Identification

The EL-O-Matic F-Series Rack and Pinion actuators are available as double-acting or spring-
return versions. 13 models are available, ranging from 12 Nm to 4000 Nm (106 to 35000
lbf.in) nominal torque output.
The EL-O-Matic F-Series uses standardized interfaces for solenoid, switchbox or positioner
mounting (VDI/VDE3845; NAMUR). The valve interface is equipped with an insert in the
pinion bottom that allows both ISO5211 or DIN3337 mounting.
The springs in the spring-return version allow a fail action in case of loss of air supply
pressure (Fail-to-Close or Fail-to-Open).
As from size FD150 double-acting versions have flat end caps to reduce actuator length
and internal air volume.
