Description
The 1061 actuator is a pneumatic piston rotary actuator for use with rotary control valves and other equipment. 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 valves. The J mounting adaptation permits the actuator to be used for rotary
actuation of Fisher keyed‐shaft butterfly valves and other keyed‐shaft equipment that can mount on the actuator
yoke.
The H 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(1). Output shaft
diameters and torque limits are listed in table 2. Dimensional information for the mounting plate and output shaft are
shown in figure 2.
The J 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 output shaft coupling is shown in figure 2.
Additionally, the 1061 actuator can be used for either throttling or on‐off applications. For auxiliary manual operation
of the equipment, a side‐mounted handwheel actuator is available.
1. Actuators with H mounting and a 50.8 mm (2‐inch) output shaft are supplied with a
coupling for adaptation to either a 44.5 or 50.8 mm (1‐3/4 or 2‐inch) keyed shaft.

Installation
When an actuator and valve are shipped together, the actuator is normally mounted on the valve. Follow the valve
instructions when installing the control valve in the pipeline. If the actuator is shipped separately or if it is necessary to
mount the actuator on the valve, perform the procedures presented in the Actuator Mounting section.
WARNING
To avoid personal injury, always wear protective gloves, clothing, and eyewear when performing any installation
operations.
To avoid personal injury or property damage caused by bursting of pressure retaining parts, be certain the service
conditions do not exceed the limits given in table 1 or on the nameplate. Use pressure limiting or pressure relieving devices
to prevent the cylinder pressure from exceeding the maximum allowable cylinder operating pressure.
Check with your process or safety engineer for any additional measures that must be taken to protect against process
media.
If installing into an existing application, also refer to the WARNING at the beginning of the Maintenance section in this
instruction manual.

Actuator Mounting
Use the following steps to connect the actuator to a valve or other equipment. Unless otherwise specified, key
numbers are shown in figure 6.
WARNING
Perform the steps in the WARNING at the beginning of the Maintenance section.
Note
For an actuator with an H mounting adaptation and a 22.2 through 38.1 mm (7/8 through 1‐1/2 inch) output shaft, find
dimensions and center of gravity information in figures 2 and 3, and approximate weights in table 4. This information is required
for proper fabrication of the user‐provided bracket and coupling.
1. For an actuator with an H mounting adaptation, attach an appropriate mounting bracket (not provided) to the
mounting plate (key 23) with the cap screws (key 87). See figure 2 for mounting dimensions on the mounting plate.
2. Consult figure 4 for available mounting styles and positions. The actuator is normally positioned vertically with the
valve or other equipment in a horizontal pipeline.
Note
If the milled flats or the coupling on the end of the actuator output shaft (key 94) 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 97) is furnished with two
keyways lettered A & B as shown in figure 5 (letters C and D on the coupling are not used and can be disregarded).

Instruction Manual
D100325X012
1061 H & J Actuator

5
Align the appropriate keyway with the keyway in the operated equipment shaft. If using a Fisher butterfly valve,
align the appropriate keyway on the coupling with the valve shaft keyway indicated in table 5. Then, install the
woodruff key (key 98) 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 23) to the valve with the cap screws
(key 87, not shown). For 31.8 and 38.1 mm (1‐1/4 and 1‐1/2 inch) valve shafts, place two spacers (key 99, not
shown) between the mounting yoke and valve or other equipment during this step.
5. For an actuator with an H mounting adaptation and a 22.2 through 38.1 mm (7/8 through 1‐1/2 inch) 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
appropriate fasteners, such as mounting cap screws. See figure 2 for output shaft dimensions.
6. For an actuator with an H mounting adaptation and a 50.8 mm (2‐inch) output shaft (key 94, figure 7), note that
the valve shaft coupling (key 97, figure 7) is furnished with two keyways lettered A and B as shown in figure 5
(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 98, not shown in figure 7) in the shaft
keyseat, and slide the coupling onto the shaft using the appropriate coupling keyway (see table 5 and figure 5). 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 (user‐provided mounting bracket) to the operated equipment in the desired mounting position with
appropriate fasteners, such as mounting cap screws.
7. If the 1061 actuator is equipped with an auxiliary handwheel actuator, make certain that a cylinder bypass valve
(key 68, figure 8) is used to equalize cylinder pressure during handwheel operation. Operating the handwheel
actuator by itself against the force of differential cylinder pressures is difficult or even impossible. An installation of
a bypass valve is shown in figure 8.
CAUTION
Attempting to pneumatically operate the 1061 actuator while an auxiliary manual actuator is engaged could damage the
actuator shaft. Be certain the manual actuator is disengaged before pneumatically operating the 1061 actuator.
8. Follow the instructions given in the Adjustment section before proceeding to the loading connection portion of this
section.

Pressure Connections
1. If a positioner is used, the pressure connections to the actuator are normally made at the factory. Actuators without
positioners should have either a 4‐way solenoid valve or a switching valve connected to the pressure connections
located at the top and bottom of the actuator cylinder.
2. Connect either pipe or tubing between the actuator pressure connections and the positioner or automatic
controller. Keep the length of pipe or tubing as short as possible to avoid transmission lag in the control signal.

3. When the actuator is completely installed and connected to the instrument, check for correct action (air‐to‐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 piston.
Adjustment
WARNING
Perform the steps in the WARNING at the beginning of the Maintenance section.
The only adjustment on the 1061 actuator is to make sure that the valve or other operated equipment is correctly
closed when the actuator piston is against the travel stop. For accurate adjustment, the valve or other operated
equipment must be removed from the pipeline.
If the actuator is equipped with an auxiliary manual handwheel actuator, make sure that the manual actuator is
disengaged from the operated shaft and that the bypass valve (key 68, figure 8) is closed before performing
adjustment procedures.
Perform the following steps to adjust the actuator turnbuckle. A regulated air supply will be required to stroke the
actuator during this procedure. Also, when performing adjustment, refer to table 6 for the sizes of open‐end wrenches
required to loosen and tighten the hex nuts and turnbuckle. Key numbers referenced in this procedure are shown in
figure 6.
1. Remove the access plate (key 72). Also remove the machine screws (key 73) if present.
Note
The cover (key 34) supports the outer end of the output shaft and should not be removed during actuator adjustment.
2. Stroke the actuator until the lower hex nut (key 11) can be reached through the access opening. Loosen the hex
nut.
3. Stroke the actuator until the left‐hand threaded upper hex nut (key 71) can be reached through the access opening.
Loosen the hex nut.

4. Perform one of the following:
a. For push‐down‐to‐close action (extending piston rod closes operated equipment)‐‐ Slowly stroke the actuator to
the down travel stop. Consult the appropriate instruction manual for determining the closed position of the
valve or other operated equipment. Adjust the turnbuckle (key 70) until the closed position is reached. Lock this
adjustment with the left‐hand threaded hex nut (key 71). Stroke the actuator to the up travel stop, and tighten
the lower hex nut (key 11). Tighten each hex nut to the torque value listed in table 7.
b. For push‐down‐to‐open action (extending piston rod opens operated equipment)‐‐ Stroke the actuator to the up
travel stop. Consult the appropriate instruction manual for determining the closed position of the valve or other
operated equipment. Check the valve position with respect to its properly closed position. Stroke the actuator
until the turnbuckle (key 70) can be reached through the access opening. Adjust the linkage. Stroke the actuator
to the up travel stop again, and check the new adjustment. Continue this procedure until the operated
equipment is in the closed position when the actuator piston is resting against the up travel stop. Tighten the
lower hex nut (key 11). Stroke the actuator down, and tighten the left‐hand threaded hex nut (key 71). Tighten
each hex nut to the torque value listed in table 7.
5. Replace the access plate (key 72) and install the machine screws (key 73) if used.
Note
Skip the following step if an auxiliary handwheel actuator is mounted on the 1061 actuator.
6. Loosen the self‐tapping screws (key 39), and adjust the travel indicator (key 38). Retighten the self‐tapping screws.
CAUTION
If using a handwheel actuator, the splines of the 1061 actuator shaft could be damaged if excessive torque is applied to the
shaft by the manual actuator while the 1061 actuator is stopped at either end of travel. To protect the shaft, perform the
travel stop adjustment procedure found in the separate handwheel actuator instruction manual.
Principle of Operation
Piston movement is accomplished by loading air pressure on one side of the piston, and unloading air pressure from
the other side of the piston. If no positioner is used, a loading device, such as a 4‐way switching valve, must be
provided. Such a device is not furnished as part of the actuator.
Consult the separate positioner instruction manual for the 1061 actuator principle of operation with positioner.
Maintenance
Actuator parts are subject to normal wear and must be inspected and replaced as necessary. The frequency of
inspection and replacement depends upon the severity of service conditions. Instructions are given below for
disassembly and replacement of parts.
WARNING
Avoid personal injury or property damage from sudden release of process pressure or uncontrolled movement of parts.
Before performing any maintenance operations:

Instruction Manual
D100325X012
1061 H & J Actuator
January 2016
13
D Do not remove the actuator from the valve while the valve is still pressurized.
D Always wear protective gloves, clothing, and eyewear when performing any maintenance operations to avoid personal
injury.
D Disconnect any operating lines providing air pressure, electric power, or a control signal to the actuator. Be sure the
actuator cannot suddenly open or close the valve.
D Use 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.
D Vent the power actuator loading pressure and relieve any actuator spring precompression.
D Use lock‐out procedures to be sure that the above measures stay in effect while you work on the equipment.
D The valve packing box may contain process fluids that are pressurized, even when the valve has been removed from the
pipeline. Process fluids may spray out under pressure when removing the packing hardware or packing rings, or when
loosening the packing box pipe plug.
D Check with your process or safety engineer for any additional measures that must be taken to protect against process
media.
Disassembly
The following procedure describes how the actuator can be disassembled for inspection and replacement of parts.
When inspection or repairs are required, disassemble only those parts necessary to accomplish the job. Key numbers
referenced in this procedure are shown in figure 6 unless otherwise specified.
1. Bypass the valve or other operated equipment. Relieve all actuator loading pressure, and remove the tubing or pipe
from the top of the actuator.
2. Remove the positioner, if one is used.
3. Mark the orientation of the travel indicator (key 38) with respect to the travel indicator scale (key 36). Then,
unscrew the cap screws and washers (keys 35 and 76), and remove the cover (key 34). If a manual handwheel
actuator is used, it will be removed with the cover.
4. Remove the retaining ring (key 31), and slide the hub (key 30) from the cover (key 34) or, if a manual handwheel
actuator is used, remove the cover from the manual handwheel actuator connector. If disassembly of the manual
handwheel actuator is required, refer to the separate manual actuator instruction manual for instructions.
5. Check the condition of the bearing (key 32). If replacement of the bearing is necessary, the travel indicator scale
(key 36) must first be removed by removing the self‐tapping screws (key 37). Mark the orientation of the travel
indicator scale on the cover before removing it.
CAUTION
Do not use a hammer or similar tool to drive the lever (key 28) off the output shaft. Driving the lever could damage
operated equipment. For valves, driving the lever could move the valve disk and bearings away from the centered position
causing subsequent damage to valve parts.
If necessary, use a wheel puller to remove the lever. It is permissible to tap the wheel puller screw lightly to loosen the
lever, but hitting the screw with excessive force could damage the operated equipment.
6. For an actuator with an H mounting adaptation and a 22.2 through 38.1 mm (7/8 through 1‐1/2 inch) output shaft,
unscrew the cap screws (key 87) and remove the actuator from the operated equipment. Mark the orientation of
the lever (key 28) with respect to the output shaft (key 94). This marking is used during reassembly to allow for
proper lever/output shaft positioning. Then, loosen the cap screw (key 29) so that the output shaft is free to slide
off the lever. With the lever and output shaft properly marked, unscrew the cap screws (key 24) and remove the

remove the retaining ring (key 95) and separate the output shaft from the mounting plate. For 50.8 mm (2‐inch)
output shafts, refer to step 7 for this procedure.
7. For an actuator with either a J mounting adaptation (see figure 6), or an H mounting adaptation with a 50.8mm
(2‐inch) output shaft (see figure 7), proceed as follows:
Remove the cap screws (key 87, not shown in figure 6) and remove the actuator from the operated equipment. For an
actuator with J mounting and a 31.8 or 38.1 mm (1‐1/4 or 1‐1/2 inch) valve shaft diameter, two spacers (key 99, not
shown in figure 6) are also removed with the cap screws (key 87). When separating the output shaft (key 94) and
coupling (key 97) from the operated shaft, remember to remove the woodruff key (key 98, not shown in figure 7) from
the operated shaft keyway. Mark the orientation of the lever (key 28, figure 6) with respect to the output shaft (key
94). This marking is used during reassembly to allow for proper lever/output shaft positioning. Then, loosen the cap
screw (key 29, figure 6) so that the output shaft is free to slide off the lever. With the lever and output shaft properly
marked, unscrew the cap screws (key 24) and remove either the mounting yoke (key 23, figure 6 for J mounting) or the
mounting plate (key 23, figure 7 for H mounting) plus the attached output shaft (key 94) from the actuator housing
(key 21). If necessary, remove the retaining ring (key 95) and slide the mounting yoke or mounting plate off the output
shaft.
8. Check the bearing (key 81) in the mounting yoke or the mounting plate (key 23). Press out and replace the bearing
if necessary.
9. Heat the hex nut (key 14) to 177_C (350_F) long enough for the thread‐locking adhesive (medium strength (key
92) to lose its holding strength. Then, remove the cap screw and hex nut (keys 13 and 14), and remove the lever
(key 28) from the housing.
10. Remove the rod end bearing and the hex nut (keys 12 and 11), and then the turnbuckle and the hex nut (keys 70
and 71).

17. Follow the instructions in the Actuator Mounting portion of the Installation section for correct actuator mounting
and adjustment. Remember to replace the access plate (key 72) when performing these procedures.
Changing Actuator Mounting
The actuator is normally positioned vertically in a horizontal pipeline. However, there are two possible mounting styles
and four possible positions for each style (see figure 4). Key numbers referenced in the following procedures are
shown in figure 6 unless otherwise specified.
WARNING
Perform the steps in the WARNING at the beginning of the Maintenance section.
Use the following procedures along with figure 6 for key number references to convert from style A to style B or
vice‐versa or to change the mounting position.
Changing Styles
1. Unscrew the cap screws and washers (key 35 and 76), and remove the cover (key 34). If an optional manual
handwheel actuator is used, it will be removed with the cover.
2. Heat the hex nut (key 14) to 177_C (350_F) long enough for the thread locking adhesive (medium strength) (key
92) to lose its holding strength. Then, remove the cap screw and hex nut (keys 13 and 14).
3. Loosen the cap screw (key 29).
CAUTION
Do not use a hammer or similar tool to drive the lever (key 28) off the output shaft. Driving the lever could damage
operated equipment. For valves, driving the lever could move the valve disk and bearings away from the centered position
causing subsequent damage to valve parts.
If necessary, use a wheel puller to remove the lever. It is permissible to tap the wheel puller screw lightly to loosen the
lever, but hitting the screw with excessive force could damage the operated equipment.
4. Mark the side of the lever (key 28) that is nearest to the end of the output shaft (key 94). This marking is used during
reassembly to determine which side of the lever should be inserted into the actuator housing first. When the lever is
marked, remove the lever.
5. For an actuator with a J mounting adaptation,
a. Unscrew the cap screws (key 24), and remove the actuator housing (key 21) from the mounting yoke (key 23).

value listed in table 7.
7. Install the lever (key 28) as follows:
a. For push‐down‐to‐open action, rotate the operated equipment to the fully closed position.
b. For push‐down‐to‐close action, rotate the operated equipment to the fully open position.
c. With the operated equipment oriented correctly, slide the lever onto the output shaft (key 94) with the end
marked in step 4 inserted first. When installing the lever, align the bolt holes in the lever as close as possible with
the hole in the rod end bearing (key 12).
d. Temporarily rotate the lever and output shaft until the rod end bearing no longer interferes with further
installation of the lever. Then, slide the lever as far as it can go onto the output shaft. Clamp the lever to the
output shaft with the cap screw (key 29). Tighten the cap screw to the torque value listed in table 7.
e. Rotate the lever and output shaft back to the original position (i.e., operated equipment fully closed for
push‐down‐to‐open action or operated equipment fully open for push‐down‐to‐close action). Then, adjust the
rod end bearing so that it can be attached to the lever.
8. Apply thread‐locking adhesive (medium strength) (key 92) to the threads of the cap screw (key 13).
9. Connect the lever (key 28) and the rod end bearing (key 12) with the cap screw and hex nut (keys 13 and 14). This
connection can be aided by stroking the actuator from its up travel stop with a regulated air source. Tighten the cap
screw to the torque value listed in table 7.
10. Note the position of the valve or other operated equipment and direction of rotation.
a. Position the travel indicator (key 38) accordingly. Replace the cover (key 34), and secure it with the cap screws
and washers (keys 35 and 76). If the holes in the cover and housing (key 21) do not align, use a regulated air
source to move the actuator slightly off the up travel stop. If hole alignment cannot be obtained in this manner,
temporarily loosen the cap screws (key 24), and shift the housing slightly. Do not stroke the actuator while the
cover is off. Tighten both sets of cap screws to the torque values listed in table 7.
b. If a manual handwheel actuator is used, refer to the separate instruction manual for mounting instructions.
11. Follow the instructions in the Adjustment section for turnbuckle adjustment.
