Determining Closed Position
1. The valve must be removed from the line to check the position of the ball.
WARNING
The V‐notch ball closes with a shearing, cutting motion. To avoid personal injury, keep hands, tools, and other objects away
from the ball while stroking the valve.
2. Rotate the ball to the closed position.
3. Position the ball in the proper location.
4. The ball is in its closed position when the Vee plane of the ball, (opposite the convex side) is parallel to the liner end
flange face of the valve body. Measure to check. Adjust the actuator linkage or travel stops to position.
CAUTION
To extend operating life of the V‐notch ball, always ensure the V‐notch ball rotates into the top of the valve body to open.
