Description
The Type 1078 manual actuator, shown in figures 1
and 2, is a declutchable unit for manual operation of
control valves and equipment that use power actua-
tors. The Type 1078 manual actuator mounts directly
to Type 321 sizes 60 and 80; Type 354 sizes 60 and
80; Type 1051 sizes 33, 40, and 60; Type 1052 sizes
33, 40, 60, and 70; Type 1061 sizes 30, 40, 60, 68,
80, and 100; and to all sizes of Type 1066 or 1066SR
actuators. The Type 1078 manual actuator can be en-
gaged to allow manual operation of the valve when the
power actuator is not in use. It can be disengaged to
allow automatic operation of the valve by the power
actuator. The mechanism used allows manual actuator
engagement at any point of power actuator rotation.
For Type 1051 size 33, Type 1052 size 33, Type
1066, and Type 1066SR actuators, coupling to the
power actuator is via a flatted shaft installed in the le-
ver 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 ac-
tuator sector, and spacers secure the shaft in the ap-
propriate position.
H and J mounting adaptations are the mounting meth-
ods normally used to mount Type 1051, 1052, 1061,
1066 and 1066SR actuators on equipment and valves
not manufactured by Fisher Controls. F and G mount-
ing adaptations are the mounting methods normally
used to mount Type 1051, 1052, 1061, 1066 and
1066SR actuators on valves manufactured by Fisher
Controls.
For all sizes of the Type 1066 or 1066SR actuators,
coupling to the power actuator is in the hub of the
Type 1066 or 1066SR actuator.
Specifications
Type 1078 manual actuator specifications are given in
table 1. Specifications for a control valve assembly as
it comes from the factory appear on a nameplate at-
tached to the power actuator.

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 Type 1051 or 1052 Size 33 actuator requires installation of appropriate lever and
stub shaft. The Type 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 Controls Catalog 14). Note that dynamic torque of
the valve may have a positive or negative effect on total torque required.

Installation
The Type 1078 manual actuator is normally shipped
mounted on a power actuator. If the manual actuator
has been shipped separately for installation on a pow-
er actuator, or if the manual actuator was removed for
maintenance, mount the manual actuator by following
the instructions presented in this section.
Individual part key numbers and part descriptions ref-
erenced in this procedure are shown in figure 2.
Converting An Existing Power Actuator
For Use With The Type 1078 Manual
Actuator
Field conversion of a power actuator for use with the
Type 1078 manual actuator may require replacement
and/or removal of some parts. The procedures which
follow apply only to power actuators which were not
ordered specifically for use with the Type 1078 manual
actuator. Proceed as appropriate:
For manual actuator installation on a Type 1051 or
1052 size 33 power actuator with F or G mounting
adaptation without wrench-operated extension, a
new lever with stub shaft must be installed in place of
the standard lever. The standard power actuator travel
indicator components are omitted. Refer to the power
actuator instruction manual.
For manual actuator installation on a Type 1051 or
1052 size 33 power actuator with F or G mounting
adaptation with wrench-operated extension, the
manual actuator will mount directly to the power actua-
tor after the power actuator travel indicator compo-
nents have been removed from the power actuator.
For manual actuator installation on a Type 1051 or
1052 size 33 power actuator with H or J mounting
adaptation, dual stub shaft construction is required. If
the power actuator is a single stub shaft construction,
the lever must be removed and a second stub shaft
installed. The standard power actuator travel indicator
components are omitted. Refer to the power actuator
instruction manual. If the power actuator has dual stub
shaft construction (wrench-operated extension), the
manual actuator will mount directly to the power actua-
tor after the power actuator travel indicator compo-
nents have been removed from the power actuator.
For manual actuator installation on Type 1061
sizes 30, 40, 60, 68, 80, and 100; Type 1051 sizes
40 and 60; Type 1052 sizes 40, 60, and 70; Type
321 sizes 60 and 80; and Type 354 sizes 60 and 80
remove the actuator cover (key 34) and attached parts
from Type 1061, 1051, 1052, 321, or 354. Replace
with Type 1078. Most assemblies require installation
of a new lever and splined adaptor to complete the
installation. When used, the splined adaptor slides in-
side the new lever and the lever is then clamped onto
the splined adaptor. See figure 6.
CAUTION
The travel indicator scale supplied with
the Type 1066 and 1066SR power actua-
tor is thicker than the scale supplied
with the Type 1078 manual actuator. Be-
cause the scale serves as a pressure
containing and component positioning
part, it is imperative that the thicker
scale originally mounted on the Type
1066 and 1066SR be returned to its orig-
inal position before mounting the Type
1078 manual actuator. Failure to use the
thicker plate may result in damage to
internal components and unreliable per-
formance of the power actuator.
For manual actuator installation on a Type 1066 or
1066SR power actuator with F or G mounting
adaptation, a hub assembly with shaft extension must
be installed in place of the standard hub assembly.
Make certain that the travel indicator scale originally
supplied with the Type 1066 and 1066SR power ac-
tuator is installed on the power actuator before mount-
ing the Type 1078 manual actuator. The Type 1066
and 1066SR travel indicator scale is thicker than the
scale shipped with the Type 1078 manual actuator and
is used as a pressure retaining and component posi-
tioning part. The travel indicator pointer and its mount-
ing parts are not used. Refer to the power actuator
instruction manual.
For manual actuator installation on a Type 1066 or
1066SR power actuator with H mounting adapta-
tion, the manual actuator will mount directly to the
power actuator after the travel indicator pointer, travel
indicator pointer retaining ring, and the travel indicator
scale retaining ring have been removed from the
manual actuator side of the power actuator. Make cer-
tain that the travel indicator scale originally supplied
with the Type 1066 and 1066SR power actuator is
installed between the manual and power actuator.
Type 1066 and 1066SR travel indicator scale is thicker
than the scale shipped with the Type 1078 manual
actuator and is used as a pressure retaining and com-
ponent positioning part. The travel indicator pointer,
the travel indicator pointer retaining ring, and the travel
indicator scale retaining ring (quantity of 1) originally
installed on the manual actuator side of the power ac-
tuator are not used.

Type 1078

Installing the Manual Actuator
WARNING
Avoid personal injury from sudden re-
lease of process pressure or bursting of
parts. Before performing any mainte-
nance operations:
DDisconnect any operating lines pro-
viding air pressure, electric power, or a
control signal to the power actuator. Be
sure the actuator cannot suddenly open
or close the valve.
DUse bypass valves or completely
shut off the process to isolate the valve
from process pressure. Relieve process
pressure on both sides of the valve.
Drain the process media from both
sides of the valve.
DVent the power actuator loading
pressure and relieve any actuator spring
precompression.
DUse lock-out procedures to be sure
that the above measures stay in effect
while you work on the equipment.
CAUTION
Undertravel or overtravel of the valve
ball or disk, especially at the closed
position, may result in poor valve per-
formance and/or damage to the equip-
ment. Make certain that the power actua-
tor travel stops are properly set before
installing and adjusting the manual ac-
tuator. Refer to the instruction manuals
for the valve and the power actuator for
information about setting travel stops.
1. Isolate the control valve from the line pressure, re-
lease pressure from both sides of the valve body, and
drain the process media from both sides of the valve.
Also shut off all pressure lines to the power actuator
and release all pressure from the power actuator. Use
lock-out procedures to be sure that the above mea-
sures stay in effect while you work on the equipment.
2. Make certain that the power actuator travel stops
have been properly set according to the caution given
above.
3. For spring-return power actuators, allow the power
actuator to remain in the position where the spring is
relaxed. For double-acting power actuators, apply sup-
ply pressure as appropriate to position the valve disk
or ball in either the open or closed position.
4. Note whether the valve disk or ball is in the open or
closed position.
5. Rotate the handwheel to move the drive sleeve
gear and travel indicator to the position that corre-
sponds with the position of the valve disk or ball. For
both direct and reverse acting manual actuators,
clockwise handwheel rotation sets the manual actuator
to the closed position. Counterclockwise handwheel
rotation sets the manual actuator to the open position.
Proceed as appropriate to step 6 or step 16.
For Type 1051 (size 33), 1052 (size 33), and 1066
and 1066SR (all sizes).
6. Remove the machine screws and the travel indica-
tor pointer (keys 6 and 5). Remove the travel indicator
scale and gear box cover plate.
7. Slide the manual actuator over the power actuator
stub shaft.
8. Install the spacers (figure 2) to secure the flatted
shaft in the drive gear sleeve. Use the handwheel to
position the drive sleeve gear if necessary.
9. Disengage the manual actuator.
10. Install the manual actuator, the gearbox cover
plate, and the travel indicator scale on the power ac-
tuator with the cap screws provided. Prior to tightening
the cap screws to a final torque value, the power ac-
tuator will be stroked to center the manual actuator.
Therefore, the cap screws must be tightened to the
degree that they will keep the manual actuator in posi-
tion while allowing some minor movement for center-
ing during the stroking operation.
11. Apply supply pressure to the power actuator and
fully stroke the power actuator through its range.
Tighten the cap screws which secure the manual ac-
tuator to the power actuator, but do not apply final
torque. Repositioning of the manual actuator should
be allowed during the next step.
12. To complete the centering procedure, stroke the
power actuator to the other end of its stroking range
and apply the final torque value to the cap screws.
13. Cycle the power actuator several times and check
the power actuator and manual actuator for free op-
eration. If there is evidence of binding or other mal-
function, loosen the manual actuator and repeat the
centering operation beginning with step 10 above.
14. Install the travel indicator pointer so that it indi-
cates the true position of the valve ball or disk.
15. For double-acting power actuators, be certain the
power actuator is equipped with a bypass valve. Oper-
ating the handwheel mechanism against the force of
differential cylinder pressures will be difficult or impos-
sible.
For Type 1051 (sizes 40 and 60), Type 1052 (sizes
40, 60, and 70), Type 1061 (sizes 30, 40, 60, 68, 80,

Type 1078
10
and 100), Type 321 sizes 60 and 80 and Type 354
sizes 60 and 80.
16. Remove the lever and add a new lever and
splined adaptor when needed. See figure 6.
The splined adaptor slides inside the new lever and
the lever is then clamped onto the splined adaptor.
17. Disengage the manual actuator.
18. Install the manual actuator
19. Tighten the cap screws to the final torque value.
20. For double-acting power actuators, be certain the
power actuator is equipped with a bypass valve. Oper-
ating the handwheel mechanism against the force of
differential cylinder pressures will be difficult or impos-
sible.
Operation
After the travel indicator pointer has been adjusted
and the control valve assembly installed, the manual
actuator is ready for operation.
CAUTION
Applying too much torque to the actua-
tor and valve parts could cause damage
to the parts. To avoid such damage, 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 de-
vices on the handwheel or handwheel
shaft to increase operating force.
If the force required to rotate the handwheel exceeds
the wheel-rim force listed in table 2, refer to the main-
tenance procedure.
Engaging and Disengaging the Manual
Actuator
Engaging the Manual Actuator
1. Shut off the supply pressure to the power actuator.
2. Pull the ring on the detent mechanism to unlock the
lever. Move the lever into the engaged position until it
is against the stop pin and locked in position by the
detent mechanism. (Note that stop pins are not avail-
able on Type 1078 size II-FA actuators.)
3. If applicable, open the power actuator bypass
valve.
Disengaging the Manual Actuator
CAUTION
Disengaging the manual actuator when
forces such as spring compression, cyl-
inder pressure, and dynamic torque are
present may cause sudden, extreme
movement of all control valve compo-
nents. This can result in damage to
equipment and violent disturbance of
the process. Before disengaging the
manual actuator, take appropriate steps
to ensure that the return to automatic
operation will not result in an extreme
repositioning of control valve compo-
nents. Procedures to determine approxi-
mate system balance are given in the
following steps.
1. Before disengaging the manual actuator, approxi-
mate system balance should be achieved. The system
is in balance when the actual valve ball or disk position
is approximately the same as the position requested
by the automatic control system. Under balanced sys-
tem conditions, the manual actuator disengaging lever
moves freely without use of excessive force. If after
releasing the detent mechanism, the lever does not
move freely toward the disengaged position, some
system force is causing an imbalance. A forced return
to automatic operation under these conditions can
cause serious damage to the equipment and violent
disturbance of the process.
2. If possible, determine whether the automatic con-
trol system is tending to open or close the valve ball or
disk, and rotate the handwheel in the appropriate
direction until friction in the manual operator is re-
duced and the lever can be easily moved by hand. As
an alternate approach, local manipulation of the supply
pressure to the power actuator may bring the set point
of the automatic system closer to the actual valve ball
or disk position.
3. If a smooth transition from manual to automatic
operation cannot be ensured, isolate the valve from
the process. Position the manual actuator so that it
matches the position of the ball or disk when no supply
pressure is applied to the power actuator.
4. Pull the ring on the detent mechanism to unlock the
lever. Push the lever into the disengaged position until
it is against the stop pin and locked in position by the
detent mechanism. (Note that stop pins are not avail-
able on Type 1078 size II-FA actuators.)
5. Close the bypass valve and return supply pressure
to the power actuator.

Type 1078
11
Maintenance
If the force required to rotate the handwheel exceeds
the wheel-rim force listed in table 2, check for the fol-
lowing conditions:
DInsufficient lubrication,
DSeized actuator parts,
DExcessive pressure drop across the valve body, or
DObstruction to the valve disk or ball rotation.
If the manual actuator does not seem to control the
process fluid, the worm or drive sleeve gear teeth may
be broken, the pin (key 3) may be sheared, or the in-
ternal power actuator or valve parts may be broken.
Purchase a replacement manual actuator if necessary.
Refer to the power actuator and valve instruction
manuals if power actuator or valve maintenance is
needed.
Lubrication
The interior parts of the Type 1078 manual actuator
should be lubricated on a regular schedule with a qual-
ity gear lubricant. The interior parts should also be lu-
bricated whenever difficulty in handwheel rotation indi-
cates a need for lubrication.
WARNING
Avoid personal injury from sudden re-
lease of process pressure or uncon-
trolled movement of parts. Before per-
forming any maintenance operations:
DDisconnect any operating lines pro-
viding air pressure, electric power, or a
control signal to the power actuator. Be
sure the actuator cannot suddenly open
or close the valve.
DUse 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.
DVent the power actuator loading
pressure and relieve any actuator spring
precompression.
DUse lock-out procedures to be sure
that the above measures stay in effect
while you work on the equipment.
1. Isolate the control valve from the line pressure, re-
lease pressure from both sides of the valve body, and
drain the process media from both sides of the valve.
If using a power actuator, also shut off all pressure
lines to the power actuator, release all pressure from
the actuator. Use lock-out procedures to be sure that
the above measures stay in effect while you work on
the equipment.
2. Mark the position of the travel indicator pointer on
the indicator dial. The travel indicator pointer must be
returned to its original position when assembling the
manual actuator. Remove the machine screws and the
travel indicator pointer.
3. For Type 1051 (size 33), 1052 (size 33), and
1066 and 1066SR (all sizes), remove the cap screws
which secure the manual actuator to the power actua-
tor and remove the manual actuator.
For Type 1051 (sizes 40 and 60), 1052 (sizes 40, 60,
and 70), 1061 (sizes 30, 40, 60, 68, 80, and 100),
321 (sizes 60 and 80), and 354 (sizes 60 and 80),
remove the manual actuator cover screws.
4. Remove the travel indicator scale and the gearbox
cover plate. 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 plate and the travel indicator scale
on the gearbox.
6. For Type 1051 (size 33), 1052 (size 33), and
