13. Changing Actuator Action
Before any change in flow direction or actuator mode
is made, the valve and actuator must be resized using
current process conditions. Any change in the flow
direction or actuator mode must be accomplished
as outlined in this instruction, otherwise equipment
malfunction could result.
A.
Remove front cover (32) and rear cover (29) by removing
the two cover screws (30).
B.
Remove spring barrel boss cover (58) (Snap fit).
C.
Remove bottom cover (11) (Snap fit).
D.
Using a manual loading panel, apply sufficient air pressure
to the actuator to move the lever (34) to an intermediate
position.
Do not exceed pressure listed in Figure 14 for actua-
tor used. Do not use handwheel to move lever.
E.
Remove clevis pin clips (5) and remove clevis pin (7).
F.
Position lever so it does not contact handwheel power-screw
assembly.
G.
Remove Truarc ring (50) and washer (51) from handwheel
powerscrew assembly.
H.
Unscrew and remove handwheel powerscrew assembly
from yoke (33).

12. Changing Body Position
Before any change in flow direction or actuator mode
is made, the valve and actuator must be resized using
current process conditions. Any change in the flow
direction or actuator mode must be accomplished
as outlined in this instruction, otherwise equipment
malfunction could result.
Changing service requirements or service conditions may
require a change in flow direction through the Camflex II valve.
Figure 19 illustrates the various positions and flow directions in
which the valve may be placed to accommodate requirements.
Changing the body position and flow direction could
also require relocating the actuator. Ensure that the
actuator location and action are in accordance with
the recommended positions and modes illustrated in
Figure 19. Illustrations are shown looking at the body
through the bonnet with the actuator in front of the
valve. The plug shaft is always rotated in a clockwise
direction by the actuator to open the valve.
To change body position proceed as follows:
A.
Refer to Figure 19 and determine which is the desired
valve position, flow direction and which actuator position is
required.
B.
Proceed to the appropriate section of this instruction for the
required disassembly and assembly procedures.
