Introduction
Scope of Manual
This instruction manual provides installation, maintenance, and parts information for Fisher 480 Series yokeless piston
actuators.
Do not install, operate, or maintain 480 Series actuators 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
480 Series actuators (figure 1) are yokeless piston actuators that are used in either throttling or on-off applications
with ball valves, butterfly valves, louvers, dampers, and rheostats. They require pneumatic pressure loading from
double-acting positioners (Fisher 3570) or from on-off loading and unloading devices.
Specifications
Table 1 lists specifications for the 480 Series actuator and table 3 lists specifications for the 3570 actuator.
