Note
To obtain proper shutoff, the closed position of the A41/8560 valves must be set with the disc parallel to the retaining ring. Don't
use the disc stop to set the actuator travel stops.
3. Adjust the actuator travel stop to limit the open and closed positions of the valve disc. (If necessary, refer to the
actuator instruction manual for more information about adjustments.) Do not use the disc stop as a actuator travel
stop as discussed in the
Caution
above.
4. For actuators with adjustable turnbuckles, adjust the turnbuckle to bring the disc to the fully closed position at the
end of the actuator stroke. If necessary, refer to the appropriate actuator instruction manual for assistance.
5. If using a manual handwheel or handlever actuator, refer to the appropriate actuator instruction manual for
mounting positions and adjustments.
6. To determine the fully closed disc position (zero degrees of disc rotation), measure the distances between the
positions on the disc face as shown in figure 10. Use the actuator to rotate the disc while re‐checking the two
measurements. Repeat adjustment until the two measurements are equal.
