Scope of Manual
This manual provides instructions for Styles H & J
mounting adaptations used to mount Fisher rotary actuators on other valves, or on other devices not
manufactured by Fisher. This instruction manual includes installation, adjustment, operation, maintenance, and parts ordering information for the Type
1051 (sizes 30, 40, and 60) and Type 1052 (sizes 30,
40, 60, and 70) diaphragm rotary actuators with H and
J mounting adaptations (see figures 1 and 2). Also,
this instruction manual provides information for the
optional top-mounted handwheel, and both the optional up and down travel stops. Instructions for the control valve body, the positioner, and accessories are
covered in separate manuals. Instructions for the control valve body, the positioner, accessories, and other
sizes or constructions of this actuator are covered in
separate manuals.
Only personnel qualified through training or experience
should install, operate, and maintain this actuator. If
there are any questions concerning these instructions
Description
The Type 1051 and 1052 diaphragm rotary actuators
are pneumatic spring-return actuators for use with
rotary-control valves and other equipment. The Type
1051 actuator can be used for on-off service, or it can
be used for throttling service when equipped with a
valve positioner. The Type 1052 actuator can be used
for on-off service, or it can be used for throttling service when equipped with or without a valve positioner.
The Type 1052 actuator spring is adjustable.
The H mounting adaptation permits the actuator to be
used with user-provided mounting brackets and couplings for rotary actuation of equipment other than
Fisher valve bodies. This mounting adaptation includes a flat-surface mounting plate that is drilled and
tapped for attaching the user-provided bracket. Cap
screws for attaching the bracket are provided. H
mounting also includes an output shaft (with milled
flats) to provide the rotary output either directly or
through a user-provided coupling

diameters and torque limits are listed in table 2. Dimensional information for the mounting plate and output shaft are shown in figures 4 and 5.
The J mounting adaptation permits the actuator to be
used for rotary actuation of Fisher keyed-shaft butterfly valve bodies and other keyed-shaft equipment. This
mounting adaptation uses the standard butterfly valve
mounting bracket and provides an output shaft with an
attached coupling for keyed equipment shafts. Coupling sizes and torque limits are listed in table 3. Dimensional information for the mounting yoke and stub
shaft coupling is shown in figures 4 and 5.
Additionally with Type 1051 and 1052 actuators, the
top-mounted handwheel can be applied for infrequent
service as a manual handwheel actuator. For more
frequent manual operation, a side-mounted handwheel
actuator is available. Also, an adjustable up travel stop
can be added to limit the actuator stroke in the upward
direction, or an adjustable down travel stop can be
added to limit actuator stroke in the downward direction.
Specifications
Specifications are shown in table 1 for Type 1051 and
1052 actuators. Specifications for a given Type 1051
or 1052 actuator as it originally comes from the factory
are stamped on a nameplate (figure 3) attached to the
actuator.

1. For an actuator with an H mounting adaptation,
attach an appropriate mounting bracket (not provided)
to the mounting plate (key 22) with the cap screws
(key 78). See figures 4 and 5 for mounting dimensions
on the mounting plate. Tighten the cap screws to 17
foot-pounds torque (23 Nm) for 7/8-inch (22.2 mm)
output shafts, 30 foot-pounds torque (41 Nm) for 1-1/8
inch (28.6 mm) output shafts, and 75 foot-pounds
torque (102 Nm) for 1-1/2 and 2-inch (38.1 and 50.8
mm) output shafts.
2. Consult figure 7 for available mounting styles and
positions. The actuator is normally positioned vertically
with the valve body or other equipment in a horizontal
pipeline.

Figure 6. Center of Gravity Dimensions
Note
For an actuator with an H mounting
adaptation and a 7/8 through 1-1/2 inch
(22.2 through 38.1 mm) output shaft,
find dimensions and center of gravity
information in figures 4, 5, and 6, and
approximate weights in table 4. This information is required for proper fabrication of the user-provided bracket and
coupling.
If the milled flats or the coupling on the
end of the actuator output shaft (key 87)
are oriented such that the output shaft
cannot accommodate the operated
equipment shaft, refer to the Changing
Positions portion of the Changing Actuator Mounting section. This procedure
describes how the output shaft can be
repositioned to accommodate the operated equipment shaft.
3. If using an actuator with a J mounting adaptation,
note that the valve shaft coupling (key 90) is furnished
with two keyways lettered A and B as shown in figure
8 (letters C and D on the coupling are not used and
can be disregarded). Align the appropriate keyway
with the keyway in the operated equipment shaft. If
using a Fisher butterfly valve body, align the appropriate keyway on the coupling with the valve shaft keyway indicated in table 5. Then install the woodruff key
(key 91) in the shaft keyseat, and slide the coupling
onto the shaft. It is helpful to apply a light coat of
grease to the inside of the coupling before sliding it
onto the shaft.
4. For an actuator with a J mounting adaptation, secure the mounting yoke (key 22) to the valve body with
the cap screws (key 78, not shown). Tighten the cap
screws to 30 foot-pounds torque (41 Nm) for 3/8
through 1-inch (9.5 through 25.4 mm) valve shafts and
to 100 foot-pounds torque (135 Nm) for 1-1/4 and
1-1/2 inch (31.8 and 38.1mm) valve shafts. For 1-1/4
and 1-1/2 inch (31.8 and 38.1 mm) valve shafts, also
place the two spacers (key 92, not shown) between
the mounting yoke and valve body during this step.

7. Follow the instructions given in the Adjustment section for turnbuckle adjustment before proceeding to the
loading connection portion of this section.
Loading Connection
1. Connect the loading pressure piping to the pressure connection in the top of the diaphragm casing.
For size 30 through 60 actuators, run either 1/4-inch
pipe or 3/8-inch tubing between the 1/4-inch pressure
connection and the positioner or automatic controller.
For size 70 actuators, run either pipe or tubing between the pressure connection and the positioner or
automatic controller. If necessary, remove the 1/4-inch
bushing in the pressure connection to increase connection size.
2. Keep the length of pipe or tubing as short as possible to avoid transmission lag in the control signal. If
an accessory (such as a volume booster or a positioner) is used, be sure that the accessory is properly connected to the actuator. If a positioner is part of the assembly, the pressure connection to the actuator will
normally be made at the factory.
3. When the actuator is completely installed and connected to the instrument, check for correct action (airto-open or air-to-close) to match the controlling instrument. For successful operation, the actuator stem and
operating shaft must move freely in response to the
loading pressure change on the diaphragm.
5. For an actuator with an H mounting adaptation and
a 7/8 through 1-1/2 inch (22.2 through 38.1 mm) output shaft, slide the actuator (with the user-provided
mounting bracket attached) into the user-provided
coupling on the operated shaft. Then, secure the actuator to the operated equipment in the desired mounting position with the appropriate fasteners, such as
mounting cap screws. See figures 4 and 5 for output
shaft dimensions.
6. For an actuator with an H mounting adaptation and
a 2-inch (50.8 mm) output shaft (key 87, figure 12),
note that the valve shaft coupling (key 90, figure 12) is
furnished with two keyways lettered A and B as shown
in figure 8 (letters C and D on the coupling are not
used and can be disregarded). Align the appropriate
keyway with the keyway in the operated equipment
shaft. Then, install the woodruff key (key 91, not
shown in figure 12) in the shaft keyseat, and slide the
coupling onto the shaft using the appropriate coupling
keyway (see table 5 and figure 8). It is helpful to apply
a light coat of grease to the inside of the coupling before sliding it onto the shaft. Secure the actuator (userprovided mounting bracket) to the operated equipment
in the desired mounting position with the appropriate
fasteners, such as mounting cap screws.
Adjustment
WARNING
Avoid personal injury or damage to
property from sudden release of process fluid. Before starting adjustment:
D Isolate the valve or other operated
equipment from the process,
D Release process pressure, and
D Vent the actuator loading pressure.
Type 1051 and 1052 Turnbuckle
Adjustment
Correct Turnbuckle adjustment ensures that the valve
body or other operated equipment is correctly closed
when the actuator is against its travel stops. The turnbuckle adjustment is the only adjustment necessary on
the Type 1051 actuator. Key numbers used in this procedure are shown in figure 10 for Type 1051 actuators
and in figure 11 for Type 1052 actuators.
