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,
and 10-KE:6, a different actuator is required when
changing from 90-degree to 60-degree ball rotation.)
