Description
1051 and 1052 diaphragm rotary actuators are pneumatic spring-return actuators for use with rotary-control valves
and other equipment. The 1051 actuator can be used for on-off service, or it can be used for throttling service when
equipped with a valve positioner. The 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 1052 actuator spring is adjustable.
The H mounting adaptation permits the actuator to be used with equipment other than Fisher valve bodies. The
mounting brackets and couplings for rotary actuation are user-provided. 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 Double D rotary
output either directly or through a user-provided coupling. Output shaft diameters and torque limits are listed in table
2. Dimensional information for the mounting plate and output shaft are shown in figures 4, 5, and 6.

Figure 2. Fisher 1052 Actuator with J Mounting Adaptation
W4139-1
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 bracket and stub shaft coupling is shown in
figures 4, 5, and 7.
Additionally, a 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 1051 and 1052 actuators. Specifications for a given 1051 or 1052 actuator as it
originally comes from the factory are stamped on a nameplate attached to the actuator.

Principle of Operation
The diaphragm rod moves down as loading pressure is increased on top of the diaphragm. As the loading pressure is
decreased, the spring forces the diaphragm rod upward.
The spring and diaphragm have been selected to meet the requirements of the application and, in service, the
actuator should produce full travel of the valve or other operated equipment with the diaphragm pressure as indicated
on the nameplate.
Consult the separate positioner instruction manual for actuator principle of operation with positioner.
Installation
WARNING
Always wear protective gloves, clothing, and eyewear when performing any maintenance operations to avoid personal
injury.
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. Use pressure limiting or pressure relieving devices to prevent the
diaphragm sizing pressure from exceeding the maximum allowable diaphragm sizing 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.

WARNING
To avoid personal injury or parts damage, do not use an operating pressure that exceeds the Maximum Diaphragm Casing
Pressure (table 1) or produces a torque greater than the Maximum Allowable Valve Shaft Torque (see Catalog 14). Use
pressure-limiting or pressure-relieving devices to prevent the diaphragm casing pressure from exceeding its limit.

Actuator Mounting
Use the following steps to connect the actuator to a valve body or other equipment. Unless otherwise specified, key
numbers are shown in figures 12 and 13. Mounting dimensions are shown in figures 4, 5, 6, and 7.
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 3, 4, 5, 6, and 9, and approximate weights in table 8. 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 22) with the cap screws (key 78). See figures 4, 5, and 6 for mounting dimensions on the
mounting plate. Tighten the cap screws to the bolt torques listed in table 4.
2. Consult figure 10 for available mounting styles and positions. The actuator is normally positioned vertically with the
valve body or other equipment in a horizontal pipeline.

Note
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 and 12 (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, align the appropriate keyway on the coupling with the valve shaft keyway indicated in table 9. 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 an H mounting adaptation, 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, 5 and 6 for output shaft dimensions.
5. For an actuator with a J mounting adaptation, secure the mounting bracket (key 22) to the valve body with the cap
screws (key 78, not shown). Tighten the cap screws to the bolt torques in table 4. For 31.8 and 38.1 mm (1-1/4 and
1-1/2 inch) valve shafts, also place the two spacers (key 92, not shown) between the mounting bracket and valve
body during this step.
6. For an actuator with a J mounting adaptation and a 50.8 mm (2-inch) output shaft (key 87, figure 14), note that the
valve shaft coupling (key 90, figure 14) 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 14) in the shaft keyseat, and
slide the coupling onto the shaft using the appropriate coupling keyway (see table 9 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
(user-provided mounting bracket) to the operated equipment in the desired mounting position with the
appropriate fasteners, such as mounting cap screws.
7. Follow the instructions given in the Turnbuckle Adjustment section 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 40 through 60 actuators, run either NPS 1/4 pipe or 3/8-inch tubing between the NPT 1/4 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 (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 diaphragm.

Adjustment
WARNING
Before performing any adjustment steps, follow the steps in the WARNING at the beginning of the Maintenance section.
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 1051 actuator.
Key numbers used in this procedure are shown in figure 12 for 1051 actuators and in figure 13 for 1052 actuators.
For accurate adjustment, remove the valve body or other operated equipment from the pipeline.
A regulated air supply will be required to stroke the actuator. Consult table 10 for the sizes of the three open end
wrenches required for this procedure.
1. Remove the access plate (key 59). Also remove the machine screws (key 60), if present.
Note
For the most accurate adjustment of the actuator, do not remove the cover (key 33) during this procedure.
2. Loosen the lower locknut (key 16).

3. Make sure the actuator housing (key 20) is clear of any tools or other instruments that could obstruct the actuator
stroke path. Pressure the diaphragm casing enough to stroke the actuator down so that the left-hand threaded
upper locknut (key 58) is accessible through the access opening. Loosen the locknut.
4. Use one of the following:
a. For push-down-to-close action–Slowly stroke the actuator to the down travel stop. Consult the appropriate
instruction manual for determining the closed position of the valve body or other operated equipment. Adjust
the turnbuckle (key 57) until the closed position is reached. Lock this adjustment with the left-hand threaded
locknut (key 58). Stroke the actuator to the mid-travel position, and tighten the locknut (key 16). Tighten each
locknut to the appropriate torque value listed in table 11.
WARNING
Exceeding any torque requirements could damage the actuator and impair safe operation.
13
1051 and 1052 H & J Actuators
October 2012
Instruction Manual
D100320X012
b. For push-down-to-open action–Consult the appropriate instruction manual for determining the closed position
of the valve or other operated equipment. Release all pressure from the diaphragm casing, making sure the
diaphragm is against its up travel stop. Be sure that the optional handwheel is adjusted to its topmost position so
that the closed position of the actuator and valve body or other operated equipment can be reached
simultaneously. Check the position of the valve body or other operated equipment with respect to its properly
closed position. Stroke the actuator so the turnbuckle (key 57) is accessible through the access opening. Adjust
the linkage. Release pressure to the actuator, and check the new adjustment. Continue this procedure until the
operated equipment is in the closed position when the actuator is resting on its up travel stop. Tighten locknut
(key 16). Stroke the actuator, and tighten the left-hand threaded locknut (key 58). Tighten each locknut to the
appropriate torque value listed in table 11.
WARNING
Exceeding any torque requirements could damage the actuator and impair safe operation.
5. Replace the access plate (key 59). Also, replace the machine screws (key 60), if present.
6. Loosen the self-tapping screws (key 38), and adjust the travel indicator (key 37). Retighten the self-tapping screws.
1052 Spring Adjustment
Initial Compression
The 1052 nameplate specifies a spring set, which is the initial compression adjusted into the actuator spring, Initial
compression is the casing pressure at which the diaphragm and diaphragm rod begin to move away from the up travel
stop with the actuator disconnected from the valve body or other operated equipment. (With the actuator connected
and pressure applied to the valve body or other operated equipment, a higher casing pressure will be required to start
actuator travel). The initial compression was selected (based upon the service conditions specified when the actuator
was ordered) so that when the actuator and valve body or other operated equipment are in service, the operated
equipment will close properly and full travel will be obtained within a diaphragm casing pressure range of 0 to 1.2, 0 to
2.3, 0 to 2.8 or 0 to 3.8 bar (0 to 18, 0 to 33, 0 to 40, or 0 to 55 psig) depending on specific actuator size and
construction.
If the actuator has been disassembled or if the spring adjustment was changed, and it is desired to match the initial
compression stated on the nameplate, make sure the rod end bearing (key 17, figure 13) has been disconnected from
the lever (key 27, figure 13). Adjust the spring so that the diaphragm rod just starts to travel at the spring set pressure
specified on the nameplate. Be sure the rod end bearing does not hit the lever as the diaphragm and diaphragm rod
move away from the up travel stop.
To adjust the spring, insert a round rod into one of the slots in the lower bearing seat (key 73, figure 13). Slot diameter
is 9.5 mm (3/8-inch) for size 40 actuators, 15.9 mm (5/8-inch) for size 60 actuators, and 19.1 mm (3/4-inch) for size 70
actuators.
Rotate the bearing seat to move it toward the casings (keys 1 and 2, figure 13) to increase initial compression or away
from the casings to decrease initial compression.

1. Exceeding any torque requirements could damage the actuator and impair safe operation.
Stroking Range
The initial spring set listed on the nameplate has been determined to be the optimum setting, and it is not
recommended to make spring adjustments that will cause this value to change or be exceeded. For
push-down-to-open (PDTO) action, the initial spring set is normally the maximum allowable to provide the maximum
spring closing force. Any increase of this setting could over-stress the spring at full travel. For push-down-to-close
(PDTC) action, the initial spring set has been determined to be the optimum balance between the air to close and the
spring to open breakout torque.
If the 1052 actuator is to be changed from one action to another (i.e., from PDTC to PDTO), first refer to the initial
spring compression values listed in the table for keys 11 and 13 in the Parts List section. Then adjust the unit according
to the procedures in the Initial Compression portion of this section.
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 assembly of parts. Key numbers referenced in the following steps are shown in figure 12 for 1051
actuators and in figure 13 for 1052 actuators unless otherwise specified.
WARNING
Avoid personal injury or property damage from sudden release of process pressure or uncontrolled movement of parts.
Before performing any maintenance operations:
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.
15
1051 and 1052 H & J Actuators
October 2012
Instruction Manual
D100320X012
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 completely disassembled. When inspection or repairs are
required, perform only those steps necessary to accomplish the procedure. Do not under ordinary circumstances
remove the cap screws (keys 7, 8, and 21).
CAUTION
Cap screw (key 18) must be disengaged from the lever (key 27) before removing the diaphragm casing (key 1). Failure to do
so will allow the spring precompression to rotate the valve body or other operated equipment beyond its fully open or
closed position. This could cause damage to the operated equipment.
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 37) with respect to the travel indicator scale (key 35). Then,
unscrew the cap screws and washers (keys 34 and 63), and remove the cover (key 33).
4. Remove the retaining ring (key 30), and then remove the hub (key 29) from the cover.
5. Check the condition of the bearing (key 31). If replacement of the bearing is necessary, the travel indicator scale
(key 35) must first be removed by removing the self-tapping screws (key 36). Mark the orientation of the travel
indicator scale on the cover before removing it.
CAUTION
When removing the actuator from the valve body, do not use a hammer or similar tool to drive the lever (key 27) or
actuator off the output shaft (key 87). Driving the lever or actuator could damage operated equipment. For valves, driving
the lever (key 27) could move the valve disc 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 also damage operated parts or disrupt the centered position of a
valve disc or other 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 78) and remove the actuator from the operated equipment. Mark the orientation of
the lever (key 27) with respect to the output shaft (key 87). This marking is used during reassembly to allow for
proper lever/output shaft positioning.
16
Instruction Manual
1051 and 1052 H & J Actuators
D100320X012
October 2012
Then, loosen the cap screw (key 28) 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 23) and remove the mounting plate (key 22) and output shaft (key
87) assembly from the actuator housing (key 20). If necessary, remove the retaining ring (key 88) and separate the
output shaft from the mounting plate.
7. For an actuator with a J mounting adaptation (see figures 12 and 13) with a 50.8 mm (2-inch) output shaft (see
figure 14) and proceed as follows:
a. Remove the cap screws (key 78, not shown in figures 12 and 13) 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 92, not shown in figures 12 and 13) are also removed with the cap screws (key 78).
b. When separating the output shaft (key 87) and coupling (key 90) from the operated shaft, remember to remove
the woodruff key (key 91, not shown in figure 14) from the operated shaft keyway.
c. Mark the orientation of the lever (key 27, figures 12 and 13) with respect to the output shaft (key 87). This
marking is used during reassembly to allow for proper lever/output shaft positioning,
d. Loosen the cap screw (key 28, figures 12 and 13) so that the output shaft is free to slide off the lever.
e. With the lever and output shaft properly marked, unscrew the cap screws (key 23) and remove either the
mounting bracket (key 22, figures 12 and 13 for J mounting) or the mounting plate (key 22, figure 14 for H
mounting) plus the attached output shaft (key 87) from the actuator housing (key 20).
f. If necessary, remove the retaining ring (key 88) and slide the mounting bracket or mounting plate off the output
shaft.
8. Check the bearing (key 67) in the mounting bracket or mounting plate (key 22). Press out and replace the bearing if
necessary.
9. Heat the hex nut (key 19) to 177_C (350_F) long enough for the thread-locking adhesive (high strength) (key 77) to
lose its holding strength. Then, remove the cap screw and hex nut (keys 18 and 19), and remove the lever (key 27)
from the housing.
10. Rotate the handwheel (if one is used) counter-clockwise until the handwheel is not compressing the spring
(key 11).
WARNING
To avoid personal injury from precompressed spring force suddenly thrusting the upper diaphragm casing (key 1) away
from the actuator, relieve 1052 spring compression, or carefully remove 1051 casing cap screws by following the
instructions presented in the next two steps before proceeding further.
11. To relieve 1052 spring compression, insert a round rod into one of the slots in the lower bearing seat (key 73). Slot
diameter is 9.5 mm (3/8 inch) for size 40 actuators, 15.9 mm (5/8 inch) for size 60 actuators, and 19.1 mm (3/4
inch) for size 70 actuators. Use the rod to rotate the lower bearing seat, and move it away from the actuator
casings. Continue rotating the lower bearing seat until spring compression is completely removed.
12. Loosen, but do not remove, all casing cap screws (key 5). Make sure there is no spring force on the 1051 upper
diaphragm casing. Unscrew and remove the cap screws and hex nuts (keys 5 and 6), and then remove the upper
diaphragm casing and the diaphragm (key 3).
13. Proceed as appropriate:
For 1051 actuators,
a. Read and follow the warning printed on the nameplate (key 56) located on the diaphragm plate (key 4).
17
1051 and 1052 H & J Actuators
October 2012
Instruction Manual
D100320X012
b. Pull the diaphragm plate (key 4) and attached parts out of the actuator. The spring (key 11), diaphragm rod (key
10), cap screw (key 9), spring seat (key 13), hex nut (key 58), turnbuckle (key 57), hex nut (key 16), and rod end
bearing (key 17) will be attached to the diaphragm head.
WARNING
For 1051 actuators, the diaphragm plate (key 4) may be wedged against the diaphragm rod (key 10), thereby preventing
the spring compression from being relieved as the cap screw (key 9) is loosened. Dislodge the diaphragm head from the
diaphragm rod by loosening the cap screw (key 9) one full turn and tapping the underside of the diaphragm head until it
follows the cap screw disassembly. Failure to check for this situation before removing the cap screw (key 9) could cause
personal injury due to the sudden release of spring compression as the cap screw is disengaged.
c. Slowly remove the cap screw (key 9) while making sure that the diaphragm head is following the cap screw
removal. Note that spring load will be zero before the cap screw is completely removed. Then separate the
remaining parts of the assembly.
For 1052 actuators,
a. Remove the rod end bearing (key 17), the hex nut (key 16), the turnbuckle (key 57), and the hex nut (key 58)
from the diaphragm rod (key 10).
b. Pull the diaphragm plate (key 4) and attached parts out of the actuator. Then remove the cap screw (key 9) to
separate the diaphragm plate and the diaphragm rod.
c. Proceed as appropriate:
D For actuator designs without a set screw in the spring barrel (key 12), remove the actuator spring (key 11) from the
actuator. If it is necessary to remove the adjustor (key 74) from the spring barrel during this procedure, heat the
base of the adjustor to 177_C (350_F) long enough for the thread locking adhesive (high strength) (key 77) to lose
its holding strength. Then, unscrew the adjustor from the spring barrel. If the spring seat and the lower bearing seat
(key 13 and 73) are to be replaced, unscrew the lower bearing seat from the adjustor, and then remove the thrust
bearing and the bearing races (keys 71 and 72) from the lower bearing seat.
D For actuator designs with a set screw, (key 75), remove the actuator spring (key 11) from the actuator. If the spring
seat and the lower bearing seat (keys 13 and 73) are to be replaced, unscrew the lower bearing seat from the
adjustor, and then remove the thrust bearing and the bearing races (keys 71 and 72) from the lower bearing seat. If
it is necessary to remove the spring adjustment parts, heat the set screw (key 75) to 177_C (350_F) long enough for
the thread-locking adhesive (high strength) (key 77) to lose its holding strength, and then loosen the set screw (key
75). Unscrew the spring adjustor (key 74) from the spring barrel (key 12).
Assembly
This procedure assumes that the actuator is completely disassembled. If the actuator is not completely disassembled,
start these instructions at the appropriate step. Key numbers used are shown in figure 12 for 1051 actuators and in
figure 13 for 1052 actuators.
1. If the 1052 spring barrel (key 12) was removed from the housing (key 10), align the spring barrel to the housing as
described below to ensure that the offset hole in the base of the spring barrel is located properly.
For size 40 and 60 actuators, note that one of the accessory mounting bosses on the spring barrel is closer to the
diaphragm end of the spring barrel. Place the spring barrel on the housing with the upper boss (the one closer to the
diaphragm end) on the same side as the boss located on the housing (see figure 13). This ensures proper positioning of
the offset hole. Secure the spring barrel with the cap screws (key 21).

For size 70 actuators, the spring barrel need not be aligned in any particular position when placing it on the housing.
Note
Refer to table 11 for bolting torques for actuator bolts and cap screws. Exceeding any torque requirement may impair the safe
operation of the actuator.
2. Proceed as appropriate:
For 1051 actuators,
a. Coat the thread of the cap screw (key 9) and the tapered end of the diaphragm rod (key 10) with lithium grease
(key 76).
b. Assemble the diaphragm rod, spring seat (key 13), spring (key 11), and diaphragm plate (key 4), and secure with
the cap screw (key 9). Tightening the cap screw will compress the spring. Be certain the tapered end of the
diaphragm rod is seated in the corresponding hole in the diaphragm plate, that the spring is seated in the spring
seat, and that the cap screw is tightened to the torque specified in table 11.
c. Install the hex nut (key 58), turnbuckle (key 57), hex nut (key 16), and rod end bearing (key 17) onto the
diaphragm rod.
d. Be certain the travel stops (key 8) are located as shown in figure 11.
e. Install the diaphragm plate and attached parts into the actuator.
f. Be sure the warning nameplate (key 56) is in place. Install the diaphragm (key 3) and the upper diaphragm casing
(key 1). Install the cap screws and hex nuts (keys 5 and 6). Tighten the cap screws evenly in a crisscross pattern to
compress the spring and secure the upper diaphragm casing. Tighten these cap screws to the torques shown in
table 11.
For 1052 actuators,
a. Proceed as appropriate:
D For actuator designs without a set screw in the spring barrel (key 12), if the adjustor and attached parts were
removed, first clean and then lubricate the upper threads of the adjustor (key 74) with lithium grease (key 76) as
shown in figure 13. Install the lower bearing seat (key 73), the thrust bearing (key 71), the thrust bearing races (key
72), and the spring seat (key 13) onto the adjustor. Then, first clean and then coat the lower end of the adjustor
with thread-locking adhesive (high strength) (key 77) as shown in figure 13, and install the entire assembly into the
spring barrel (key 12). Let the adjustor stand undisturbed for at least two hours after installation to allow the
thread-locking compound to cure.
CAUTION
When applying lubricant to the upper threads and thread-locking compound to the lower threads of the adjustor, do not
overlap the coat of lubricant with the coat of thread-locking compound since this will adversely affect the performance
quality of both substances.
D For actuator designs with a set screw, (key 75), if the adjustor (key 74) and attached parts were removed, lubricate
the threads of the adjustor with lithium grease (key 76). Install the lower bearing seat (key 73), the thrust bearing

the spring barrel (key 12). After first cleaning and then coating the set screw (key 75) with thread-locking adhesive
(high strength) (key 77), secure the adjustor with the set screw (key 75).
b. Coat the tapered end of the diaphragm rod (key 10) and the threads of the cap screw (key 9) with lithium grease
(key 76). Bolt the diaphragm plate (key 4) to the diaphragm rod with the cap screw (key 9). Tighten the cap
screw to the torque value listed in table 11.
c. Be certain the travel stops (key 8) are located as shown in figure 11.
d. Install the spring (key 11) into the spring barrel. Install the diaphragm plate and diaphragm rod into the actuator.
Attach the hex nut (key 58), turnbuckle (key 57), hex nut (key 16), and rod end bearing (key 17) to the
diaphragm rod.
e. Install the diaphragm (key 3).
f. Place the upper diaphragm casing (key 1) on the lower diaphragm casing (key 2). If necessary, rotate the lower
bearing seat (key 73) so that the upper diaphragm casing travel stop will not contact the diaphragm when the
casing cap screws (key 5) are tightened. Secure the upper diaphragm casing with the cap screws and hex nuts
(keys 5 and 6) in a criss-cross pattern to the torques shown in table 11. Be sure the warning nameplate is in place
on the casing.
3. If the bearing (key 67) was removed, press in the new bearing. The end of the bearing should be flush with the
outside of the mounting bracket or mounting plate (key 22).
4. For an actuator with an H mounting adaptation, install the output shaft (key 87) through the mounting plate (key
22) and secure it with the retaining ring (key 88). Then, attach the mounting plate and output shaft assembly to the
actuator housing (key 20) with the cap screws (key 23). Tighten the cap screws to the appropriate torque value
listed in table 11.
5. For an actuator with a J mounting adaptation, refer to figures 12 and 13. Install the output shaft (key 87) with
attached coupling (key 90) through the mounting bracket (key 22) and secure it with the retaining ring (key 88).
Attach the mounting bracket and output shaft assembly to the actuator housing (key 20) with the cap screws (key
23). Tighten the cap screws to the appropriate torque value listed in table 11.
6. For an actuator with a J mounting adaptation and a 50.8 mm (2-inch) output shaft, refer to figure 14. Install the
output shaft (key 87) with attached coupling (key 90) through the mounting plate (key 22) and secure it with the
retaining ring (key 88). Attach the mounting plate and output shaft assembly to the actuator housing with the cap
screws (key 23). Tighten the cap screws to the appropriate torque value listed in table 11.
7. Apply lithium grease (key 76) to the output shaft splines. Then, align the lever (key 27) and output shaft so that the
marking that was made in step 6 or 7 of the Disassembly procedure is oriented correctly. Slide the lever into place.
When installing the lever, align the bolt holes in the lever as close as possible with the hole in the rod end bearing
(key 17). 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.
8. Clamp the lever to the output shaft with the cap screw (key 28). Tighten the cap screw to the torque value listed in
table 11.
9. For 1052 actuators, complete the Initial Compression portion of the Adjustment section before proceeding.
10. Rotate the lever (key 27) to align with the rod end bearing (key 17). This connection can be aided by stroking the
actuator off its up travel stop with a regulated air source.

Changing Actuator Mounting
The actuator is normally positioned vertically in a horizontal pipeline. However, each style can be mounted in two
possible mounting styles and four possible positions (see figure 10 ).
Note
Due to its weight, the 1052, size 70 actuator must be externally supported if mounted in the horizontal position.
WARNING
Before performing any Actuator Mounting steps, follow the steps in the WARNING at the beginning of the Maintenance
section.
Use the following procedures along with figures 12 and 13 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 (keys 34 and 63), and remove the cover (key 33).
2. Heat the hex nut (key 19) to 177_C (350_F) long enough for the thread-locking adhesive (high strength) (key 77) to
lose its holding strength. Then, remove the cap screw and hex nut (keys 18 and 19).
3. Loosen the cap screw (key 28).
CAUTION
If necessary, use a wheel puller to remove the lever (key 27) from the output shaft (key 87). 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 27) that is nearest to the end of the output shaft (key 87). 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 23), and remove the actuator housing (key 20) from the mounting bracket (key 22).
b. Rotate the actuator housing 180 degrees, maintaining the appropriate position (1, 2, 3, or 4), and place the
actuator onto the mounting bracket (key 22).
c. Secure the actuator housing to the mounting bracket with the cap screws (key 23). Tighten the cap screws to the

b. Unscrew the cap screws (key 23) and remove the mounting plate (key 22) and output shaft (key 87) assembly
from the actuator housing. Remount the assembly on the opposite side of the actuator, and secure it to the
housing with the cap screws (key 23). Tighten the cap screws to the torque value listed in table 11.
c. Rotate the actuator housing 180 degrees, maintaining the appropriate position (1, 2, 3, or 4) and secure the
actuator housing to the mounting bracket with the cap screws (key 78). Tighten the cap screws to the torque
value listed in table 4.
7. Install the lever (key 27) 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 87) 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 17).
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 28). Tighten the cap screw to the torque value listed in table 11.
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 (high strength) (key 77) to the threads of the cap screw (key 18).
9. Connect the lever (key 27) and the rod end bearing (key 17) with the cap screw and hex nut (keys 18 and 19). 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 11.
10. Note the position of the valve body or other operated equipment and direction of rotation. Position the travel
indicator (key 37) accordingly. Replace the cover (key 33), and secure it with the cap screws and washers (keys 34
and 63). If the holes in the cover and housing (key 20) 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 23), 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 11.
11. Follow the instructions in the Turnbuckle Adjustment section.
Changing Positions
1. Unscrew the cap screws and washers (keys 34 and 63), and remove the cover (key 33).
2. Mark the orientation of the lever (key 27) with respect to the output shaft (key 87). This marking is used during
reassembly to allow for proper lever/output shaft positioning. When the lever and output shaft are properly
marked, heat the hex nut (key 19) to 177_C (350_F) long enough for the thread-locking adhesive (high strength)
(key 77) to lose its holding strength. Then, remove the cap screw and hex nut (keys 18 and 19).
CAUTION
If necessary, use a wheel puller to remove the lever (key 27) from the output shaft (key 87). You may tap the wheel puller
screw lightly to loosen the lever, but hitting the screw with excessive force could damage the operated equipment.

Top-Mounted Handwheels and Adjustable Travel Stops
Handwheel and Travel Stop Operation
Note
If repeated or daily manual operation is expected or desired, the unit should be equipped with a manual handwheel actuator. Refer
to the separate manual handwheel actuator instruction manual for mounting instructions.
The top-mounted handwheel assembly is attached to a special upper diaphragm casing (key 1, figures 12 and 13) with
cap screws (key 141, figure 15). A hex nut (key 137, figure 15) locks the handwheel in position.
Turning the handwheel (key 51, figure 15) clockwise into the upper diaphragm casing forces the pusher (key 135,
figure 15) against the diaphragm and diaphragm plate (keys 3 and 4, figures 12 and 13) to compress the spring (key
11, figures 12 and 13) and move the diaphragm rod downward. Turning the handwheel counterclockwise allows the
actuator spring to move the diaphragm rod upward. If the action is push-down-to-close, full opening can be restricted
by positioning the handwheel at the desired position. If the action is push-down-to-open, full closing can be restricted
by use of the handwheel.

Instruction Manual
D100320X012
The adjustable up travel stop (figure 16) limits the actuator stroke in the upward direction. To make adjustments, first
relieve actuator loading pressure before removing the closing cap (key 187) as it is a pressure retaining part. Also, for
size 70 actuators, the hex nut (key 137) must be loosened.
Turning the stem (key 133) clockwise into the diaphragm case moves the actuator stem downward or
counterclockwise to allow the spring to move the actuator stem upward. If the action is push-down-to-close, full
opening can be restricted; or if the action is push-down-to-open, full closing can be restricted by the position of the
adjustable travel stop.
The adjustable down travel stop (figure 17) limits the actuator stroke in the downward direction. To make
adjustments, first relieve actuator loading pressure before removing the closing cap (key 187) as it is a pressure
retaining part. After removing the closing cap, loosen the hex jam nut (key 189) and either turn the hex nut (key 63 for
size 40, and 70 actuators; or key 54 for size 60 actuators) down on the stem (key 133) to limit travel, or up on the stem
to allow more travel. Lock the jam nut against the hex nut and replace the closing cap after the adjustment has been
made. For size 70, tighten the hex nut and replace the closing cap after adjustment.
Handwheel and Travel Stop Maintenance
WARNING
Avoid personal injury or property damage from sudden release of process pressure or uncontrolled movement of parts.
Before performing any maintenance operations:
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.
If loading pressure seems to be leaking from either the handwheel or adjustable up stop, the O-rings (key 138 and 139,
figures 15 and 16) may need replacement. If the adjustable down stop leaks, the O-ring (key 139, figure 17) may need
replacement or possibly the closing cap (key 187, figure 17) is not tight. To tighten the closing cap, apply a good grade
of thread sealant to the closing cap threads.
For ease of operation, the stem (key 133, figures 15, 16, and 17) threads may need an occasional application of lithium
grease. A grease fitting (key 169, figures 15 and 16) is provided for this purpose in the size 70. The size 70 may also
need to have the thrust bearing (key 175, figures 15 and 16) packed with lithium grease. Travel stops for the smaller
casings can be lubricated between the stem and pusher (key 135, figures 15 and 16) with lithium grease.
1. Bypass the control valve, reduce loading pressure to atmospheric, and remove the tubing or pipe from the body
(key 142, figures 15, 16, and 17).

WARNING
To avoid personal injury from the precompressed spring force thrusting the upper diaphragm casing (key 1, figures 12 and
13) away from the actuator, either relieve 1052 spring compression, or carefully remove 1051 casing cap screws by
following the instructions that are referenced in the steps below before removing the casing.
2. Relieve all actuator spring compression by following the procedures presented in the Disassembly portion of the
Maintenance section. Then, rotate either the handwheel (key 51, figure 15) or the travel stop stem (key 133, figures
16 and 17) counterclockwise until the handwheel or travel stop assembly is no longer compressing the spring.
3. Proceed as appropriate:
For Top-Mounted Handwheels and Adjustable Up Travel Stops
a. Remove the upper diaphragm casing (key 1, figures 12 and 13) by following steps 1, 3, 6, 7, 9, 11, and 12 of the
Disassembly portion of the Maintenance section.
b. Remove the cap screws (key 141, figures 15 and 16, and separate the assembly from the upper casing.
c. Loosen the locknut (key 137, figure 15) or remove the closing cap (key 187, figure 16).
d. Turn the stem (key 133, figures 15 and 16) clockwise out of the body. On handwheel assemblies, the cotter pen
and slotted nut (keys 247 and 54, figure 15) will have to be removed so that the handwheel (key 51, figure 15)
and locknut can be taken off the stem first.
e. Remove and inspect the O-rings (keys 138 and 139, figures 15 and 16); replace them if necessary.
f. To complete disassembly for sizes 40 and 60, drive out the groove pin (key 140, figures 15 and 16), and slide the
pusher (key 135, figures 15 and 16) off the stem. The pusher of a size 70 unit is held to the stem by a retaining
screw (key 174, figures 15 and 16). Removing the retaining screw and pusher exposes the thrust bearing (key
175, figures 15 and 16) for inspection.
For Adjustable Down Travel Stops
Refer to figure 17 for appropriate key numbers unless otherwise stated.
a. Remove the closing cap (key 187), and unscrew the jam nut and hex nut (keys 189 and 63 for sizes 40, and 70
actuators; or keys 189 and 54 for size 60 actuators) off the stem (key 133).
b. Remove the upper diaphragm casing (key 1, figures 12 and 13) and travel stop body (key 142) by following steps
1, 3, 6, 7, 9, 11, and 12 of the Disassembly portion of the Maintenance section.
c. Unscrew cap screws (key 141), and remove the body from the diaphragm case.
d. Check the condition of the O-ring (key 139), and replace it if necessary.
e. Loosen the hex nut (key 54), and then unscrew the travel stop stem (key 133) out of the actuator stem. The
lower diaphragm plate (key 82) can now be removed and the rest of the actuator disassembled.
4. Reassemble by reversing the order of the steps you took to disassemble, being sure to apply lubricant as previously
mentioned and as shown by the lubrication boxes (key 241) in figures 15 and 16. For size 70 handwheels or up
travel stop assemblies, coat the threads of the retaining screws (key 174, figures 15 and 16) with thread-locking
adhesive (high strength) (key 242).
