1052 Actuator
D104082X012
Fisherr 1052 Size 70 Diaphragm Rotary
Actuator
Fisher 1052 size 70 spring‐return diaphragm rotary
actuators operate splined shaft rotary valves, such as
8580, 8532, 8590, CV500, V500, and Vee‐Ballt
(V150, V200 and V300) valves. 1052 actuators are
suitable for on‐off service or for throttling service.
This actuator is designed for easy installation of a
broad range of options: limit switches, position
indicating switches, positioners, and manual
over‐rides. Option applicability varies with actuator
size. Refer to the specifications table and table 4 for
information concerning option applicability and
specifications.

Features
n Application Flexibility-- 1052 rotary actuators are
available with fail‐open or fail‐close construction
and can be mounted in any of four actuator‐valve
mounting positions. See figure 5 for mounting
positions. These actuators can be mounted on a
broad range of Fisher valves or used with other
equipment.
n Minimal Dead Band-- Single joint linkage with
splined and clamped lever minimizes lost motion
and improves control accuracy.
n Long Service Life-- Rugged construction provides
stability, corrosion resistance, and protection from
deformation should over‐pressurization occur.
W8508-3
Typical Fisher 1052 Actuator with Vee‐Ball Valve and
FIELDVUE™ DVC6200 Digital Valve Controller
n Safety-- The 1052 actuator has an externally
accessible spring adjuster to relieve spring
compression (see figure 1). Actuator‐valve linkage
is completely enclosed, yet the valve packing
adjustment remains accessible without removing
any parts (see figure 2).

exceeded.
2. Actual actuator torque available depends on specific construction and casing pressure. For information on torque requirements of the valve being considered, contact your Emerson Process
Management sales office.
3. Nitrile O‐rings are used in the optional top‐mounted handwheel and in the optional up and down travel stop assemblies.
4. For higher temperature ratings, contact your Emerson Process Management sales office.
5. This maximum casing pressure is not to be used for normal operating pressure. Its purpose is to allow for typical regulator supply settings and/or relief valve tolerances.

Positioner: For precise positioning of the valve disk or
ball, the actuator should be equipped with a
positioner. Under some service conditions, the 1052
actuator may be used successfully in these
applications without a positioner. For additional
information, contact your Emerson Process
Management sales office with complete service
conditions.
Adjustable Down‐Travel Stop: Used to limit the
actuator stroke in the downward direction
(see figure 3).
Adjustable Up‐Travel Stop: Used to limit the actuator
stroke in the upward direction (see figure 3).
Actuator Locking Mechanism: An actuator locking
mechanism is available. It can be used to keep the
actuator in a locked position (the same as the
spring‐fail position) during maintenance. The padlock
is customer supplied, and the mechanism requires a
modified actuator housing.
Pipe Away Vent: Some applications use natural gas or
other hazardous gases as a supply pressure to the
actuator. These applications sometimes require the
actuator housing to be vented, reducing the
accumulation of gases. For new constructions and
retrofit kit information, contact your Emerson Process
Management sales office with complete service
conditions.

Installation
The actuator is normally positioned vertically in a
horizontal pipeline. Four mounting styles and four
positions for each style are possible (see figure 5). Due
to its weight, the 1052 size 70 actuator must be
externally supported if mounted in the horizontal
position.
When looking in the direction of flow in the pipeline,
an actuator is right‐hand mounted when it is on the
right side of the pipeline, and an actuator is left‐hand
V
mounted when it is mounted on the left side of the
pipeline.
By Emerson Process Management definition, forward
flow is into the face side of the disk or ball, and reverse
flow is into the hub side of the disk or ball.
Dimensions for both actuator types are shown in figure
6. These dimensions should be used in conjunction
with the mounting positions shown in figure 5. Make
clearance considerations before mounting the
actuator to determine the most suitable mounting
position.

Adjustable travel stops (in addition to those shown in
figure 3) are available as discussed below.
As used here, down or downward means in a direction
toward the valve shaft and away from the piston and
diaphragm.
An adjustable down travel stop is installed in a special
actuator housing. The assembly consists of a special
housing, cap screw, locknut, lever, and rod end
bearing. The cap screw can be positioned to limit
downward travel of the actuator lever to any rotation
between 0 and 90 degrees.
The locking mechanism shown in figure 7 is not to be
used as a travel stop. Please specify an adjustable
travel stop assembly instead.
