Key numbers in this procedure are shown in figures 6, 14, and 15, unless otherwise indicated.
1. For
DN 80 and 100 (NPS 3 and 4)
, seal protector ring (key 3) and HD seal (key 5) should be removed first, refers to
procedure of Removing HD Seal on page 12. For
DN 150, 200, and 250 (NPS 6, 8, and 10)
, HD seal will be removed
after ball (key 2) is removed in this procedure.
2. A taper key (key 4) is used to connect the ball and drive shaft.
3. Carefully rotate the ball to the open position after the actuator is disconnected. Make sure the ball will not rotate
(see warning above). Provide support for the ball during the following disassembly.
4. Working from the small end of the groove pin (key 7), use a pin punch to drive the groove pin out of the ball ear and
follower shaft.
For tack welded taper keys,
driving the taper key out of the ball ear will shear the tack welding.
5. Locate the small end of the taper key (key 4). Using a pin punch on the smaller end of the taper key, drive it out of
the ball (key 2) and drive shaft (key 6). Note: driving the taper key in the wrong direction will tighten it.
6. Pull the drive shaft (key 6) out of the actuator side of the valve body.
CAUTION
Exercise care to avoid damaging components in the following procedure.
7. The ball will be free to move when both shafts are removed. Make sure the sealing surface of the ball is not
damaged while removing the follower shaft.
8. Use a piece of continuous threaded rod as a removal rod when moving the follower shaft (key 9) into the center of
the ball. Refer to table 5 for a description of the size threaded rod needed. The length of the rod should allow easy
working room from the valve body.

9. Carefully remove the follower shaft.
10. For
DN 80 and 100 (NPS 3 and 4)
, the ball (key 2) should be removed from the inlet opening of the valve body. Lift
the ball to clear the bearings (key 10). Engage the ball drive shaft side ear with the body as shown in figure 8 and
carefully lift the ball by the follower side ear to remove.
For
DN 150, 200, and 250 (NPS 6, 8, and 10)
, the ball (key 2) should be removed from the outlet opening of the
valve body. Lift the ball to clear the bearings (key 10). Engage the ball drive shaft side ear with the body as shown in
figure 9 and carefully lift the ball by the follower side ear to remove.
11. The bearings are not pressed in, so they can be removed with minimal force. Be careful not to damage the
machined surfaces of the bearing bore if prying is required.
For HD seal removal, follow the steps outlined under Removing HD Seal of this manual.
