Introduction
Scope of Manual
This instruction manual presents principle of
operation, installation, maintenance, and parts list for
the Fisher 1008 handwheel actuator (figure 1). Refer
to separate instruction manuals for information about
other equipment and accessories used with these
actuators.
Do not install, operate, or maintain a 1008
handwheel actuator without being fully trained and
qualified in valve, actuator, and accessory
installation, operation, and maintenance. To avoid
personal injury or property damage, it is important to
carefully read, understand, and follow all the
contents of this manual, including all safety cautions
and warnings. If you have any questions about these
instructions, contact your Emerson Process
Management sales office before proceeding.
Description
The 1008 is a handwheel actuator for processes
requiring a throttling valve that can be manually

operated and set. The 1008 handwheel actuator is
available in sizes 30, 40, 50, 80, and 100, and can
be mounted on easy-e
t
valves.
The 1008 handwheel actuator converts rotary motion
of the handwheel to linear motion of the valve plug
stem. Because the stem does not revolve, the valve
plug contacts the same seating surface with each
stroke. Sizes 40, 50, 80, and 100 include two thrust
bearings to make rotation easier.
Turn the handwheel counterclockwise to open the
valve regardless of valve plug action. All sizes of the
1008 handwheel actuator except size 100 are
reversible following the Reversing Handwheel
procedures in this instruction manual.
