Description

Fisher DVC6200F Digital Valve Positioner

Product Dimensions：

The Fisher FIELDVUE DVC6200F is a premier digital valve controller designed for FOUNDATION Fieldbus networks. It is a link-active scheduler (LAS) device that transforms a standard control valve into a smart, communicating asset.

🛑 Product Overview

The DVC6200F utilizes a linkage-less, non-contact feedback system. By removing physical contact between the valve stem and the controller, it eliminates wear-and-tear issues caused by vibration, making it incredibly durable in harsh industrial environments.

📊 Technical Specifications

✨ Key Advantages

• Reliability (Linkage-less Design): Since there are no levers or linkages to break or wear out, the unit is highly resistant to vibration and mechanical failure.

• Performance Diagnostics: It provides real-time data on valve health. You can perform “Step Response” or “Valve Signature” tests without pulling the valve from the line.

• Interoperability: Being FOUNDATION Fieldbus certified, it integrates seamlessly into existing DCS (Distributed Control Systems) like Emerson DeltaV.

• Modular Maintenance: The electronics are isolated from the pneumatic terminal, allowing for easy field repairs.

• Enhanced Safety: Certified for use in SIL 3 loops, ensuring it meets high-integrity functional safety standards.

⚠️ Important Considerations (Usage Notes)

1. Air Quality: The instrument requires clean, dry, oil-free air (ISA Standard S7.0.01). Contaminated air is the #1 cause of pilot valve failure.

2. Magnetic Interference: Because it uses magnetic feedback, ensure no strong external magnetic fields are placed directly next to the sensor.

3. Firmware Compatibility: Ensure the device’s Device Description (DD) file matches your host system’s version for full functionality.

4. Proper Venting: Ensure the exhaust vent is not obstructed, especially in environments where icing or debris is common.

🏭 Common Applications

• Oil & Gas: Critical control in refineries and offshore platforms where vibration is constant.

• Chemical Processing: Managing corrosive or volatile fluids with high precision.

• Power Generation: Feedwater control and steam turbine applications.

• Pulp & Paper: Handling heavy-duty slurry valves.
