8. Use the sequence shown in Figure 2 to install
new packing and associated parts.
9. Place a smooth-edged pipe over the valve
stem, and gently tap each soft packing part into
the packing box bore.
10. Slide the packing follower, upper wiper, and
packing flange (Keys 11, 10, and 3) into
position. Lubricate and install the packing
flange studs (Key 1), and packing flange nuts
(Key 2).
11. For spring-loaded PTFE V-ring packing, tighten
the packing flange nuts (Key 2) until the shoul-
der of the packing follower (Key 11) is approxi-
mately 5/8” from the top of the bonnet.
For other packing arrangements, tighten the
packing flange nuts (Key 2) alternately in
small equal increments. Continue until one of
the nuts reaches the minimum torque value
shown in Table 1. Then tighten the remaining
packing flange nut until the packing flange is
level and at a 90° angle to the valve stem.
12. Mount the actuator on the bonnet (Key 6),
connect the actuator and plug/stem according
to the procedure in the appropriate actuator
instruction manual.
13. Check for leakage around the packing follower
(Key 11) when you put the control valve
assembly into service. Retighten the packing
flange nuts as required.
