figure (Figure 10 to open, Figure 11 to close)�
To obtain proper alignment, the lever must be
oriented on the shaft so that the slot in the end
of the shaft and arrows or indicator lines are
aligned as shown; with the ball in the closed
position, the distance between the top of the
bracket and the top of the pivot pin must be as
shown�
F. Flip lever (32) and lever arm (64) and replace on shaft
90 away from original position. Replace indicator arm
(35). Slide bracket back onto bracket mounting studs
(26), replace washers (18) and nuts (24) and tighten. Slide
packing flange (23) back over packing flange studs (25)
and replace packing flange stud nuts (24) and tighten.
G. Replace actuator on bracket in correct mounting
position for air action. Replace actuator stud nuts (75)
and washers (76). Position lever (32) and lever arm
(64) so that rod end bearing (94) lines up in lever (32).
Tighten lever cap screw (33).
H. Place ball plug (2) in closed position. If actuator action
is air to open, loosen rod end bearing nut (93) and
adjust position of rod end bearing (94) so that holes in
lever (32) and rod end bearing (94) line up. Insert pivot
pin (39) and replace retaining rings (40).
I. If action is air to close, place ball plug (2) in closed
position and pneumatically stroke actuator fully.
Do not exceed maximum air supply pressure�
J. For both air to open and air to close action, stroke valve
fully to ensure proper closure of ball plug and operation
of valve. Tighten rod end bearing locknut (93).
When stroking valve keep hands and
equipment clear of ball plug and seal ring
to avoid injury or damage to personnel or
equipment�
K. Replace handwheel bracket (62), cap screws (70)
and lockwashers (71) on opposite side of actuator
bracket from where originally found. Insert handwheel
assembly in bracket and replace clevis pin (66),
retaining rings (63), lever arm bearing (65) and pivot
pins (72). Replace shaft cover (42) and screw (43).
L. Set and lock indicator (35) to indicate plug position.
2�5�2 Model 33, size AC only� For sizes B & C refer
to section 2�5�1 above�
A. If the valve is equipped with a handwheel disengage
the handwheel and remove retaining clip (54-7) and
washer (54-4). Remove handwheel assembly (54) from
housing (31) by rotating counter-clockwise.
B. Remove pivot pin retaining clips (40), pivot pin (39).
Remove actuator hex nuts (75) and washers (76).
Remove actuator.
C. Remove cover (48) from opposite side of bracket (31)
and install on side actuator was just removed from.
Note: Cover (48) is attached to yoke with contact
adhesive that is pre-applied. If a new cover is not
available, it can be re-installed by applying contact
adhesive to the cover and bracket following the
instructions for the specific adhesive used.
D. Install actuator on opposite side of yoke than it was
removed from. Attach using washers (76) and hex nuts
(75).
Before proceeding determine valve action (air
to open/air to close)�
E. Rotate ball plug (2) to closed position. Verify closed
position travel stop (102) contacts the pad on lever (32).
Adjust as necessary. Tighten locknut (101).
Ensure rotation of AC actuator does not
exceed 90deg� Damage to actuator rod may
result�
F. Rotate ball plug (2) to open position. Verify open
position travel stop contacts pad on lever (32). Adjust as
necessary. Tighten locknut (101).
G. If actuator action is air to open, rotate ball plug (2) to
open position. Pneumatically stroke actuator to open
position. Loosen rod end bearing locknut (93) and
adjust position of rod end bearing (94) so that holes in
lever (32) and rod end bearing (94) line up. Insert pivot
pin (39) and retaining rings (40).
When stroking valve keep hands and
equipment clear of ball plug and seal ring
to avoid injury or damage to personnel and
equipment�
H. If action is air to close place ball plug (2) in closed
position. The pad on lever should contact the closed
position travel stop (102). If it does not, repeat
