Oil and Gas Industry Pneumatic Valve Positioner Fisher DVC2000 DVC6200 3661 and Spirax Sarco Control KE73 and Valve Positioner

The Fisher FIELDVUE DVC6200 is a high-performance digital valve controller that converts a 4-20 mA control signal into pneumatic output for accurate valve positioning. It supports HART communication for setup, monitoring, and diagnostics, helping operations stay closer to setpoint for better process control and product quality. Available in aluminum or stainless steel, it works with single- or double-acting actuators in linear or rotary applications.

• Linkageless feedback using contactless Hall-Effect technology with stem/shaft-mounted magnet array for reliable, low-maintenance positioning.
• Advanced diagnostics via ValveLink software or AMS, including travel history, pressure readings, and valve performance insights.
• One-button setup and calibration for quick commissioning.
• Low air consumption with optional low-bleed relay to reduce operating costs.
• Integral pressure sensors for real-time monitoring of supply, output, and actuator pressures.
• SIL 3 capable (HART version when input is 0 mA/0 VDC) for safety-critical uses.
• Modular design with options for hazardous area certifications.

Widely used for control valve positioning in oil & gas, refining, chemical processing, power generation, and pulp & paper industries—especially where diagnostics help reduce unplanned downtime and improve loop performance.

Q: How does it handle diagnostics?

A: It uses built-in pressure sensors and travel data for predictive insights via ValveLink or AMS software.

Q: Is linkage required?

A: No—linkageless design uses magnetic feedback for most setups.

Q: What about air usage?

A: Standard relay is low consumption; low-bleed option further reduces it for efficiency.

Q: Can it be used in hazardous areas?

A: Yes, with approvals for explosion-proof, intrinsically safe, and other classifications.

Q: What's the temperature range?

A: -40 to +85 °C standard; down to -52 °C with extreme temperature elastomers.
