Instructions EF35002 - 08/10
Camflex
®
II 35002 Series Control Valves
CAUTION
CAUTION
WARNING
DANGER
Do not exceed pressure listed in Figure 14 for the
actuator used.
G.
Loosen clevis locknut (46).
H.
Reduce air pressure to actuator to 7 psig.
I.
Screw clevis (35) in or out on actuator stem so that the
holes in the clevis (35) and lever (34) are aligned with the
lever and plug in the fully closed position.
J.
Insert clevis pin (7) so indicator dot is visible through front
cover (32) and secure with clevis pin clips (5).
Note: On the size 6 and 7 actuators, without the
adjustable indicator (88), the clevis pin (7) must be
installed so it protrudes toward the front cover (32). If the
indicator dot is damaged, paint may be applied to the
end facing the front cover (32) to make it more visible.
K.
Gradually apply sufficient air pressure to extend clevis
locknut (46) to an accessible position and tighten firmly.
CAUTION
CAUTION
WARNING
DANGER
Do not exceed pressure listed in Figure 14 for the
actuator used.
L.
Relieve air pressure.
M.
If used, replace adjustable indicator (88) to lever (34) with
screws (89).
Note: If required, adjust indicator to front cover
indicator marks.
N.
Replace front cover (32) and rear cover (29) and secure in
place with cover screws (30).
O.
Replace spring barrel boss cover (58) and bottom cover
(11) (Snap fit).
Note: Prior to placing the valve in service, operate the
valve actuator through one complete cycle to ensure
proper functioning.
P.
If desired, set handwheel (53) or optional limit stop (77) to
desired position.
K-1. Air-to-Close
After completing step A through J of Section 11, proceed
as follows:
A.
Manually push lever (34) to the full CLOSED position.
B.
Connect a regulated air supply to the actuator.
C.
Gradually apply the final air pressure corresponding to the
closed position. See value on the serial plate.
D.
With the lever (34) and valve plug in the CLOSED position,
the holes in the clevis (35) and lever (34) should be in line.
Note: If holes are in line proceed to Step H, if not in line,
continue to the next step.
E.
Release air pressure so clevis (35) will separate from lever
(34).
F.
Loosen clevis locknut (46).
G.
Screw clevis (35) in or out so that when the air pressure
corresponding to the closed position mentioned in C above
is applied, clevis holes and lever will be in line.
H.
Insert clevis pin (7) so indicator dot is visible through front
cover (32) and secure with clevis pin clips (5).
Note: On the size 6 and 7 actuators, without the
adjustable indicator (88), the clevis pin (7) must be
installed so it protrudes toward the front cover (32). If
the indicator dot is damaged, paint may be applied to
the end of the clevis pin (7) facing the front cover (32)
to make it more visible.
I.
Tighten clevis locknut (46).
J.
Relieve air pressure to actuator.
K.
If used, replace adjustable indicator (88) to lever (34) with
screws (89).
Note: If required, adjust indicator (88) to front cover
(32) indicator marks with the valve in the closed
position.
L.
Replace front cover (32) and rear cover (29) and secure in
place with cover screws (30).
M.
Replace spring barrel boss cover (58) and bottom cover
(11) (Snap fit).
Note: Prior to placing the valve in service, operate the
valve actuator through one complete cycle to ensure
proper functioning.
N.
If desired, set handwheel (53) or optional limit stop (77) to
desired position.
12. Changing Body Position
CAUTION
CAUTION
WARNING
DANGER
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.
CAUTION
CAUTION
WARNING
DANGER
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.
