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.

Consult the separate positioner instruction manual for actuator principle of operation with positioner.
Specifications
Specifications are shown in table 1. Specifications for actuator operation, as it originally comes from the factory, are
stamped on the nameplate attached to the actuator.
Installation
When an actuator and valve body are shipped together, the actuator is normally mounted on the valve. Follow the
valve body instructions when installing the control valve in the pipeline, and then perform the procedures presented in
the Loading Connection section. 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
Always wear protective gloves, clothing, and eyewear when performing any installation operations to avoid personal
injury. Be aware of pinching parts during installation, maintenance, and adjustments of valve/actuator components.
To avoid personal injury or property damage resulting from the sudden release of pressure, do not install the valve
assembly where service conditions could exceed the limits given on the valve and actuator nameplates. Use
pressure‐relieving devices as required by accepted industry, local, state, or federal codes, and good engineering practices.
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.

W100063
Lifting Valve/Actuator Assembly
To lift the assembly, insert 3/4-10 eyebolts into the two tapped holes on the top of the valve body. These two tapped
holes will carry most of the weight, but the assembly must be balanced using a strap on the 1052PSV casing as shown
in figure 4. The ends of the strap will be positioned underneath two L-shaped flanges or through eyebolts. Figure 4
shows L-shaped flanges attached to the casings. An alternative casing lift method is to use 3/8 inch eyebolts
positioned 180 degrees apart. Use protective pads between the strap and the casing to help prevent damage to the
painted surface. Torque the 3/8-24 cap screws or eyebolts and nuts to 20 lbf•-ft. The assembly can now be lifted using
a hoist capable of leveling these lifting points.
Lifting Valve Only
To lift the valve, insert 3/4-10 eyebolts into the two tapped holes on the top of the valve body. These two tapped holes
will carry most of the weight, but the assembly must be balanced using a strap underneath the valve bottom flange
(key 5 in the SS-84PSV4 instruction manual, D103416X012
using a hoist capable of leveling the 3 lifting points.
), as shown in figure 4. The assembly can now be lifted

Lifting Actuator Only
The actuator with accessories shall be lifted by the casing flange as shown in figure 4. Figure 4 shows L-shaped flanges
attached to the casings. An alternative casing lift method is to use 3/8 inch eyebolts positioned 180 degrees apart. Use
protective pads between the strap and the casing to help prevent damage to the painted surface. Torque the 3/8-24
cap screws or eyebolts and nuts to 20 lbf•ft. A single hoist lift point on the strap will balance and lift the actuator in a
level manner.
Conduit Connection
Diagnostic test fittings are Swagelok tee fittings with 1/4 inch Swagelok QC-series quick connects and appropriate
body protectors installed. Refer to the Bill of Material drawing for locations of diagnostic fittings.
The supply regulator for this assembly requires a 3/4 NPT pipe connection. Use a 3/4 NPT pipe run from the outlet of
the supply regulator to the actuator assembly.
Figure 5. Lever Operating Clearance
See appropriate accessory instruction manuals for additional conduit connections.
Valve Flow Direction
Valve construction can change the flow direction for a control valve assembly. It is important to observe the flow
direction in all valve applications before installing the valve in the pipeline (see figure 3). Refer to the appropriate valve
bulletin or instruction manual.
Note
Observe all warnings and cautions provided in the appropriate valve instruction manual Installation section.
