Technology and Innovation in Process Control
The DVC2000 instrument can be used as a direct replacement for older
analog instruments, or it can be used within a digital environment,
communicating via HART® protocol. Digital communication allows a user
to extract more value from the DVC2000 instrument. Critical
information such as alerts, alarms and diagnostic data can be easily
integrated with the control system to provide a view into the field device
from the safety of the control room.
Designed to meet your needs, the DVC2000 instrument is available with
an integrally mounted position transmitter and two integral limit
switches. The transmitter provides a 4-20mA signal for position
verification, and the switches can be configured to indicate open and
closed positions at any point within the calibrated travel.
The DVC2000 instrument includes diagnostic capabilities that can be
used to monitor control valve condition in order to predict failure.
Diagnostic tests can be performed on-line, with no interruption to the
process, or off-line when the process is shut down or the valve bypassed.
If used on a HART network, the tests can be performed remotely and
scheled to run automatically.
ustomer needs were taken directly to the
drawing board when engineers developed the
DVC2000 Digital Valve Controller. It
incorporates the powerful diagnostic capabilities of
FIELDVUE instruments in an easy-to-use package with
automatic calibration and tuning capabilities.
Pushbutton configuration and a multi language local
interface make the DVC2000 instrument simple to
apply, operate and maintain. At the same time it
provides unrivaled benefits to control valve users.
Simple to Apply
The DVC2000 instrument has been designed in
accordance with global standards. It is compact and
can be mounted to any actuator with NAMUR
mounting capabilities, IEC60534-6-1 and IEC 60534-
6-2. Its high performance, linkage-less travel
feedback system means a rection in the number of
mounting parts and mounting complexity.

• Linkage-less, non-contact position feedback
• Valve diagnostics
• In-service Performance Diagnostics tests
• Autotuner
• Integration via HART
Valve Diagnostics
You can instruct AMS ValveLink
software to run Performance
Diagnostics tests automatically.
When a sweep is complete, the
software will show problems,
possible causes and recommended
actions all while the valve is on-line
and in service.
Mounts Directly to Design GX Valve
When fitted to the Fisher Design GX valve,
the DVC2000 mounts directly to an
interface pad on the actuator yoke leg,
eliminating the need for mounting
brackets. Internal passages route the
pneumatic output to the actuator casing,
eliminating the need for external tubing
(air-to-open configuration only).
Technology and Innovation in Process Control
Simple to Operate
The DVC2000 instrument has a local user interface
that includes a liquid crystal display and four
pushbuttons. The display is protected from the
environment by a NEMA 4X / IP66 enclosure and
supports multiple languages, including German,
French, Italian, Spanish, Chinese, Japanese and
English.
The local interface can be used to initiate a quick
setup routine that calibrates and tunes the
instrument specifically for the actuator on which it
has been installed. This helps provide accurate and
consistent performance.
The DVC2000 instrument is a core
component of Emerson’s PlantWeb®
digital plant architecture. PlantWeb
integrates intelligent field devices and
molar software such as AMS™ Suite:
Intelligent Device Manager or the DeltaV™ digital
automation system. All are linked by the informationrich
HART communication protocol.
The DVC2000 instrument powers PlantWeb by
capturing and delivering critical operating
information about the valve and the process,
enabling plant personnel to make better-informed
decisions leading to increased availability, reced
variability, process optimization, increased
throughput and enhanced proct quality.
Simple to Maintain
The DVC2000 instrument is simple to maintain e to its self-diagnostic
capabilities. Also, the information that it provides, via PlantWeb digital
plant architecture, can be used to simplify the maintenance of the
control valve on which it is installed.
When used in conjunction with AMS ValveLink® software, the
information provided by the DVC2000 instrument can be used to
diagnose faults such as increased friction, incorrect seating or sealing
forces, non-linearities, pneumatic faults or dynamic errors. This
information can be trended to enable failures to be predicted and action
taken prior to an unplanned shutdown.
The DVC2000 instrument features linkage-less position feedback. There
are no touching parts between the instrument and valve stem,
simplifying controller installation and maximizing cycle life. Should
maintenance be required the instrument can be removed from the valve
easily, leaving the position feedback mechanism mounted on the valve.

Local User Interface
With pushbuttons for menu navigation
and a liquid crystal display, the local
user interface allows you to configure
and calibrate the DVC2000 instrument
in any one of seven different languages.
