1. Disassemble the valve as directed earlier. Remove the locknuts (key 27) and indicator disk (key 58), and turn the
plug stem (key 5) out through the packing box. Remove the packing follower (key 10). Push out the old packing
(key 14) by working from the underside of the bonnet (key 8).
2. Standard Spring Loaded PTFE V-Ring Packing (figures 2 and 7): Carefully insert each piece in exact order shown in
figure 7. Turn the packing follower (key 10) until it shoulders on the bonnet (key 8). This will compress the packing
spring (key 6) to enable constant stem sealing throughout packing life.
3. Molded Graphite Ribbon Packing (figure 8): Carefully insert each piece in exact order shown in figure 8. Hand
tighten the packing follower (key 10). Use a wrench to increase tightness by turning the follower an additional 60
degrees.
4. ENVIRO-SEAL ™ Packing (figure 9): Carefully insert each piece in exact order as shown in figure 9. Tighten the
packing follower (key 10) until the Belleville springs are compressed. This will be signaled by a significant increase in
resistance. Back off the follower 1/8 to 1/4 turn. A gap of approximately 1.5 mm (1/16 inch) between the packing
follower and the bonnet will ensure the packing is seated properly.
Actuator and Valve Body Reassembly
1. Insert a new valve body gasket (key 49) and install the bonnet assembly (key 8).
2. Place the actuator yoke over the stem (key 5). While tilting the actuator back, drop the yoke drive nut (key 9) over
the stem (key 5). Run the locknuts (key 27), and the travel indicator (key 58), down as far as possible and counter
tighten the locknuts (key 27) to lock.
3. Carefully position the actuator over the stem (key 5), lift the plug stem (key 5) and turn the plug stem (key 5) into
the actuator stem as far as it will go before adjusting the bench range.
See the following instruction manual (Baumann Actuator Instructions, D103352X012 ) for reassembly and bench
range adjustment.
CAUTION
When assembling or disassembling the valve, do not turn the valve stem while the plug is in contact with the valve seat.
This can damage the seating surface very quickly.
WARNING
To avoid personal injury or equipment damage due to possible sudden shifting or falling of the valve assembly, do not lift
the valve assembly by the handwheel.
Parts Ordering
When corresponding with your Emerson sales office about this equipment, always mention the valve serial number.
When ordering replacement parts, also specify the key number, part name, and desired material using the following
parts tables.
WARNING
Use only genuine Fisher ™ replacement parts. Components that are not supplied by Emerson should not, under any
circumstances, be used in any Fisher valve, because they may void your warranty, might adversely affect the performance
of the valve, and could cause personal injury and property damage.
