DVC6025 Remote Feedback Unit on Long-Stroke [102-610 mm (4-24 inch) Travel]
Sliding‐Stem Actuators and Rotary Actuators
Note
If ordered as part of a control valve assembly, the factory mounts the DVC6025 remote feedback unit on the actuator. If you
purchased the remote feedback unit separately, you will need a mounting kit to mount the remote feedback unit on the actuator.
See the instructions that come with the mounting kit for detailed information on mounting the remote feedback unit to a specific
actuator model.
DVC6025 remote feedback units use a cam and roller as the feedback mechanism. Figure 6 shows an example of
mounting on sliding‐stem actuators with travels from 4 inches to 24 inches. Some long‐stroke applications will require
an actuator with a tapped lower yoke boss. Figures 7 and 8 show examples of mounting on rotary actuators.

As shown in figure 7, two feedback arms are available for the remote feedback unit. Most long‐stroke sliding‐stem and
rotary actuator installations use the long feedback arm [62 mm (2.45 inches) from roller to pivot point]. Installations
on 1051 size 33 and 1052 size 20 and 33 actuators use the short feedback arm [54 mm (2.13 inches) from roller to
pivot point]. Make sure the correct feedback arm is installed on the remote feedback unit before beginning the
mounting procedure.
