1077 Handwheel Actuator
D101625X012
Fisherr 1077 Manual Handwheel
Rotary Actuator
Fisher 1077 manual-only handwheel actuator is for use
with rotary-shaft valves such as the 9500 butterfly
valve; 8532, 8560, and 8580 eccentric disc valves;
V150, V200 and V300 Vee-Ballt valves; V250 valves;
and CV500 and V500 valves. Figure 1 shows the
gearbox of the actuator. In this 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.

Features
Easy to Install and Maintain–Splined valve shaft
mates directly with the drive gear sleeve, reducing
the number of parts required and simplifying
installation and maintenance.
Easy to Operate–Handwheel rotation direction
required to open the valve disc or ball is marked on
the handwheel; the rotation indicator is marked in
bold print at the open and closed positions and with
bold incremental lines to indicate the valve disc or
ball position.
Consistency of Operation–When installed
according to instructions, clockwise handwheel
rotation closes the valve in all applications.
Accurate Valve Disc or Ball P ositioning–Travel stops
can be adjusted and locked in place to provide
accurate disc or ball positioning at closed
(0-degree) and open (90-degree) positions. Travel
stops for 60-degree operation may be used to
establish a disc or ball closing stop at any angle

between 0 and 30 degrees and/or to establish a disc or
ball opening stop at any angle between 60 and 90
degrees. This option is available on sizes 2-KE and 7-KE
as a set screw change. For sizes 0-KE, 6-KE, 9-KE, and
10-KE:6, a different actuator is required when
changing from 90-degree to 60-degree ball rotation.

Handwheel Rotation
Direct Acting Construction: Clockwise handwheel
rotation closes the valve (produces clockwise rotation
of the valve shaft) as shown in figure 2.
Reverse Acting Construction: Clockwise handwheel
rotation closes the valve (produces counterclockwise
rotation of the valve shaft) as shown in figure 2.
Maximum Output Rotation
Standard: 90 degrees
Optional: 60 degrees
J valve ball or disc closed
position may be set to any angle between 0 and 30
degrees, and/or
J valve ball or disc open position
may be set to any angle between 60 and 90 degrees.
(This option is available on actuator sizes 2-KE and
7-KE as a set screw change. For sizes 0-KE, 6-KE, 9-KE,

Ordering Information
When ordering, specify:
Application
1077 Handwheel Actuator
D101625X012
tables and figures. Indicate a choice whenever there is
a selection to be made.
1. Valve body type or design, size, and shaft diameter.
2. Valve disc or ball rotation (e.g., 0 to 60 or 0 to 90
degrees). For adjustability between 0 and 30 degrees
for the closed stop position, or for adjustability
between 60 and 90 degrees for the open stop position,
the 60-degree travel stop is used. This option is
available on actuator sizes 2-KE, 7-KE, 9-KE, and
10-KE:6 as a set screw change. For sizes 0-KE and 6-KE
a different actuator is required when changing from
90-degree to 60-degree ball rotation.
3. Right- or left-hand mounting and desired mounting
position from figure 3. If the control valve assembly is
to be used for bidirectional flow, assume that the flow
direction arrows in figure 3 point to the seal retainer or
flow ring end of the valve body.
Handwheel Actuator
Refer to the Specifications section. Review the
description for each specification and in the referenced
Note
When specifying a mounting position, make certain that the
handwheel diameter specified will not interfere with the
valve body, pipe flanges, or line bolting connected to the
system.
Accessories
If ordering limit switches, specify the number of
switches desired (one or two). For one limit switch,
specify whether switching is to occur at the open or
closed valve position.
Valve Body and Accessories
Refer to the separate valve body and accessory
information bulletins for ordering information.
