Fisher DVC6200 FIELDVUE Digital Valve Controller – Advanced Valve Diagnostics & Precise Positioning | FIELDVUE DVC6200 Platform
Engineering Background
The Fisher DVC6200 is part of Emerson’s industry-leading FIELDVUE series of digital valve controllers, engineered to deliver precise pneumatic positioning for control valves in demanding process environments. Designed for both HART® and Foundation Fieldbus™ communication protocols, the DVC6200 integrates seamlessly into modern DCS and safety instrumented systems, providing real-time valve diagnostics and predictive maintenance data that reduce unplanned downtime.
Product Positioning
Targeted at procurement engineers and instrumentation specialists in oil & gas, chemical processing, power generation, and pulp & paper industries, the DVC6200 replaces legacy pneumatic positioners with a smart, communicating device that supports AMS Device Manager, ValveLink software, and HART-enabled field communicators. It is the preferred choice for SIL 2 partial stroke testing (PST) applications and critical control loops requiring IEC 61508-compliant safety validation.

Proven Application Environments
- Oil & Gas: Wellhead control, separator pressure regulation, pipeline flow control
- Chemical & Petrochemical: Reactor feed control, distillation column pressure, heat exchanger bypass
- Power Generation: Turbine bypass, boiler feedwater, steam conditioning valves
- Pulp & Paper: Digester pressure, bleach plant flow, recovery boiler control
- Water & Wastewater: Pump discharge, filter backwash, dosing control
- Pharmaceutical: CIP/SIP steam control, clean-room HVAC, bioreactor pressure
Engineering Advantages
- Advanced Valve Diagnostics (AVD): Continuous monitoring of valve signature, friction, dead band, and supply pressure – enabling predictive maintenance without process interruption.
- Non-Contacting Position Sensor: Eliminates mechanical wear on the feedback linkage, extending MTBF in high-cycle applications.
- Dual-Protocol Flexibility: Single hardware platform supports both HART and Foundation Fieldbus variants, simplifying spare parts inventory.
- Partial Stroke Testing (PST): SIL 2-rated PST capability for on-demand proof testing of safety shutdown valves without full closure.
- Integral LCD Display (optional): Local indication of valve position, set point, and diagnostic alerts without a field communicator.
- Low Power Consumption: Operates from loop current as low as 4 mA; no external power required for HART variant.
System Architecture & Signal Flow
The DVC6200 receives a 4–20 mA set-point signal (HART) or digital set-point via Fieldbus segment. The internal microprocessor compares the set-point to the non-contacting magnetic position feedback and drives the I/P converter and pneumatic relay to modulate output pressure to the actuator. Diagnostic data is transmitted upstream via HART multivariable or Fieldbus function blocks to AMS Device Manager or any HART-capable DCS. The integrated travel accumulator and cycle counter log valve usage for maintenance scheduling.
Sourcing & Quality Verification
- All Fisher DVC6200 units supplied by Konmask.com are sourced from authorized Emerson distributors or verified surplus channels with full traceability documentation.

Technical FAQ
- Q: What is the difference between DVC6200 and DVC6200 SIS?
- The DVC6200 SIS is specifically certified for Safety Instrumented Systems (SIS) per IEC 61508 SIL 2/3, with dedicated PST function blocks and a separate safety manual. The standard DVC6200 supports PST but is not independently SIL-certified for SIS applications.
- Q: Can the DVC6200 be mounted on non-Fisher actuators?
- Yes. Using the appropriate remote mount bracket kit, the DVC6200 can be installed on most rotary and linear actuators from other manufacturers. A feedback arm and linkage kit is required.
- Q: What software is required for configuration and diagnostics?
- Fisher ValveLink™ software (SNAP-ON for AMS Device Manager) or any HART 5/6/7-compatible field communicator (e.g., Emerson 475/375). Foundation Fieldbus variants are configured via standard FF configuration tools.
- Q: Is the DVC6200 compatible with Emerson DeltaV DCS?
- Yes. The Foundation Fieldbus variant integrates natively with DeltaV via H1 Fieldbus cards. The HART variant is supported via HART I/O cards or wireless HART adapters (Emerson WirelessHART).
- Q: What is the typical lead time for DVC6200?
- Ex-stock units ship within 3–5 business days. For specific variants (stainless housing, high-temperature trim, SIS-certified), lead time is 2–4 weeks. Contact us for current availability.
