Assembly Continued,
9. Ensure that the warning nameplate (Key 27) is in
place and install the diaphragm (Key 25) and
the upper diaphragm casing (Key 26).
10. Install the cap screws and hex nuts (Keys 45
and 44). Tighten cap screws evenly
using a crisscross pattern to compress
the spring, and then secure the upper
diaphragm casing.
11. Refer to the appropriate valve body instruction
manual for lever/valve shaft orientation marks,
and slide the lever (Key 33) into place. See
Figure 4 for correct lever operating
clearance. Clamp with the cap screw (Key 10).
12. Rotate the lever (Key 33) until it aligns with the
rod end bearing (Key 13). This connection can
be assisted by stroking the actuator off
its up travel stop using a regulated air source.
13. Apply a thread-locking compound to the threads
of the cap screw (Key 12).
14. Connect the lever (Key 33) and the rod end
bearing (Key 13) with the cap screw and
hex nuts (Keys 12 and 31). Tighten the
cap screw to the torque as recommended in
Table 1).
15. If a valve positioner is being used with the as-
sembly, consult the appropriate manual
for positioner installation.
16. Coat the bearing surfaces of the hub (Key 30)
and the cover (Key 41) with a suitable lubricant.
Install the bushing (Key 40) and hub into the
cover and secure with the retaining ring
(Key 36).
17. Install the travel indicator scale (Key 39) and
secure with self-tapping screws (Key 37).
18. Make note of the valve position and direction of
rotation and position the travel indicator (Key 38)
accordingly.
19. Replace the cover (Key 41) and secure with cap
screws and washers (Keys 8 and 9). If
the holes in the cover and housing (Key 17) do
not align, use a regulated air source to
move the actuator slightly off its up travel stop.
If this does not result in proper alignment
temporarily loosen the cap screws
(Key 32) and shift the housing slightly.
Do not stroke the actuator while the cover is off.
20. Refer to the Adjustment section of this manual
for correct actuator turnbuckle adjustment.
Changing Actuator Mounting
Generally the actuator is positioned vertically in a
horizontal pipeline, however there are four possible
mounting styles and for possible positions for each style.
Refer to Figures 2 and 3.
Correct lever/valve shaft positioning is important in
ensuring proper valve action. Refer to the appropriate
valve body instruction manual.
Warning: The sudden release of process fluid can
cause personal injury or property damage. Prior to
starting adjustment procedures:
•
Isolate the valve from the process,
• Release the process pressure, and
• Vent the actuator loading pressure.
Style A is right-hand mounted and Style D is left-hand
mounted. In all other ways Styles A and D are identical.
Style B is right-hand mounted, while Style C is left-hand
mounted. In all other ways Styles B and C are identical.
Refer to the following procedure to convert from Styles A
and D to Styles B and C or vice versa, or to change the
mounting position. Key numbers refer to Figures 6 & 7.
1. Remove the cover (Key 41) by unscrewing and
removing the cap screws and washers (Keys 8
and 9).
2. Unscrew cap screw (Key 12) and loosen cap
screw (Key 10).
Warning: Do not use a hammer to drive the lever off
the drive shaft. This could cause damage to internal
valve parts. On some valves, driving the lever could
move the valve ball and bearings away from the cen-
tered position, resulting in damage to valve parts as
the valve is operated.
If using a tool to remove the lever is necessary, use a
wheel puller. Tapping the wheel puller screw lightly
to loosen the lever is permissible, but excessive
force could also result in damage to valve parts and
disruption of the centered position of the valve disk
and bearings.
