5. Installing the Drive Shaft:
CAUTION
The drive shaft must be used with the correct Vee‐Ball. Refer to the tag (see figure 13) attached to the Vee‐Ball and to the
drive shaft.
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.
