Fisher™ FIELDVUE™ DVC6200 Digital Valve
Controller
The FIELDVUE DVC6200 digital valve controller is a
HARTr communicating instrument that converts a
two‐wire 4‐20 mA control signal into a pneumatic output
to an actuator. It can easily be retrofitted in place of
existing analog positioners on most Fisher and non‐Fisher
pneumatic actuators.
Features
Reliability
n Linkage‐Less Non‐Contact Position Feedback— The
high performance, linkage‐less feedback system
eliminates physical contact between the valve stem
and the DVC6200. There are no wearing parts so cycle
life is maximized.
n Built to Survive—The field proven DVC6200 instrument
has fully encapsulated electronics that resist the
effects of vibration, temperature, and corrosive
atmospheres. A weather‐tight wiring terminal box
isolates field wiring connections from other areas of
the instrument.
Performance
n Accurate and Responsive— The two‐stage positioner
design provides quick response to large step changes
and precise control for small setpoint changes.
n Travel Control/Pressure Fallback— Valve position
feedback is critical to the operation of a digital valve
controller. The DVC6200 can detect position feedback
problems and automatically revert to I/P transducer
mode to keep the valve operational.
Ease of Use
n Enhanced Safety— The DVC6200 is a HART
communicating device, so information can be
accessed anywhere along the loop. This flexibility can
reduce exposure to hazardous environments and
make it easier to evaluate valves in hard to reach
locations.

FEEDBACK SYSTEM

n Faster Commissioning— HART communications allows
you to quickly commission loops with a variety of
tools, either locally at the valve assembly or remotely.
n Easy Maintenance— The DVC6200 digital valve
controller is modular in design. Critical working
components can be replaced without removing field
wiring or pneumatic tubing.
Value
n Hardware Savings— When installed in an integrated
control system, significant hardware and installation
cost savings can be achieved. Valve accessories such
as limit switches and position transmitters can be
eliminated because this information is available via the
HART communication protocol.
n Increased Uptime— The self‐diagnostic capability of
the DVC6200 digital valve controller provides valve
performance and health evaluation without shutting
down the process or pulling the valve assembly from
the line.
n Improved Maintenance Decisions— Digital
communication provides easy access to the condition
of the valve. Sound process and asset management
decisions can be made by analysis of valve information
through Fisher ValveLinkt software.

Valve Diagnostics
Examples of identifiable issues are:
The DVC6200 digital valve controller provides a broad
and deep portfolio of valve diagnostic capabilities.
Whether the 475 Field Communicator is used to check
for valve alerts and operational status, or ValveLink
software is used for comprehensive diagnostic test and
analysis, the tools are easy to use. When installed as part
of a HART communicating system, the DVC6200 delivers
prompt notification of current or potential equipment
issues.
n Incorrect regulator setting
n Low air supply or pressure droop
n Dirty air supply
n External air leak (actuator diaphragm or tubing)
n Calibration shift
n Valve stuck
n Piston actuator O‐ring failure
n Excessive valve assembly friction
n Excessive valve assembly deadband
Performance Diagnostics enable condition and
performance monitoring of the entire valve assembly
(not just the digital valve controller) while the valve is
actively controlling the process. When conducting
Performance Diagnostics tests, the valve does NOT move
beyond the normal setpoint changes driven by the
process controller. The DVC6200 uses statistical
algorithms to determine condition and performance
related issues based on live readings from the many
on‐board sensors. Results are then displayed graphically,
with severity indicated by a red/yellow/green indicator
(figure 1). A detailed description of the identified issue as
well as suggestions for recommended actions are
provided.

n Elastomer failure in the DVC6200
n Broken actuator spring
Performance Diagnostics also provide access to
full‐stroke dynamic testing of the valve assembly
including; valve signature, dynamic error band, step
response, and stroke check. These tests change the
instrument setpoint at a controlled rate and are
performed while the valve assembly is isolated from the
process.
