Installing the Vee‐Ball:
Lubrication will assist with break-in of the HD metal seals and with assembly. It is required
that both the ball surface and seal be lubricated with dry film lubricant or equivalent moly disulfide.
WARNING
The ball might be damaged if it is allowed to fall into the valve body. To avoid personal injury or damage to the sealing
surfaces, support the ball to prevent it from falling into or out of the valve body cavity.
Place the valve body on a table or bench.
D
For
DN 80 and 100 (NPS 3 and 4)
, the ball (key 2) should be installed from the inlet opening of the valve body.
The follower shaft (key 9) should be inserted into the ball before the ball is installed. Engage the ball drive shaft
side ear with the body as shown in figure 8 then lower the follower side ball ear into the body and position the
ball between the bearings.
D
For
DN 150, 200, and 250 (NPS 6, 8, and 10),
the ball (key 2) should be installed from the outlet opening of the
valve body. Engage the ball drive shaft side ear with the body as shown in figure 9 then lower the follower side
ball ear into the body and position the ball between the bearings.
4. Installing the Follower Shaft (key 9):
D
For
DN 80 and 100 (NPS 3 and 4),
the follower shaft (key 9) should already have been inserted into the ball before
the ball was put into the valve body. Insert the follower shaft (key 9) into the valve body bearing (key 10).
D
For
DN 150, 200, and 250 (NPS 6, 8, and 10),
with the ball rotated open and not in contact with the HD seal,
insert the follower shaft (key 9) through the ball, and into the valve body bearing (key 10).
5. Align the hole in the follower shaft with the holes in the ball. Insert the small end of the groove pin (key 7) into the
hole in the ball and into the follower shaft. The pin will hold the parts in place while the drive shaft (key 6) is being
installed.
6. Installing the Drive Shaft (key 6):
CAUTION
Failure to use the correct Vee‐Ball/shaft combination may result in the ball not being in the position indicated by the slash
mark on the end of the shaft. If the ball is not properly aligned with the slash mark, the valve will not function correctly and
seal damage may result.
Make sure the drive shaft is free of oil or grease, otherwise the taper pin or taper key will not seat properly. Failure to
properly set the taper pin or taper key could result in it coming loose while in service. Loosening of the taper key in service
could result in improper valve function and equipment damage.
