6. For spring-loaded PTFE V-ring packing,
tighten the packing flange nuts until the shoulder on
the packing follower (key 13, figure 4) contacts the
bonnet.
For graphite packing, tighten the packing flange
nuts to the maximum recommended torque shown in
table 4. Then, loosen the packing flange nuts, and
retighten them to the recommended minimum torque
shown in table 4.
For other packing types, tighten the packing flange
nuts alternately in small equal increments until one
of the nuts reaches the minimum recommended
torque shown in table 4. Then, tighten the remaining
flange nuts until the packing flange is level and at a
90-degree angle to the valve stem.
Note
If the valve has ENVIRO-SEAL
live-loaded packing installed (figure 9,
10, or 11), see the Fisher instruction
manual entitled ENVIRO-SEAL Packing
System for Sliding-Stem Valves for
packing instructions.
If the valve has HIGH-SEAL
Heavy-Duty live-loaded packing
installed (figure 8), see the Fisher
instruction manual entitled HIGH-SEAL
Live-Loaded Packing System for
packing instructions.
Packing Lubrication
WARNING
To avoid personal injury or property
damage resulting from fire or
explosion, do not lubricate packing
used in oxygen service or in
processes with temperatures over
260_C (500_F).
Packing used in oxygen service or in processes with
temperatures over 260_C (500_F) should not be
lubricated. If a lubricator or lubricator/isolating valve
(see figure 7) is required for the packing, install the
lubricator or lubricator/isolating valve into the
threaded hole in the side of the bonnet (see
figure 7). Use a good quality silicon-base lubricant.
To operate the lubricator, simply turn the cap screw
clockwise to force the lubricant into the packing box.
The lubricator/isolating valve operates the same way
except the isolating valve must first be opened and
then closed after lubrication is completed.

Parts Ordering
Each body-bonnet assembly is assigned a serial
number which can be found on the valve body. This
same number also appears on the actuator
nameplate when the valve is shipped from the
factory as part of a control valve assembly. Refer to
the serial number when contacting your Emerson
Process Management sales office for technical
assistance. When ordering replacement parts, refer
to the serial number and to the eleven-character part
number for each part required from the following
parts kit or parts list information.
WARNING
Use only genuine Fisher replacement
parts. Components that are not
supplied by Emerson Process
Management should not, under any
circumstances, be used in any Fisher
valve, because they will void your
warranty, might adversely affect the
performance of the valve, and might
jeopardize worker and workplace
safety.
Note
Neither Emerson, Emerson Process
Management, Fisher, nor any of their
affiliated entities assumes
responsibility for the selection, use
and maintenance of any product.
Responsibility for the selection, use,
and maintenance of any product
