Integrated Digital Technology
A typical GX configuration features the FIELDVUE
DVC2000 digital valve controller. The industry-
leading FIELDVUE digital valve controller brings easier
control, enhanced performance and unduplicated
maintenance advantages to control valve
applications.
In fact, FIELDVUE instruments provide
much more than traditional valve
positioning. They are core components
of Emerson’s PlantWeb
™
digital plant
architecture.
As such, they present critical operating information
about themselves and the process to enable plant
personnel to make better-informed decisions.
The PlantWeb digital plant architecture offers
proven improvements in system availability, reduced
variability, increased throughput and enhanced
product quality.

Easy to Maintain
The GX is robust and compact. Its design architecture features common
parts across all sizes, which reduces spare parts inventory requirements
and associated costs.
Actuator removal is quick and easy. The actuator can be easily field
reversed to a fail-open or fail-closed configuration.
The digital GX with integrated DVC2000 features linkage-less,
non-contact position feedback, which eliminates mechanical wear
between the valve and instrument. The digital GX features an integral
interface to eliminate tubing for most applications, further simplifying
maintenance issues found in most control valve assemblies today.
The one-piece packing follower threads into the bonnet to simplify
installation and adjustment of the packing system. The system employs
live-loading to compensate for normal wear.
