9. Thoroughly clean surfaces of all parts that are to be re‐used or obtain replacement parts.
Assembly
1. Inspect all sealing surfaces to ensure they are in good condition and without scratches or wear.
2. Install the replacement bearings (key 10) by hand. The bearing flanged end should touch the valve body.
3. Installing the Vee‐Ball: Ensure the ball part number matches up with the appropriate seal type as shown in the key 2
ball table in the parts list section of this instruction manual.
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.
Note
For ease of assembly, the follower shaft (key 9) should be inserted into the ball before installing the ball in the following
applications:
D
NPS 3 valve without ball/attenuator
D
NPS 4 through 12 valves with ball/attenuator.
Carefully install the ball into the valve body cavity.
D For Vee‐Ball with attenuator (NPS 4 through 12 valves), carefully install the ball into the valve body cavity. For NPS 4
valves, install the ball/attenuator through the inlet of the valve. For NPS 6, 8, 10, and 12 valves, install the
ball/attenuator through the outlet of the valve. Taking hold of the follower shaft ear on the ball/attenuator, you
must position the scalloped edge of the attenuator against the valve bore opening and then carefully pivot, or roll,
the ball/attenuator into the valve body (see figure 18).
After you have installed the ball (key 2) into the valve body assembly, firmly support the ball while installing the shafts.
4. Installing the follower shaft (key 9):
D For NPS 3 valves: 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 NPS 4 and larger valves: Insert the follower shaft (key 9) through the ball, and into the valve body bearing (key
10).
D For NPS 4 through 12 valves with ball/attenuator: The follower shaft (key 9) should already have been inserted into
the ball/attenuator before the ball was put into the valve body. Insert the follower shaft (key 9) into the valve body
bearing (key 10).
Then for all sizes, 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.
