Actuator Mounting
Use the appropriate actuator instruction manual for mounting the actuator or changing the actuator position. Attach
the actuator mounting bracket to the valve packing box and tighten the mounting bracket fasteners as detailed in
table 5.

1. Fasteners must be lubricated to achieve proper preload
Determining Closed Position
1. To confirm proper actuator adjustment visually check the position of the ball.
2. Adjust the actuator linkage or travel stops as described in the actuator instruction manual so that at the end of
stroke, the valve ball bore diameter in the full open (100%) position is in alignment and centered within the
upstream and downstream valve seal inside diameters. The actuator linkage or travel stops should be adjusted so
that the full closed (0%) valve position is precisely 90 degrees from the visually verified 100% open position.
3. For reference, two parallel lines are machined on the actuator mounting end of the valve drive shaft (key 4). The
lines represent the orientation of the valve ball bore. The ball is in the closed position when the two lines are
perpendicular to the pipeline bore.
Parts Ordering
A serial number is assigned to each valve and stamped on the nameplate. Always refer to the valve serial number when
corresponding with your
regarding spare parts or technical information. When ordering
replacement parts, also specify the part name and desired material.
WARNING
Use only genuine Fisher replacement parts. Components that are not supplied by Emerson should not, under any
circumstances, be used in any Fisher valve, because they may void your warranty, might adversely affect the performance
of the valve, and could cause personal injury and property damage.
