Introduction
Scope of Manual
This instruction manual includes installation, maintenance, and parts ordering information for Fisher POSI-SEAL
1035/El-O-Matic rack-and-pinion rotary actuators (figure 1). These actuators are available in both double-acting and
spring-return (figure 2) configurations. Spring return units provide fail action in response to spring compression. The
actuator is field reversible. Instructions for the valve and for any accessories used with the actuator are found in
separate manuals.
Do not install, operate, or maintain a 1035 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.
