The Fisher DVC6205/DVC6215, a remote-mounted split-type intelligent valve positioner from Emerson, is designed for extreme industrial environments, including nuclear power, pulp and paper, and chemical industries. Its core advantages include:
No-Linkage Non-Contact Technology
Equipped with the patented FIELDVUE™ linkage-free feedback system, it detects valve position via magnetic induction and Hall-effect sensors, eliminating wear, corrosion, and vibration issues caused by traditional mechanical linkages. This design ensures reliability in extreme temperatures (-52°C to +120°C) and high-vibration environments.
Remote Split Installation
The feedback unit and control module are separated, allowing the control unit to be installed up to 300 feet (91 meters) away from the valve. This is ideal for confined spaces or hazardous areas (e.g., nuclear reactor zones), with pneumatic tubing limited to 15 meters to ensure signal stability.
Multi-Certification & Robust Protection
Certified by CSA, IECEx, ATEX, FM, and others, it achieves IP66 protection for hazardous zones (e.g., flammable gas environments). Lloyd’s Register certification further validates its suitability for marine and offshore platforms.
Smart Diagnostics & Compatibility
Supports HART communication and integrates ValveLink™ software for remote diagnostics, enabling real-time monitoring of valve friction, pneumatic errors, and predictive maintenance. Compatible with linear, rotary, and GX/657/667 actuators, it offers single/double-acting configurations and 4-20mA feedback options.
Applications:
Nuclear plant cooling systems, high-temperature steam control in paper mills
High-pressure differential regulation in petrochemical processes, corrosive offshore platforms
Continuous process industries requiring long-term stability
