! NOTE: If mounted properly, the follower arm should be
horizontal when the valve is at 50% stroke and should move
approximately ±30° from horizontal over the full stroke of the
valve. If mounted incorrectly, a stroke calibration error will
occur and the indicator lights will blink a RGGY code indicating
the position sensor has gone out of range on one end of travel.
Reposition the feedback linkage or rotate the position sensor to
correct the error.
5.2 Mounting to Standard
Valtek Rotary Valves
(See Figure 4)
The standard rotary mounting applies to Valtek valve/actuator as-
semblies that do not have mounted volume tanks or handwheels.
The standard mounting uses a linkage directly coupled to the valve
shaft. This linkage has been designed to allow for minimal misalign-
ment between the positioner and the actuator. The tools required for
the following procedure are:
•
5 ⁄
32
" Allen wrench
• ½ " open-end wrench
•
7 ⁄
16
" open-end wrench
• 3 ⁄
8
" socket with extension
• 3 ⁄

1. Fasten the spline lever adapter to the splined lever using two 6 x
½ " self-tapping screws.
2. Slide the take-off arm assembly onto the spline lever adapter
shaft. Insert the screw with star washer through the take-off
arm and add the second star washer and nut. Tighten nut with
socket so arm is lightly snug on the shaft but still able to rotate.
This will be tightened after linkage is correctly oriented.
3. Attach follower arm to positioner feedback shaft using the star
washer and 10-32 nut.
!
NOTE: The arm will point up when feedback shaft is in the free
position.
4. Using four ¼ -20 x ½ " bolts, fasten positioner to universal
bracket using appropriate hole pattern (stamped on bracket).
5. Using a ½ " end wrench and two 5 ⁄
16
-18 x ½ " bolts, attach bracket
to actuator transfer case pad. Leave these bolts slightly loose
until fi nal adjustments are made.
6. Rotate take-off arm so the follower pin will slide into the slot on
the take-off arm. Adjust the bracket position as needed noting
the engagement of the follower pin and the take-off arm slot.
