Actuator Mounting

Use the appropriate actuator instruction manual and figure 10 of this instruction manual when changing actuator
styles and positions. The actuator may be either right‐ or left‐hand mounted. Figure 10 shows the correct lever/shaft
orientation for both left‐hand mounting and right‐hand mounting configurations.

Travel Adjustment

Actuator travel adjustment can be performed with the valve either in or out of the pipeline. Key numbers referenced in
the following procedures are shown in figure 11 for single seal and flow ring constructions and in figure 12 for dual seal
constructions.
For valve assemblies in the pipeline:
1. Rotate the ball (key 2) to either the open or closed position as indicated by the travel indicator scale (key 37) on the
outboard end of the valve.
2. Adjust the actuator as described in the appropriate actuator instruction manual until the arrow stamped on the end
of the follower shaft (key 7) is fully aligned with the open or closed position on he travel indicator scale.
For valve assemblies out of the pipeline, proceed as follows:
1. Rotate the ball to the fully open position. The fully open position is achieved when the inside surface of the ball bore
(key 2) is completely square with the line flange gasket surface of the seal protector ring (key 14) or flow ring (key
14).
2. Adjust the actuator as described in the appropriate actuator instruction manual until the inside surface of the ball
bore is at right angles to the line flange gasket surface of the seal protector ring or flow ring.
3. Adjust the travel indicator scale (key 37) until the arrow stamped on the end of the follower shaft (key 7) is fully
aligned with the open position.
