Valve Installation
WARNING
Always wear protective gloves,
clothing, and eyewear when
performing any installation operations
to avoid personal injury.
Personal injury or equipment damage
caused by sudden release of pressure
or bursting of pressure retaining parts
might result if service conditions
exceed those for which the product
was intended. To avoid injury or
damage, provide a relief valve for over
pressure protection as required by
government or accepted industry
codes and good engineering practices.
Check with your process or safety
engineer for any additional measures
that must be taken to protect against
process media.
If installing into an existing
application, also refer to the WARNING
at the beginning of the Maintenance
section in this instruction manual.

Trim Style Description
Available as an option
This valve is intended for a specific
range of pressures, temperatures and
other application specifications.
Applying different pressure and
temperatures to the valve could result
in parts damage, malfunction of the
control valve or loss of control of the
process. Do not expose this product to
service conditions or variables other
than those for which the product was
intended. If you are not sure what
these conditions are you should
contact your Emerson Process
Management sales office for more
complete specifications. Provide the
product serial number (shown on the
nameplate, figure 2) and all other
pertinent information.
If you move or work on an actuator
installed on a valve with loading
pressure applied, keep your hands and
tools away from the stem travel path to
avoid personal injury. Be especially
