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
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.
A top-mounted handwheel option is available for infrequent service as a manual actuator. For repeated or daily manual
operation, the unit should be equipped with a side-mounted declutchable 1078 manual actuator. Externally adjustable
travel stops are used to limit the degree of rotation at both ends of the actuator stroke.
The lever for the 2052 actuator is supported by bushings. The lever may be changed to accommodate valve bodies
with different size valve shafts.
