Disassembly:
Caution:
Use care when removing the actuator lever, using
a wheel-puller if necessary. If the actuator lever is
forced off the valve shaft the ball could move from
the centered position, damaging the V-Ball, seal and
valve body.
Before disassembly, note the orientation of the actua-
tor in relation to the body and note the orientation of the
lever in relation to the valve body.
1. Remove the actuator cover.
2. Remover the lever.
When the actuator is removed from the valve body,
the ball/shaft assembly may rotate and cause person-
al injury or damage to equipment. Prevent rotation
by turning the V-Ball to a stable position in the body.
3. Detach the valve from the line. It is necessary
for the removed valve to be positioned
so that the seal ring or flow ring is pointed
upward.
4. Unscrew the cap screws (key 19) that hold the
seal protector ring in place (key 22).
5. Carefully remove the ring from the body ensur-
ing that the surface of the ball is not nicked or
scraped
6. Remove the O-ring (key 24).

constructions.
8. Lift the shim seals (key 20).
9. Clean all parts and inspect for damage.
10. Remove packing flange nuts (key 3) and lift the
packing flange and follower (key 15) from the
packing box.
11. With a formed wire hook, remove the packing
rings.
12. Clean the packing box and all metal parts com-
plete all required maintenance.
13. Locate and remove the groove pin (key 10).
14. Unscrew the guidepost retaining nuts (key 14) or
the retainer, depending on valve body size.

18 Find the groove pin hole, noting that the V-Ball
has a raised flat surface on one side. To remove
the groove pin, place a punch on the side of the
ball opposite the raised flat surface and
drive the out pin (Key 10). See Figure 12.
19. Slip the drive shaft through the body out the
guidepost end. Remove the thrust washer.
20. Carefully remove the ball from the body ensuring
that the surface of the ball is not nicked
or scraped.
