Fisher 67CFR and 67DFR Pressure Regulator DVC2000 Series Digital Smart Valve Controller Positioners

Fisher's FIELDVUE DVC2000 is a microprocessor-based digital valve controller that processes 4-20 mA DC inputs to generate pneumatic outputs for actuator control. Its compact design (low-profile) facilitates easy mounting on various actuators, with a two-stage positioner architecture providing high static gain (pre-amplifier) and dynamic air delivery (power amplifier). The non-contact feedback eliminates linkages, reducing parts count and maintenance. Supporting HART 5 protocol, it enables advanced diagnostics and multi-language LCD interface. Certified for intrinsically safe operations, it ensures compliance in hazardous areas while minimizing air consumption for energy efficiency.

• Positioner Design: Two-stage with high gain for precise small-signal control and low steady-state consumption (0.08 scfm at 20 psig).
• Feedback System: Linkage-less, non-contact for zero wear and simplified retrofit; supports linear/rotary motions.
• Diagnostics: Auto diagnostic, valve signature, partial stroke testing; alerts for travel deviation, air supply, and friction via HART.
• Communication: HART 5 for remote setup, monitoring, and integration with AMS/ValveLink; burst mode for continuous updates.
• Safety Approvals: ATEX IS (II 1 G Ex ia IIC T4/T5/T6), CSA/FM IS/Non-incendive, IECEx.
• User Interface: Local LCD with push buttons for setup, calibration, and multi-language support; auto-tune for optimization.
• Environmental Protection: IP66-rated aluminum housing; -40 to 85°C operating range; vibration tolerance 5 g (10-1000 Hz).

Engineered for demanding control loops in petrochemical, refining, and pharmaceutical sectors. Supports throttling on globe, rotary, and V-ball valves with single/double-acting actuators. Suitable for intrinsically safe installations in Class I Div 1/Zone 0 environments, enabling remote diagnostics to minimize field visits.

• What is the two-stage positioner benefit? Pre-amplifier ensures sensitivity to small inputs; power stage optimizes air flow for efficiency.
• How to access HART diagnostics? Use 475 Communicator or ValveLink software for valve signatures and alerts.
• Compatible with double-acting actuators? Yes, with appropriate pneumatic connections.
• What if air consumption is high? Check for leaks or recalibrate; steady-state is minimal at 0.08 scfm.
• Firmware upgradable? Yes, via HART for enhanced features.
