Use these instructions to mount a FIELDVUEr Type
DVC5020 or DVC6020 digital valve controller on
Fisher Type 1051 and 1052 actuators.

WARNING

Avoid personal injury or property
damage from sudden release of
process pressure or bursting of parts.
Before performing any maintenance
operations:

D Always wear protective clothing

and eyewear.

D Disconnect any operating lines
providing air pressure, electric power,
or a control signal to the actuator. Be
sure the actuator cannot suddenly
open or close the valve.

D Use bypass valves or completely
shut off the process to isolate the
valve from process pressure. Relieve
process pressure from both sides of
the valve. Drain the process media
from both sides of the valve.

D Vent the pneumatic actuator
loading pressure and relieve any
actuator spring precompression.

D Use lock-out procedures to be
sure that the above measures stay in
effect while you work on the
equipment.

D Check with your process or safety
engineer for any additional safety
measures that must be taken to
protect against process media.

1. Isolate the control valve from the process line
pressure, release pressure from both sides of the
valve body, and drain the process media from both
sides of the valve. Shut off all pressure lines to the
pneumatic actuator, releasing all pressure from the
actuator. Use lock-out procedures to be sure that the

the appropriate actuator instruction
manual.

4. See figure 3. For actuator mounting styles A and

mounting styles B and C, continue with step 5.

5. Disconnect the actuator turnbuckle from the lever

2. Mark the positions of the travel indicator and
actuator cover. Then, remove the actuator travel
indicator machine screws, travel indicator, and
actuator cover cap screws.

3. Remove the cover plate from the actuator
housing.

Do not change the position of the rod
end bearing on the end of the
turnbuckle.

6. Loosen the lever clamping bolt in the lever.

7. Mark the lever/valve shaft orientation, and
remove the lever.

Note

Refer to the appropriate actuator
instruction manual to determine the
distance required between the housing
face and the lever face and to
determine the proper tightening torque
for the lever clamping bolt.

11. Connect the turnbuckle and the lever arm.

12. For Type 1051 size 33 and 1052 size 20 and
33 actuators, attach an adaptor (key 117) to the
actuator with four screws (key 116). Then attach the
digital valve controller assembly to the adaptor. The
roller on the digital valve controller feedback arm will
contact the actuator cam as it is being attached.
Install and tighten four screws (key 116).

For other size 1051 and 1052 actuators, attach the
digital valve controller assembly to the front access
opening of the actuator. The roller on the digital
valve controller feedback arm will contact the
actuator cam as it is being attached. Install and
tighten four screws (key 116).

13. Replace the actuator cover and the travel
indicator in the positions that were marked in step 2.

CAUTION

To avoid parts damage, do not
completely stroke the actuator while
the cover is removed.

WARNING

To avoid personal injury from moving
parts, keep fingers and tools clear
while stroking the actuator with the
cover removed.

For additional information concerning mounting,
setup, calibration and maintenance, refer to the
FIELDVUE DVC5000 Series Digital Valve
Controllers Instruction Manual - Form 5335 for
DVC5010 digital controllers, and the FIELDVUE
DVC6000 Series Digital Valve Controllers Instruction
Manual - Form 5647 for DVC6010 digital valve
controllers.

Note

Actuator cover alignment on the Type
1052 actuator can be aided by moving
the actuator slightly away from its up
travel stop using a regulated air
source. If hole alignment cannot be
obtained in this manner, temporarily
loosen the cap screws that secure the
