Introduction
Scope of Manual
This instruction manual includes installation, adjustment, operation, maintenance, and parts information for the
Fisher 2052 diaphragm rotary actuator (figure 1). Instructions for the control valve, positioner, manual actuator, and
other accessories are included in separate manuals.
Do not install, operate, or maintain a 2052 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.
Description
2052 spring-and-diaphragm rotary actuators are used on rotary-shaft valve bodies for throttling or on-off applications.
The 2052 may be used for on-off service without a positioner, or it may be used for throttling service with a positioner,
depending on service conditions. The 2052 has an ISO 5211 mating interface that allows installation to non-Fisher
valves. Refer to separate bulletins for valve and positioner information.
