Fisher DVC6200/DVC6200HC Double And Single Action Valve Feedback Positioner
Products Description
The DVC6200 is a HART digital valve controller. It converts a 4-20mA signal to pneumatic output for valve positioning. No mechanical linkage means less wear.Three main jobs: valve positioning, auto-calibration, and HART diagnostics.Works with any pneumatic actuator-sliding-stem, rotary, single or double-acting. One unit does it all.

Fisher DVC6200 HC Applications
1.Oil & Gas Extraction and Harsh Conditions
Designed for throttle valves, separators, gas handling units, and large actuators requiring powerful pneumatic output.
2.Refineries & Petrochemical Plants
Ideal for heavy-duty process units such as hydrotreatment units, reforming units, FCC (fluidized catalytic cracking) valves, and steam/combustion control systems, where fast and stable valve response is critical.
3.Power Generation & High-Energy Steam Systems
Supports large control valves in boilers, turbine auxiliary equipment, and high-pressure steam conditioning loops, meeting the stringent requirements for precise positioning under varying load conditions.
4.Chemical & Industrial Process Control
Suitable for oversized or high-thrust actuators in reactors, cooling/utility networks, and process gas conditioning applications where robust diagnostic capabilities and gas delivery capacity are critical.

FAQ
Q: 1.What are the main features of the Fisher DVC6200HC?
A: It features automatic self-calibration, linkage-free non-contact feedback (if configured), and HART communication for remote diagnostics; if the position feedback signal is lost, the pressure backflow function ensures continuous valve operation; and it integrates easily with ValveLink and plant asset management tools. The DVC6200HC positioner is particularly suitable for general-purpose control valves in refining, chemical, and utilities industries, providing modern diagnostic capabilities while avoiding unnecessary complexity.
Q: 2.How to choose the right Fisher DVC6200 positioner?
A: Choosing a positioner for a high-frequency circulating valve? If your application operates at a cycle frequency exceeding 5 times per minute-such as compressor anti-surge systems, pipeline pig launchers, or intermittent reactors-standard positioners often fail prematurely due to wear. The Fisher DVC6200 HC is designed to handle continuous high-frequency motion. Its internal components are reinforced, and it incorporates adaptive algorithms to effectively eliminate "static friction sticking."
