1008 Handwheel Actuator
D100106X012
Fisherr 1008 Handwheel Actuator
The Fisher 1008 manual handwheel actuator is used in
applications that require a throttling type of control
valve that can be manually operated and set. This
actuator can be used on nearly all standard globe-style
or angle-style control valve body assemblies. No
special valve body adaptor is required for use with the
1008 actuator, so that future conversion from manual
to automatic control can be accomplished at
minimum cost.
The 1008 actuator is capable of giving precise manual
throttling control. A travel indicator mounted on the
actuator yoke provides a visual indication of valve plug
position at all times. A dial type valve plug position
indicator is also available as optional equipment.

Features
Easy to Install and Maintain–For sizes 30, 40, and
50, the yoke is attached to the valve body with a
forged steel hammer locknut (figure 1 shows a
typical locknut attachment). For the size 80
(figureNOTAG),theyokeisboltedtothevalve
body. The handwheel mechanism on all sizes is
totally enclosed.
Easy to Operate–Regardless of the valve plug
action, counterclockwise rotation of the handwheel
always opens the valve. In size 40 and larger, two
ball bearings are used in the handwheel assembly to
facilitate rotation. A spring loaded ball detent in the
handwheel prevents it from rotating due to
vibration.

Fisher 1008, Size 80 Actuator
Accurate Valve Plug Positioning–The valve stem
does not revolve, assuring the same seating surface
witheachfullstroke.Also,theyokeconstruction
ensures that the force required to turn the
handwheel cannot be transmitted to the valve
body. Sizes 30, 40, and 50 actuators can be
furnished with a Tejax Model A35 valve position
indicator (figure 2). This indicator enables you to
turn the handwheel to the desired position without
guesswork. The dial on the indicator is divided into
turns and fractions of turns so that you can return to
a predetermined valve setting quickly and easily.
