Fisherr 1078 Declutchable Manual Actuator
Fisherr 1078 manual actuators, figures 1 and 2, are
declutchable actuators for manual operation of
control valves and equipment that use power
actuators. The 1078 manual actuator mounts directly
to Fisher 1051 sizes 33, 40, and 60; 1052 sizes 33,
40, 60, and 70; 1061 sizes 30, 40, 60, 68, 80, and
100; and to all sizes of 1066 and 1066SR actuators.

Mounted on a 1052 Size 33 Actuator
(Standard Construction)
For 1051 size 33, 1052 size 33, 1066, and 1066SR
actuators, coupling to the power actuator is via a
flatted shaft installed in the lever or hub. The
dimensions of these shafts are the same as those
used with H mounting adaptations. The stub shaft
fits into a square broach in the manual actuator
sector, and spacers secure the shaft in the
appropriate position.

(Standard construction is with the handwheel
shaft pointing down away from the power actuator
as shown in figure 1)

Handwheel Rotation
Clockwise handwheel rotation closes the valve.
Direct-acting units produce output rotation
matching input rotation; reverse-acting units
produce output rotation opposite input rotation.

Features
DDirect Attachment to the Power
ActuatorDirect mounting to the actuator housing
simplifies installation and eliminates the need for yokes
and other brackets.
DEngage Manual Actuator At Any Point of
RotationA lever-operated eccentric bearing
support on the input shaft allows engagement of the
worm gear with the sector at any point of rotation.
Because the travel indicator components are
mounted on a through shaft, accurate travel
indication is maintained during manual actuator
disengagement or engagement.
DPositive OperationThe disengagement
lever is locked in both the engaged and disengaged
positions by a detent mechanism, which must be
released before the lever can be moved. This
provision reduces the possibility of inadvertent or
accidental operation. In addition, stop-pins at the
fully engaged and fully disengaged positions provide
positive limits for lever travel. (Note that stop pins
are not available on 1078 size II-FA actuators.)

1. Requires flatted shaft as in the H mounting adaptation.
2. Field conversion of actuators for F and G mounting adaptations requires installation of new parts. The 1051 or 1052 Size 33 actuator requires installation of appropriate lever and stub
shaft. The 1066 actuator requires installation of appropriate hub assembly.
3. Compare table value with torque requirements of the valve plus the torque required to compress the power actuator spring (from Fisher Catalog 14). Note that dynamic torque of the
valve may have a positive or negative effect on total torque required.

Ordering Information
Whenever a power actuator is ordered with a 1078
manual actuator, all components are configured and
mounted according to specifications of the order.
Size AAA, AA, and A
Field installation of the 1078 onto existing actuators
with F or G mounting adaptations requires
installation of new power actuator parts. (The F and
G mounting adaptations are the mounting methods
normally used to mount 1051, 1052, 1066 and
1066SR actuators on Fisher valves.) For the 1051 or
1052 size 33, a lever with stub shaft must be
installed. For the 1066 or 1066SR actuator, a hub
assembly with stub shaft must be installed. Field
installation on power actuators with H mounting
adaptations requires dual stub shaft construction
(standard on the 1066 or 1066SR actuator). (The H
mounting adaptation is the mounting method
normally used to mount 1051, 1052, 1066 and
1066SR actuators on equipment and valves other
than Fisher valves.) Installation of a valve to bypass
cylinder or diaphragm pressure during manual
operation is also recommended.
Size 2A, 1A, B, C, D, and II-FA
Field installation of the 1078 onto the following
existing actuators with F or G mounting adaptations
[1051 (sizes 40 and 60), 1052 (sizes 40, 60, and 70),
and 1061 (sizes 30, 40, 60, 68, 80, and 100)]
requires additional parts in most cases. Remove the
cover and hub and then replace with the 1078
actuator. Most assemblies require a new lever and
splined adaptor.

1. Direct acting is when the clockwise handwheel rotation produces clockwise
valve shaft rotation to close the valve.
2. Reverse acting is when the clockwise handwheel rotation produces counter
clockwise valve shaft rotation to close the valve.
3. A left hand ball will be required for the NPS 3 through 12 series B and the NPS
14 through 20, with or without an attenuator.
When ordering, specify:
1. Power actuator type and size, and valve shaft
size.
2. Right or left hand mounting and desired mounting
position.
3. Direct or reverse acting manual actuator
construction. Refer to the mounting positions shown
in the appropriate actuator bulletin and order
according to the guidelines in table 7.
