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-Ball
t
, 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.
Do not install, operate, or maintain a 1052PSV actuator without being fully trained and qualified in valve, actuator, and
accessory installation, operation, and maintenance. To avoid personal injury or property damage, it is important to
carefully read, understand, and follow all the contents of this manual, including all safety cautions and warnings. If you
have any questions about these instructions, contact your Emerson Process Management sales office before
proceeding.
