drop and temperature ranges, do not apply any

Safety Instructions

D103022X0GB

other conditions to the valve without first
contacting your Emerson sales office.

D Check with your process or safety engineer for
any additional measures that must be taken to
protect against process media.

D If installing into an existing application, also
refer to the WARNING in the Maintenance section.

NOTICE

Ensure that the valve and adjacent pipelines are
free of foreign material that could damage the
valve seating surfaces.

Maintenance

WARNING

Avoid personal injury or property damage from
sudden release of process pressure or bursting of
parts. Before performing any maintenance
operations:

D Always wear protective gloves, clothing, and
eyewear.

D Disconnect any operating lines providing air
pressure, electric power, or a control signal to the
actuator. Be sure the actuator cannot suddenly
open or close the valve.

D Use bypass valves or completely shut off the
process to isolate the valve from process pressure.

D Do not remove the actuator from the valve
while the valve is still pressurized.

D Relieve process pressure from both sides of the
valve. Drain the process media from both sides of
the valve.

D  Vent the pneumatic actuator loading pressure
and relieve any actuator spring pre‐compression.

D Use lock‐out procedures to be sure that the
above measures stay in effect while you work on
the equipment.

D The valve packing box might contain process
fluids that are pressurized, even when the valve has
been removed from the pipeline. Process fluids
might spray out under pressure when removing
the packing hardware or packing rings, or when
loosening the packing box pipe plug. Cautiously
remove parts so that fluid escapes slowly and
safely.

D Many valve parts that are moving can injure
you by pinching, cutting, or shearing. To help
prevent such injury, stay clear of any moving part.

D Never apply pressure to a partially assembled
valve.

D To avoid personal injury or property damage
caused by uncontrolled movement of a valve
bonnet, loosen the bonnet by following these
instructions: Do not remove a stuck bonnet by
pulling on it with equipment that can stretch or
store energy in any other manner. The sudden
release of stored energy can cause uncontrolled
movement of the bonnet. Loosen bonnet nuts
approximately 3 mm (0.125 inch). Then loosen the

English

Safety Instructions

D103022X0GB

body‐to‐bonnet gasketed joint by either rocking
the bonnet or prying between the bonnet and
body. Work the prying tool around the bonnet
until the bonnet loosens. If no fluid leaks from the
joint, proceed with bonnet removal.

D As you remove parts, such as valve shafts,
other parts, such as disks can fall from the valve
body. To avoid injury from falling parts, be sure to
support parts as you disassemble the valve.

D Personal injury could result from packing
leakage. Do not scratch the drive shaft or packing
box wall while removing packing parts.

D Check with your process or safety engineer for
any additional measures that must be taken to
protect against process media.

service conditions could exceed the limits given in
the product instruction manual or the limits on the
appropriate nameplates. Use pressure‐relieving
devices as required by government or accepted
industry codes and good engineering practice.

D Always wear protective gloves, clothing, and
eyewear when performing any installation
operations.

D Disconnect any operating lines providing air
pressure, electric power, or a control signal to the
actuator. Be sure the actuator cannot suddenly
open or close the valve.

D Use bypass valves or completely shut off the
process to isolate the valve from process pressure.
Relieve process pressure from both sides of the
valve.

D Vent the pneumatic actuator loading pressure
and relieve any actuator spring pre‐compression.

D Use lock‐out procedures to be sure that the
above measures stay in effect while you work on
the equipment.

D The valve packing box might contain process
fluids that are pressurized, even when the valve has
been removed from the pipeline. Process fluids
might spray out under pressure when removing
the packing hardware or packing rings, or when
loosening the packing box pipe plug. Cautiously
remove parts so that fluid escapes slowly and
safely.

D The instrument is capable of supplying full
supply pressure to connected equipment. To avoid
personal injury and equipment damage, caused by
sudden release of process pressure or bursting of
parts, make sure the supply pressure never
exceeds the maximum safe working pressure of
any connected equipment.

D To avoid personal injury or property damage
resulting from the sudden release of process
pressure, use a high‐pressure regulator system
when operating a controller or transmitter from a
high‐pressure source.

D Severe personal injury or property damage
may occur from an uncontrolled process if the
instrument air supply is not clean, dry and oil‐free.
While use and regular maintenance of a filter that
removes particles larger than 40 microns will
suffice in most applications, check with an
Emerson field office and Industry Instrument air
quality standards for use with corrosive gas or if
you are unsure about the proper amount or
method of air filtration or filter maintenance.

D For corrosive media, make sure the tubing and
instrument components that contact the corrosive
media are of suitable non‐corrosive material. The

English

July 2022

use of unsuitable materials might result in
personal injury or property damage due to the
uncontrolled release of the corrosive media.

D If natural gas, or other flammable or hazardous
gas is to be used as the supply pressure medium
and preventive measures are not taken, personal
injury and property damage could result from fire
or explosion of accumulated gas or from contact
with hazardous gas. Preventive measures may
include, but are not limited to, one or more of the
following: remote venting of the unit,
re‐evaluating the hazardous area classification,
ensuring adequate ventilation, and the removal of
any ignition sources.

The instrument or instrument/actuator assembly
does not form a gas‐tight seal, and when the
assembly is in an enclosed area, a remote vent line,
adequate ventilation, and necessary safety
measures should be used. Vent line piping should
comply with local and regional codes and should
be as short as possible with adequate inside
diameter and few bends to reduce case pressure
buildup. However, a remote vent pipe alone
cannot be relied upon to remove all hazardous gas,
and leaks may still occur.

D For instruments with a hollow liquid level
displacer, the displacer might retain process fluid
or pressure. Personal injury or property damage
due to sudden release of pressure, contact with
hazardous fluid, fire, or explosion can be caused by
puncturing, heating, or repairing a displacer that is
retaining process pressure or fluid. This danger
may not be readily apparent when disassembling
the sensor or removing the displacer. Before
disassembling the sensor or removing the
displacer, observe the appropriate warnings
provided in the sensor instruction manual.

D Personal injury or property damage can result
from the discharge of static electricity. Connect a
14 AWG (2.08 mm2) ground strap between the
instrument and earth ground when flammable or
hazardous gases are present. Refer to national and
local codes and standards for grounding
requirements.

D Personal injury or property damage, caused by
fire or explosion from the leakage of flammable or
hazardous gas, can result if a suitable conduit seal
is not installed. For explosion‐proof applications,
install the seal no more than 457 mm (18 inches)
from the instrument when required by the
nameplate. Use the proper cable gland certified to
the required category. Equipment must be
installed per local and national electric codes.

D Check with your process or safety engineer for
any additional measures that must be taken to
protect against process media.

D If installing into an existing application, also
refer to the WARNING in the Maintenance section.
