Reassembly of Valve
Stems
Figure 30 - Assembly
NOTE: Perform maintenance on stems and adapter bearings and
o-rings while the stems are removed from the actuator and before
reassembly.
Upper Stem Assembly
1. Apply Bostik® Never-Seez White Food Grade with PTFE or
equivalent to the threads of the upper stem.
2. Screw the upper stem clockwise into the actuator. Hold the
adjusting sleeve stationary with a spanner or allen wrench.
3. Screw the upper stem in until the scribe line (Figure 30, item
A) within the etch mark adjustment zone (item B) aligns with
the bottom of the adjustment sleeve. This is the factory-set
lower seat clean position. See “Seat Cleaning Adjustment” on
page 22 for instructions on modifying the seat clean move-
ment.

WARNING:
Do not screw the upper stem all the way into
the actuator, as internal o-ring damage may result.
Lower Stem Assembly
1. Apply Bostik® Never-Seez White Food Grade with PTFE or
equivalent to the threads of lower stem.
2. If the valve has external flush, slide the spray bushing onto
the inner stem of the lower stem.
3. Screw the lower stem clockwise into the actuator until metal-
to-metal contact stops.
4. Using an open-end wrench and rubber hammer, rap the
lower stem to lock the threads into place within the actuator.
