For Even Greater Versatility,
FIELDVUE Digital Valve Controllers —
Capabilities That Extend Beyond
Traditional Valve Control
While a traditional valve positioner serves a single
purpose, which is to maintain a valve in its intended
control position, FIELDVUE digital valve controllers
(see ) provide much more.
FIELDVUE instrumentation collects
real-time data about valve performance,
which proves crucial not only to reducing
process variability but also to enhancing
plant operations.

run your operation more
efficiently, safely, and profitably by
delivering new insights on valve health.

Choose the Actuator and Accessories to Fit the Control Situation
A choice of Fisher pneumatically operated rotary
actuators makes it easy to specify the right Vee-Ball
control valve package for each application. The rotary
actuators, available in spring-and-diaphragm and piston
styles, share design and construction features that
enable efficient and stable valve operation, even under
application extremes.
•
All actuator/positioner/valve linkages are enclosed for
both personnel safety and protection against damage.
•
Actuator housings are rugged to meet repeated, high-
torque requirements.
•
Splined-and-clamped valve shaft lever, plus a single-
point actuator rod connection, minimize lost motion
for maximum throttling control accuracy.
•
A selection of actuator sizes allows matching actuator
output to operating torque requirements.
•
Corrosion-resistant powder coat paint and corrosion-
resistant fasteners are standard.
•
Optional declutchable manual operators (see ) will
override the actuator to position the valve.
