11. Actuator Stem Adjustment
(Refer to Figures 16 and 17)
CAUTION
CAUTION
WARNING
DANGER
The following procedures must be adhered to in order to ensure
correct valve operation. Failure to do so could result in valve
damage and equipment malfunction.
Correct actuator stem adjustment is imperative for proper valve
functioning. With the actuator assembled to the valve in the
desired location and orientation proceed as follows:
Note: If any of the following steps were completed during
maintenance or reorientation of actuator to valve, proceed to
the next step.
A.
Remove front cover (32) and rear cover (29) by removing the
two-cover screws (30).
B.
Back off handwheel (53) so it does not interfere with the
operation of the lever (34).
C.
If applicable, back off optional limit stop (77) so it will not
interfere with the operation of the lever (34).
D.
Apply air pressure to the actuator and move lever (34) to an
intermediate position.
CAUTION
CAUTION
WARNING
DANGER
Do not exceed pressure listed in Figure 14 for the actuator
used. Do not use handwheel (53) to move lever (34).
E.
Remove adjustable indicator (88) by removing the two
screws (89).
F.
Remove clevis pin clip (5), remove clevis pin (7).
G.
Relieve air pressure to the actuator to allow the clevis (35) and
lever (34) to separate.
Note: If the unit is air-to-open, separate clevis (35) and lever
(34) then loosen clevis locknut (46) and remove clevis.
H.
Insert clevis pin (7) back in lever (34).
I.
Manually push the lever (34) so the valve is in the closed
position.
J.
Temporarily replace front cover (32) and check the location of
the clevis pin (7) in relation to the closed position indicator mark
on front cover (32).
CAUTION
CAUTION
WARNING
DANGER
The relationship must be as shown in Figure 18. If it is not,
the yoke must be separated from the body and the lever
(34) repositioned on the shaft. Refer to appropriate section.
Failure to comply could result in the valve short stroking or
over stroking and could damage the valve.
Note: If the unit is air-to-open, replace clevis locknut (46)
and clevis (35).
K.
Proceed to one of the following sections for final adjustment.
Air-to-Open, Section (K-1), Air-to-Close Section (K-2).
K-1. Air-to-Open
After completing step A through J of Section 11, proceed as
follows:
A.
Scribe a line on the clevis (35) in line with the inside of the
yoke.
B.
Connect a regulated air supply directly to the actuator and
gradually apply 8 psig (.55 barg) for size 9 actuators and 7
psig (.48 barg) for the others.
C.
The clevis should move approximately 1/4".
D.
With the lever and valve plug in the fully CLOSED position,
the holes in the clevis (35) and lever (34) should be in line.
Note: If holes are in line proceed to Step J. If not in line,
continue to next step.
E.
Move lever (34) to full open position.
F.
Gradually apply sufficient air pressure to extend clevis
locknut (46) to an accessible position.
