NOTE:
THRUSTS IN THOUSANDS OF POUNDS (IN THOUSANDS OF NEWTONS)
FOR ACTUATORS WITH POSITIONERS
MAY BE INCREASED BY 10% FOR ACTUATORS WITHOUT POSITIONERS.
EITHER THIS THRUST, OR THE MAXUMUM ALLOWABLE LOADING FOR THE CONTROL
DEVICE IS THE LIMITING FACTOR FOR USABLE ACTUATOR FORCE.

Actuator Configurations
480: Yokeless piston actuator with positioner.
481: Yokeless piston actuator without positioner. Other actuators may be obtained without positioner by adding -1 to
the type number.
The above actuators come with standard mounting flange, 105 mm (4.125 inch) maximum rated travel, and threaded
piston rod connection with sizes 30 through 60 for mounting on ball valves, louvers, and dampers with brackets.
These actuators may be obtained with the following alternate universal mounting flange constructions:
-15 Added to Type Number: Allows butterfly valve mounting for a standard actuator with 105 mm (4.125 inch)
maximum travel and threaded piston rod connection, and comes in sizes 30 through 60.
-16 Added to Type Number: Provides 206 mm (8.125 inch) maximum travel and threaded piston rod connection, and
comes in sizes 40 through 60.
