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.
Parts Ordering
Whenever ordering parts for older products, always specify
the serial number of the product and provide all other
pertinent information that you can, such as product size,
part material, age of the product, and general service
conditions. If you have modified the product since it was
originally purchased, include that information with your

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

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

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.
Control Valve Actuators
These safety instructions are limited to pneumatic
actuators which are operating using air or nitrogen (inert
gas). If the application requires use of a flammable or
hazardous gas, you must contact your Emerson sales office
for assistance.
Installation
WARNING
To avoid personal injury and property damage
caused by bursting of parts and to avoid parts
damage, malfunction of control valve, or loss of
control of the process caused by excessive
pressure, do not exceed the maximum pressures
or temperatures for this actuator, as given in the
applicable product literature or on the nameplate.
Use pressure‐limiting or pressure‐relieving devices
to prevent the actuator pressure from exceeding
specified limits. If you cannot determine the 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 actuator, 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 assembly.

sudden release of process pressure or uncontrolled
movement 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 Do not remove the actuator from the valve
while the valve is still pressurized.
D Vent any pneumatic pressure from the
actuator 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 To avoid personal injury due to the sudden
uncontrolled movement of parts, do not loosen
the stem connector cap screws when the stem
connector has spring force applied to it.
D Never apply pressure to a partially assembled
actuator unless all pressure‐retaining parts have
been installed properly.
D Check with your process or safety engineer for
any additional measures that must be taken to
protect against process media.
Regulators
Installation
WARNING
D Personal injury, equipment damage, or leakage
due to escaping gas or bursting of
pressure‐containing parts might result if this
regulator is overpressured or is installed where
service conditions could exceed the limits for
which the regulator was designed, or where
conditions exceed any ratings of the adjacent
piping or piping connections. To avoid such injury
or damage, provide pressure‐relieving or
pressure‐limiting devices (as required by the
appropriate code, regulation, or standard) to
prevent service conditions from exceeding those
limits.
D Additionally, physical damage to a
pilot‐operated regulator could break the pilot off
the main valve, causing personal injury and
property damage due to escaping gas. To avoid
such injury and damage, install the regulator in a
safe location.
