Introduction
Scope of Manual
This instruction manual includes installation, adjustment, maintenance, and parts ordering information for the Fisher
1052PSV (Size 60) pneumatic spring-and-diaphragm rotary actuator (see figure 1).
The seismically qualified actuator design is based on the standard Fisher 1052 size 60 actuator. The 1052PSV size 60
actuator incorporates the tilting diaphragm rod, turnbuckle adjusting feature, upper diaphragm casing assembly, and
SS-129 dual springs mounted within a fabricated box construction. The actuator box is designed for standard 3610J
positioner mounting. Adjustable valve open position is provided by limiting lever rotation with adjustable travel limit
bolts in the bottom of the fabricated actuator box.
To ensure proper assembly, the Vee-Ballt, valve drive shaft, and actuator lever connections are a missing-tooth spline
design, allowing one-way only assembly.
Instructions for the control valve, positioner, and other accessories are covered in separate instruction manuals.

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 with the diaphragm pressure as indicated on the nameplate.

WARNING
Be aware of pinching parts during installation, maintenance, and adjustments of valve/actuator components. To avoid
injury, keep hands and tools clear of actuator access windows when operating or adjusting the actuator.
Precise Valve/Actuator Closed Position and Turnbuckle Adjustment
Correct turnbuckle adjustment ensures that the valve is correctly closed when the actuator is against its travel stops.
Key numbers are shown in figure 13.
A regulated air supply with appropriate gauge will be required to stroke the actuator. The following wrench sizes will
be used to adjust the turnbuckle: 1-5/16 inch wrench for the turnbuckle (key 57), 15/16 inch wrench for the lower
locknut (key 16), and 1-5/16 inch wrench for the left-hand upper locknut (key 58).
Note
For the most accurate adjustment of the actuator, do not remove the cover (key 33) during this procedure.
1. Loosen the lower locknut (key 16).
2. Make sure the actuator box assembly (key 14) 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.

D103407X012
CAUTION
The bolt pattern on the travel indicator scale (key 35) is symmetric, meaning the component could be installed in multiple
orientations. Ensure the travel indicator scale is mounted correctly as shown in figure 10, otherwise there will be false valve
position indication.
WARNING
Be aware of pinching parts during installation, maintenance, and adjustments of valve/actuator components. To avoid
injury, keep hands and tools clear of actuator access windows when operating or adjusting the actuator.
Actuator Spring Adjustment
Initial Setting
The 1052PSV nameplate specifies an initial spring setting. Initial setting 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. (With
the actuator connected to the valve and pressure applied to the valve, a higher pressure will be required to start
actuator travel).
The initial setting was selected (based upon the service conditions specified when the actuator was ordered) so that,
when the actuator and valve are in service, the valve will seat properly and full travel will be obtained within a
diaphragm casing range of 0 to 2.7 bar (0 to 39 psig).
If the actuator has been disassembled or if the spring adjustment was changed, and it is desired to match the initial
setting 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, use the special 2-1/2 inch wrench. Rotate the spring adjustor to move it toward the casing
to increase initial setting or away from the casing to decrease initial setting (keys 1 and 2, figure 13).
1. A regulated air supply with an appropriate gauge will be required to supply air pressure on top of the diaphragm to
stroke the actuator.
2. Rotate the spring adjustor (key 74), with the special 2-1/2 inch hex wrench, GE45169, so that the diaphragm rod
(key 10) just starts to travel at the spring set pressure specified on the nameplate (0.34 bar [7.0 psig] typical).
Note
Perform this setting with the actuator disconnected from the valve. The spring adjustor will need to compress the springs
and 12) approximately 1-7/8 inch for a 0.34 bar (7.0 psig) initial spring set.
(keys 11
Stroking Range
The initial spring setting 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

Instruction Manual
D103407X012
push‐down‐to‐open valve action, the initial spring setting is the maximum allowable to provide the maximum spring
closing force.
The following steps will set the stroking range or valve rotation to 80 degrees. There are two travel stop spacers
located in the casing in case the adjustable stops are not set properly.
1052PSV Actuator
March 2021
CAUTION
Any increase of this setting can over‐stress the spring at full travel and may shorten the fatigue life of the spring.
1. Apply sufficient supply pressure on top of the diaphragm to stroke the valve to 80 degrees (+/- 2 degrees).
2. Apply nuclear grade anti-seize lubricant (key 30) to the two 7/89 x 6.50 cap screws (key 22) and the two 7/89 hex
nuts (key 21), threading the nut as far as possible onto the cap screw.
3. Now thread the cap screws and nuts (keys 22 and 21), including washers (key 39), into the actuator box until each
cap screw just touches the lever (key 27) without torquing. Using a 1-7/16 inch wrench, tighten the nuts (key 21) to
163 NSm (120 lbfSft).

WARNING
Be aware of pinching parts during installation, maintenance, and adjustments of valve/actuator components. To avoid
injury, keep hands and tools clear of actuator access windows when operating or adjusting the actuator.
Loading Connection
Follow these steps if the tubing and fittings have been loosened or removed from the accessories.
1. Connect the loading pressure piping to the pressure connection in the top of the diaphragm casing. Run 3/8 inch
tubing between the 1/4 NPT pressure connection and the instrument. Run 1/2 inch tubing between the volume
booster and the upper casing.
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 valve positioner) is used, be sure that the accessory is properly connected to the
actuator. If a valve positioner is part of the assembly, the pressure connection to the actuator will normally be made
at the factory.
3. When the control valve is completely installed and connected to the instrument, check for correct action
(air‐to‐open) to match the controlling instrument. For successful operation, the actuator stem and valve shaft must
move freely in response to the loading pressure change on the diaphragm.

CAUTION
To avoid parts damage, do not stroke the actuator while cover (key 33) is off.
Disassembly
The following procedure describes how to completely disassemble the actuator. When inspecting and replacing parts,
perform only those steps necessary to accomplish the repair.
Do not, under ordinary circumstances, remove the cap screws (keys 7 and 8) at this time.
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 beyond its fully open or closed position. This could cause
damage to the valve components and/or seal.
1. Perform the steps in the WARNING at the beginning of the Maintenance section to isolate the control valve and
actuator.
2. Remove the tubing or piping from the top of the actuator.
3. Remove the positioner, if used. If necessary, refer to the positioner instruction manual for removal instructions.
4. Unscrew the cap screws (key 34), and remove the washers (key 31), cover (key 33), and any accessories attached to
this end of the actuator.
5. Remove the travel indicator (key 37) from the hub (key 29). Slide the hub (key 29) from the cover.
6. Inspect, and if necessary, replace the cover bushing (key 31). Remove the travel indicator scale (key 35) by
removing the self‐tapping screws (key 36). Press the bushing out of the cover (key 33).
7. Remove the cap screw and hex nut (keys 18 and 19).

CAUTION
When removing the actuator from the valve, do not use a hammer or similar tool to drive the lever (key 27) off the valve
shaft. Driving the lever could damage internal valve parts. On some valve types, driving the lever off the shaft could move
the valve disk or ball and bearings away from the centered position, causing subsequent damage to valve parts as the valve
is operated.
A wheel puller may be used to remove the lever. It is okay to tap the wheel puller screw lightly to loosen the lever, but
hitting the screw with excessive force could also damage valve parts or disrupt the centered position of the valve disk and
bearings.
WARNING
To avoid personal injury from pre‐compressed spring force suddenly thrusting the upper diaphragm casing (key 1) away
from the actuator, relieve 1052PSV spring compression before proceeding further.
9. To relieve spring compression, use the special 2-1/2 inch wrench to rotate the spring adjustor (key 74), and move it
away from the actuator casings. Continue rotating the spring adjustor until spring compression is completely
removed.
10. Unscrew and remove the cap screws, washers, and hex nuts (keys 5, 26, and 6), and then remove the upper
diaphragm casing and the diaphragm (key 3).
11. To remove the diaphragm plate (key 4), remove the rod end bearing (key 17), the lower locknut (key 16),
turnbuckle (key 57), and the left hand threaded upper locknut (key 58) from the diaphragm rod (key 10).

Spare Part Requirement Rationale Shelf Life
Cycled parts will exhibit wear over time. Based on
experience and testing, Emerson recommends
replacing this component every 30 years.
Recommendation to purchase this spare part is
based on shelf life restrictions. The diaphragm is
a key component within the actuator
construction, required to ensure optimal
performance over time. Degradation of the
diaphragm could lead to inconsistencies with
valve operation. Emerson recommends replacing
this component every 6 years.
The bushing will see repeated cycles in contact
with a metal hub. It is the manufacturer's
recommendation to replace the cover/bushing
assembly when wear or diagnostic testing shows
degraded performance or after 30 years of
operation, whichever comes first.
The special wrench is not commercially available.
This wrench is required to adjust actuator spring
load.
