2 10, 15, 20 Access I 39 Acutators with AS Interface WCAIM2041
Rev. R6 actuators may come with an ISO locating ring used for
optional ISO mounting.
A. Determine mode of operation desired (normally open or normally
closed) of the valve.
B. Determine desired quadrant for bracket attachment and direction
of mounting of actuator (inline or cross-line).
C. Attach mounting bracket to actuator using four (4) cap screws
and lockwashers provided in mounting kit. To avoid any damage
to the Series 39 actuator body, ONLY the proper length screws
supplied with the mounting kit should be used. For
1 /
4
"–2" top
mount style valves, attach bracket such that bracket nameplate
will be to side of valve.
For mounting to 818/828 Series valves, insert ISO locating ring
into groove on bottom of actuator before attaching to bracket.
NOTE: Ring can be permanently held in groove by applying Loctite
to ring before inserting in groove.
D. Attach bracket/actuator assembly to valve as follows:
CAUTION: Ball valves can trap pressurized media in the cavity.
If it is necessary to remove any valve body bolts, stem nuts or
remove valve from the line, and if the valve is or has been in
operation, make sure there is NO pressure to or in the valve
and operate valve one full cycle. However, the valves listed
below do not require the removal of any valve body bolts or
removal of valve from line in order to mount actuator.
1. Rotate valve ball and stem to position necessary to achieve
desired operation. If any valve information is marked on stop
plate or handle, it will be necessary to transfer this
information to the bracket nameplate.

" 82/83 Series valves with high-cycle stem
packing as standard, remove handle nut, lockwasher, handle,
separate stop plate (if any), retaining nut and stop pin(s).
Add the two additional Belleville washers with their larger
diameter sides touching each other. Add the self-locking nut
to the stem and tighten while holding the stem flats with
wrench. Tighten until Belleville washers are flat, the nut will
“bottom”, and then back nut off
1 /

of a turn. The two
additional Belleville washers and the self-locking nut are
included in the mounting kit.
CAUTION: The self-locking stem nut is difficult to tighten,
and must fully flatten Belleville washers before backing off.
For 2" 59, H71, 82/83, and 2 1 /
2
" 45, 82/83 valves, and valves 3"
and larger with square stem, remove handle assembly,
retaining nut, stop and stop screws. Replace with valve stem
spacer or, if valve has graphite stem packing, with two
Belleville washers, and replace retaining nut. NOTE: Belleville
washers are installed with their larger diameter sides touching
each other. Do not use stem spacer when Belleville washers
are used. Using a wrench to prevent stem from turning,
tighten retaining nut until stem packing is fully compressed or
Bellevilles, if used, are fully flattened, then back off nut 1 /
6
turn. Excessive tightening causes higher torque and shorter
seal life.
NOTE: Large valves with V51 high cycle stem packing option
installed, identified by two Belleville washers installed and
handle assembly, stop and stop screws removed, and
818/828 Series valves do not require stem area disassembly.
For 2" and larger 818/828 valves, remove handle
assembly, locking plates and hardware, and stop screw (if
any). Do not remove stop plate or spacer.
For 1 /
2
"–2" 94 valves, remove handle (if any). Do not
remove gland plate or gland bolts.
For 3" and larger 94 and 2" and larger E818/828 valves,
remove handle assembly, stop, and spacer (if any). Do
not remove gland plate or gland bolts.
3. Center coupling on valve stem.
4. Lower mounting bracket/actuator assembly over coupling and
onto valve, making sure that male actuator shaft engages slot
in coupling.
5. Secure bracket to valve using cap screws and lockwashers, or
bolts and nuts provided in mounting kit. Tighten securely. For
1 /
2
"–2" top mount style valves, bracket nameplate will be to
side of valve.
6. Install set screws (if any) in the coupling and tighten securely.
7. Determine if mode of operation is as desired; if not:
a. Double-Acting Actuators – Mount the actuator 90° from
normal mounting, or the actuator can be inverted, yielding
the opposite mode.
b. Spring-Return Actuators – The normal method of
mounting is to have the actuator in line with the pipeline
and the valve and actuator in the “FAIL-CLOSED” position.
For “FAIL-CLOSED” cross-line operation, invert actuator
and cross-line mount actuator to pipeline.
For “FAIL-OPEN” inline operation, invert actuator.
(NOTE: If inline coupling is used, actuator does not need
to be inverted). Rotate the valve ball and stem 90°, so
coupling lines up with actuator shaft. Mount actuator in
line with the pipeline. See Electrical Connection Section
for proper wiring information.
For “FAIL-OPEN” cross-line operation, rotate the valve ball
and stem 90°, so coupling lines up with actuator shaft.
Mount actuator cross-line to pipeline. See Electrical
Connection Section for proper wiring information.
8. Determine position indication. Buttons on position indicator
are set up to show valve closed on inline mounting, i.e.,
pistons together in actuator. If different indication is required:
a. Check which visual indication is required.
b. Check that indicator, when located on actuator shaft, will
show correct indication.
