WARNING
To avoid personal injury or property damage, be aware the travel indicator scale (key 19) retains the locking shaft (key 50)
during normal actuator operation. Removal of the travel indicator scale could allow the locking shaft to fall out in certain
actuator orientations.
Parts Ordering
When corresponding with your
number found on the actuator nameplate.
WARNING
Use only genuine Fisher replacement parts. Components that are not supplied by Emerson Automation Solutions 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.
