Design V150 Valve
Introduction
Description
Scope of Manual
The Type 1077 manual-only handwheel actuator
(figure 1) is used with rotary-shaft valves such as the
9500 butterfly valve, Type 8532 and 8560 eccentric
disc valves, Design V150, V200 and V300 Vee-BallR
valves, Design V250 valves, and Design CV500 and
V500 eccentric plug valves. In the Type 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.
This instruction manual includes installation,
adjustment, operation, and maintenance information
for the Type 1077 manual handwheel actuator.
Instructions for the control valve is included in a
separate manual.
Do not install, operate or maintain a Type 1077
actuator without first D being fully trained and
qualified in valve, actuator and accessory
installation, operation and maintenance, and D
carefully reading and understanding the contents of
this manual. If you have any questions concerning
these instructions, contact your Emerson Process
Managementt sales office before proceeding.

figure 2.
Installation
The Type 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

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 that the
drive sleeve gear and travel indicator are rotated
fully clockwise.
For reverse acting turn the handwheel so that 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 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 with the appropriate
drive sleeve gear hub index mark such that the
connector keyway will be in line with the valve
shaft keyway.

5. Making certain that index mark alignment is
correct, slide the actuator onto the valve shaft in the
desired mounting position (figure 4 or 5). Check to
be sure the valve shaft index mark is still aligned
with the proper gear hub index mark.
6. Check the alignment of the mounting holes in the
mounting yoke (key 2) with those in the valve body.
If the holes are not aligned, rotate the handwheel to
allow repositioning of the yoke. It may be necessary
to loosen the hex nuts and back out the travel stop
set screws (key 10) to allow this repositioning.
7. When hole alignment is correct, secure the
mounting yoke to the valve body with washers
(key 4) and the valve body cap screws (key 9).

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. Install the valve body and actuator in the pipeline
by following the instructions in the separate valve
body 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 to 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
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.

whenever difficulty in handwheel rotation indicates a
need for lubrication.
Maintenance
WARNING
To lubricate the Type 1077 actuator, perform the
following steps:
Avoid personal injury or property
damage from sudden release of
process pressure or bursting of parts.
Before performing any maintenance
operations:
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.
D Always wear protective gloves,
clothing, and eyewear when
performing any maintenance
operations to avoid personal injury.
2. For a size 0-KE actuator only, remove the O-ring
grease seal from the hub of the drive sleeve gear.
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
referenced in the following procedures are shown in
figure 6 except where otherwise indicated.
3. Remove the cap screws which secure the
gearbox cover plate and remove the gearbox cover
plate.
4. Coat the worm, the drive sleeve gear teeth, and
the bearing surfaces of the gearbox housing and
worm with a quality gear lubricant.
5. Install the cover on the gearbox (key 1) and
secure it with the cap screws.
6. For a size O-KE only, install the the O-ring
grease seal onto the hub of the drive sleeve gear.
7. Attach the travel indicator pointer so that it
indicates the same point of rotation as was noted
before the pointer was removed. Secure the pointer
with the machine screws.
Disassembly
Parts are subject to normal wear and must be
inspected periodically. The following procedure
describes actuator disassembly for general
inspection and replacement of the drive sleeve gear.
Note
In order to remove the drive sleeve
gear, it is necessary to first remove the
actuator input shaft and worm.
1. Remove the pin (key 6) and the handwheel
(key 5).
2. For a size 10-KE:6 actuator only, remove the cap
screws which secure the reduction drive (item not
shown) and slide the reduction drive off the input
shaft.
Lubrication
3. Perform steps 1, 2, and 3 of the lubrication
procedure above.
The interior parts of a Type 1077 actuator should be
lubricated on a regular schedule with a quality gear
lubricant. The interior parts should also be lubricated
4. Remove the pin which secures the worm to the
input shaft by following the appropriate procedure for
the actuator size:

1077 Actuator
For a size 0-KE or 2-KE actuator, drive the
pin into the shaft (the pin length is less than the shaft
diameter). Remove the input shaft from the actuator
housing and drive the pin out of the shaft.
For a size 6-KE actuator, rotate the input
shaft so that the pin may be driven through the soft
plug (item not shown) on the back side of the
gearbox housing.
For a size 7-KE, 9-KE, or 10-KE:6 actuator,
there is sufficient clearance in the gearbox housing
to drive the pin through the shaft. Rotate the input
shaft so that the pin will emerge on the drive sleeve
gear side of the shaft and carefully drive the pin out
of the shaft.
5. Remove the input shaft and push the worm away
from the drive sleeve gear.
6. Carefully noting the position of the index marks
on the drive sleeve gear hub, remove the drive
sleeve gear.
D The bearing surfaces of the
gearbox housing, worm and input
shaft.
1. Install the worm and any shims and thrust
bearings into the gearbox casing. Keep the worm at
the maximum possible distance from the installed
position of the drive sleeve gear.
2. Install the drive sleeve gear onto the splined
valve shaft. Be sure that the index marks are aligned
as they were prior to disassembly.
3. Noting the position of the pin holes and the
original position of all shims and thrust bearings,
install the actuator input shaft into the bore of the
worm.
4. Make sure that the pin holes are aligned and
install the worm pin. Be certain that the pin does not
