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.
Donotinstall,operate,ormaintaina1077 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 1077 manual-only handwheel actuator (figure 1) is used with rotary-shaft valves such as the Fisher 9500 butterfly
valve, 8532, 8560, and 8580 eccentric disc valves, V150, V200 and V300 Vee-Ball™ valves, V250 valves, and CV500
and V500 eccentric plug 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).

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 and 7 except
where otherwise indicated.
CAUTION
Rotating the valve disc 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 disc 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 disc 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 disc 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-ringsealfromthehubofthedrivesleevegear.Locatethefourindexmarksonthedrivesleevegearhub.Also
locate the index mark on the end of the valve shaft or stub shaft (key 13, figure 7).
4. Proceed as appropriate:
a. For valves with splined shafts, 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.
b. For valves with keyed shafts, compare the position of the stub shaft keyway with the position of the connector
(key 11, figure 7) keyway. Align the stub shaft index mark withtheappropriatedrivesleevegearhubindexmark
such that the connector keyway will be in line with the valve shaft keyway.

Adjustment
Perform the following steps to adjust the travel stops and the travel indicator pointer. Individual part key numbers and
part descriptions referenced in this procedure are shown in figure 6 except where otherwise indicated.
Travel stops (key 10) consist of two set screws and two hex nuts. For 90-degree valve disc or ball rotation, both set
screws are of equal length. For 60-degree disc or ball rotation, one set screw is longer than the other. To change from
90-degree to 60-degree disc or ball rotation, one set screw must be replaced with a longer one as explained below.
Note
Sizes 2-KE, 7-KE, 9-KE & 10-KE:6 use the same actuator for both 0-60 degrees and 0-90 degrees, with the replacement of the
appropriate set screw. Sizes 0-KE & 6-KE require a different actuator when changing from 90-degree to 60-degree disc or ball
rotation.
For Direct acting (except for 0-KE & 6-KE), replace the set screw that limits counterclockwise drive sleeve gear and
travel indicator rotation.

For Reverse acting (except for 0-KE & 6-KE), replace the set screw that limits clockwise drive sleeve gear and travel
indicator rotation.
Note
A 60-degree set screw used as an opening stop can limit valve ball or disc opening to any angle between 60 and 90 degrees.
Alternately, it may be used as a closing stop to limit valve closing to any angle between 0 and 30 degrees. One or two 60-degree
set screws may be used to extend the range of the valve opening stop, the valve closing stop, or both
1. If the valve body is in the line, remove it by following the instructions in the separate valve body instruction manual.
2. Loosen the hex nuts and back out both set screws.
3. Rotate the handwheel (key 5) to move the valve disc or ball to the fully closed position. Refer to the separate valve
body instruction manual for instructions to determine the fully closed position of the disc or ball.
4. With the valve disc or ball closed, rotate the set screw that is to limit valve closing until this set screw just hits the
drive sleeve gear. Lock the set screw with the hex nut.
5. Rotate the handwheel until the disc is at the desired maximum rotation as indicated by the pointer tip on the travel
indicator dial. Rotate the remaining travel stop set screw until it just hits the drive sleeve gear. Lock the set screw
with the hex nut.
6. Installthevalvebodyandactuatorinthepipelinebyfollowingtheinstructionsintheseparatevalvebody
instruction manual; then proceed to the Operation section.
Operation
Individual part key numbers and part descriptions referenced in this procedure are shown in figure 6 except where
otherwise indicated.
After the travel stops (key 10) and travel indicator pointer have been adjusted and the control valve assembly installed,
the actuator is ready for operation. The handwheel rotation direction required to open the valve is indicated on the
face of the handwheel (key 5).
CAUTION
To avoid damage t o the actuator, the valve shaft splines, and internal valve parts, do not exceed the maximum allowable
torques listed in table 2 or any other torque limitation of internal valve parts. Also, do not use wrenches or other devices on
the handwheel or handwheel shaft to increase operating force.
If the force required to rotate the handwheel will exceed the wheel-rim force listed in table 2, check for the following
conditions:
D Insufficient lubrication,
D Seized actuator parts,
D Excessive pressure drop across the valve body, or
9
Page 10
1077 Actuator
July 2012
Instruction Manual
D101296X012
D Obstruction to the valve body disc or ball rotation.
Instructions are given in the Maintenance section for lubrication of actuator parts. Refer to the separate valve body
instruction manual if valve body maintenance is required.
If the actuator does not seem to control the process fluid, worm or drive sleeve gear teeth may be broken, the pin
(key 6) may be sheared, or internal valve body parts may be broken. Refer to the separate valve body instruction
manual if valve body maintenance is required.
Maintenance
WARNING
Avoid personalinjury or property damage from sudden release of process pressure or bursting of parts. Before performing
any maintenance operations:
D Do not remove the actuator from the valve while the valve is still pressurized.
D Always wear protective gloves, clothing, and eyewear when performing any maintenance operations to avoid personal
injury.
D Be sure the actuator cannot suddenly open or close the valve.
D Use bypass valves or completely shut off the process to isolate the valve from process pressure. Relieve process pressure
from both sides of the valve. Drain the process media from both sides of the valve.
D Vent the pneumatic actuator loading pressure and relieve any actuator spring precompression.
D Use lockout procedures to be sure that the above measures stay in effect while you work on the equipment.
D The valve packing box may contain process fluids that are pressurized, even when the valve has been removed from the
pipeline. Process fluids may spray out under pressure when removing the packing hardware or packing rings, or when
loosening the packing box pipe plug.
D Check with your process or safety engineer for any additional measures that must be taken to protect against process
media.
Individual part key numbers and part descriptions referencedinthefollowingproceduresareshowninfigure6except
where otherwise indicated.
Lubrication
The interior parts of a 1077 actuator should be lubricated on a regular schedule with a quality gear lubricant. The
interior parts should also be lubricated whenever difficulty in handwheel rotation indicates a need for l ubrication.
To lubricate the 1077 actuator, perform the following steps:
1. Note the location of the travel indicator pointer in relation to the indicator dial. When reassembling the actuator,
the travel indicator pointer must be returned to its original position. Remove the machine screws and the travel
indicator pointer.
2. For a size 0-KE actuator only, remove the O-ring grease seal from the hub of the drive sleeve gear.
3. Removethecapscrewswhichsecurethegearboxcoverplateandremovethegearboxcoverplate.
4. Coat the worm, the drive sleeve gear teeth, and the bearing surfaces of the gearbox housing and worm with a
quality gear lubricant.
