Introduction
Scope of Manual
This instruction manual includes installation, adjustment, operation, and maintenance information for the Fisher 1077
manual handwheel actuator. Instructions for the control valve is included in a separate manual.
Do not install, operate, or maintain a 1077 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 sales office
Business Partner before proceeding.

Description
The 1077 manual‐only handwheel actuator (figure 1) is used with rotary‐shaft valves such as the Fisher 9500 butterfly
valve, 8532, 8560, and 8580 High Performance Butterfly valves, V150, V200 and V300 Vee‐Ball™ valves, V250 valves,
and CV500 and V500 valves.
In the 1077 actuator, torque is transmitted from the handwheel through the handwheel input shaft to a worm and
drive sleeve gear (sector) with splined bore. The worm and drive sleeve gear multiply the torque and transmit it to a
splined valve shaft or splined stub shaft. The size 10‐KE:6 actuator additionally has a spur gear reduction drive for
increased torque capability.
Specifications
1077 actuator specifications are given in table 1. Some specifications for a given actuator as it comes from the factory
are stamped on a metal nameplate attached to the actuator mounting yoke (key 7, figure 6).

Handwheel Rotation
Direct Acting Construction: Clockwise handwheel
rotation closes the valve (produces clockwise rotation
of valve shaft) as shown in figure 2
Educational Services
Reverse Acting Construction: Clockwise handwheel
rotation closes the valve (produces counterclockwise
rotation of valve shaft) as shown in figure 2
Maximum Output Rotation
0 to 90 degrees
Mounting Positions
J Right‐hand (actuator on right side of valve body
when viewed from the body inlet) or
J Left‐hand (actuator on left side of valve body when
viewed from the body inlet). Position 1 as shown in
figure 3 is standard; however, the actuator may be
mounted in any of the positions shown in figure 3.
Refer to figure 2 to determine the correct actuator
construction

Installation
WARNING
Always wear protective gloves, clothing, and eyewear when performing any installation operations to avoid personal
injury.
If installing into an existing application, also refer to the WARNING at the beginning of the Maintenance section in this
instruction manual.
The 1077 actuator is normally shipped mounted on a control valve body. Follow the procedures in the control valve
body instruction manual for valve installation. Then proceed to the Operation section of this manual.
If the actuator has been shipped separately for installation on a valve body, or if the actuator was removed for
maintenance, mount the actuator by following the instructions presented in this section before installing the valve
body in the pipeline.
Individual part key numbers and part descriptions referenced in this procedure are shown in figure 6 except where
otherwise indicated.
CAUTION
Rotating the valve disk or ball in the wrong direction will damage seals and other internal parts in some valve bodies. If the
drive sleeve gear (key 1A) is not properly positioned, improper disk or ball rotation could result. If there is any doubt as to
whether or not the drive sleeve gear is properly positioned, remove the gearbox cover plate. Use the appropriate view in
figures 3, 4, and 5 to determine that the drive sleeve gear is at the proper end of its rotation.
1. Rotate the valve disk or ball to the closed position. Refer to the separate valve body instruction manual to
determine the closed position. Consult the appropriate valve instruction manual Installation section for valve shaft
orientation marks.
2. Rotate the handwheel (key 5) to move the drive sleeve gear to the position that is to correspond to the closed
position of the valve disk or ball as follows:
For direct acting turn the handwheel so the drive sleeve gear and travel indicator are rotated fully clockwise.
For reverse acting turn the handwheel so the drive sleeve gear and travel indicator are rotated fully counterclockwise.
3. Remove the travel indicator pointer by removing the machine screws. For a size 0‐KE actuator only, remove the
O‐ring seal from the hub of the drive sleeve gear. Locate the four index marks on the drive sleeve gear hub. Also
locate the index mark on the end of the valve shaft.
4. Refer to figures 3, 4, and 5 and locate the correct view for the valve body and mounting position being used. When
the actuator is installed, the valve shaft index mark must be aligned with the proper gear hub index mark.
