STEM ACCESS PORT
Determine if the valve has a stem access port. If there
is
no
stem access port on your valve, skip to the next
step.
If a stem access port
is
used, the cover must be
installed.
Apply anti-seize on studs
22
and install into body
02
.
Install gasket
21
and access plate
27
.
Install nuts
23
, applying anti-seize onto studs
22
and
nuts
23
. Tighten nuts
23
alternately until gasket is
uniformly compressed.
CAUTION!
Torque the access plate bolting (if applicable) per
the specifications included with the
test certificate
for each individual valve serial number.
INSTALL THE FLANGE BUSHING
Insert the flange bushing
16
.
If necessary, tap into place using a hammer and a
brass or aluminum rod or wooden block.

INSTALL GLAND FLANGE
Make sure gland studs
12
are in place. If necessary,
install gland studs
12
, using anti-seize compound.
Install gland flange
07
over stem
05
and gland studs
12
.
Apply anti-seize compound onto gland studs
12
and
gland nuts
15
.
Install gland nuts
15
. Torque all nuts
evenly
per the
specifications included with the
test certificate
for
each individual valve serial number.
CAUTION!
The gland flange
must
be pulled down evenly to
prevent “cocking” or side loading, as this could
cause damage to the packing and prevent the
valve from operating properly.
Watch the gland flange to ensure that it remains
perpendicular
to the stem, and the gap around
the stem remains
concentric
during the tightening
process.
Do not over-tighten nuts. Torque all nuts
evenly
per the specifications included with the
test
certificate
for each individual valve serial number.
If a jacking bolt (or similar tool) was used, it should
now be removed.
If
no
jacking bolt (or similar tool) was used, it may be
necessary to “bottom out” the stem to make contact
between the stem seal bearings and the stem bore
shoulders.
Using an aluminum or brass rod or a wooden block,
“drive” the stem with a hammer until the contact is
made. You will hear a distinct tone when contact is
made.
