1) Remove the lock nut, spring, and knob.
2) Undo the packing nut. When the packing nut is free
of the threads of the emergency valve body, back out
the stem until it is free of the emergency valve body.
3) Remove the packing nut, packing, and washer from
the stem.
7.6.2 Cleaning and Lubricating
1) Clean all the metal parts in a soap and water
solution, followed by cleaning with a 50/50 dilute
solution of white vinegar/water. Rinse with fresh
water. Clean all parts. See the cleaning instructions
in Section 6.3.2.
2) Inspect the packing and washer for wear and re
-
place if necessary. Normally the packing will last a
very long time and does not require replacement as
long as the valve operates smoothly and does not leak.
To replace the packing place the packing nut in a vise
and carefully work the packing out with a small screw
driver, taking care not to damage the threads of the
packing nut. Replace the washer.
3) Inspect the stem seat for unevenness or wear and re
-
place if necessary. It must also be replaced if the stem
is bent. Damage will include damaged threads, and/
or rounded flats that engage the control knob. Also
inspect the shaft to ensure the conical seat surface is
smooth and free of corrosion or damage.
4) Check the seat in the emergency valve body for
wear or unevenness, galling and corrosion. To clean
up the seat surface use a pencil eraser to buff the
surface. Inspect all threaded surfaces for damage.
Remove the valve stem.
Remove the lock nut, spring and knob.
Undo the packing nut.
Inspect the packing and washer.
