Use these instructions to mount a FIELDVUEr Type
DVC5010 or DVC6010 digital valve controller on
Fisher Type 657 and 667 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 measures
that must be taken to protect against
process media.

with Side-Mounted Handwheel

Mounting on Size 30-60 Actuators

Refer to figures 1 and 2 for mounting parts
identification. Refer to the FIELDVUE DVC5000
Series Digital Valve Controllers Instruction Manual ­Form 5335 for DVC5010 digital controller parts
identification, and the FIELDVUE DVC6000 Series
Digital Valve Controllers Instruction Manual - Form
5647 for DVC6010 digital valve controller part
identification. Refer to the appropriate actuator
instruction manual for actuator installation,
operation, maintenance and parts identification.

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
actuator, releasing all pressure from the actuator.
Use lock-out procedures to be sure that the above
measures stay in effect while you work on the
equipment.

2. Attach the connector arm (key 108) to the valve
stem as follows:

D On actuators without side-mounted handwheel,

refer to figure 1.

a. Remove one of the stem connector screws.
Insert one of the cap screws (key 120) included in
the kit through the connector arm (key 108) and
start it in the stem connector. Tighten the screw
so that the stem connector clamps the valve and
actuator stems but still permits the connector arm
to be moved.

b. Remove the second stem connector screw.
Swing the connector arm into place and start the
second screw (key 120) from the kit. Tighten both
screws.

D On actuators with side-mounted handwheel
refer to figure 2. Loosen the lock nut below the travel
disc. Insert the connector arm beneath the travel
disc and tighten the lower lock nut against the
connector arm.
