ASCO Solenoid Spool Valves Fisher FIELDVUE DVC2000 Smart Digital Valve Controller Valve Positioners

The Fisher FIELDVUE DVC2000 is a compact, HART-communicating digital valve controller designed for precise pneumatic valve actuation in industrial processes. It converts a 4-20 mA input signal into a pneumatic output to drive control valve actuators, offering easy mounting and retrofit compatibility with most Fisher and non-Fisher valves. Featuring a two-stage positioner design, it ensures high static gain for responsive control and minimal steady-state air consumption. The linkage-less feedback system eliminates physical contact between the valve stem and positioner, reducing wear and simplifying maintenance. With an intuitive LCD interface supporting multiple languages, it meets intrinsically safe and non-incendive standards, making it suitable for hazardous environments. This controller enhances operational efficiency through auto-calibration, diagnostics, and scalable functionality.

• Linkage-Less Feedback: Non-contact system maximizes cycle life by eliminating wear parts and physical linkages, reducing mounting complexity.
• Two-Stage Positioner: High gain pre-amplifier for small signal responsiveness; power amplifier for optimal air volume delivery with low consumption.
• User Interface: Enclosed push-button LCD with multiple language options (English, German, French, Italian, Spanish, Chinese, Japanese, Czech, Portuguese in two packs) for easy setup and operation.
• Auto-Tuning and Diagnostics: Automatic tuning for performance optimization; built-in diagnostics for alerts on issues like low air supply or high friction.
• HART Communication: Enables remote configuration, monitoring, and diagnostics via HART protocol, supporting integration with asset management systems.
• Safety Compliance: Intrinsically safe (IS) and non-incendive approvals (ATEX, CSA, FM, IECEx) for hazardous areas; IP66 enclosure for environmental protection.
• Mounting Flexibility: Integral mounting on Fisher GX, 657/667 actuators; options for sliding-stem linear and quarter-turn rotary valves.

The DVC2000 excels in process industries such as oil & gas, chemical processing, and power generation, where precise valve control is essential. It is used for throttling applications on sliding-stem linear and quarter-turn rotary valves, supporting both single and double-acting actuators. Ideal for hazardous locations requiring IS approvals, it integrates with control systems for remote monitoring and diagnostics, reducing downtime in critical loops.

• How do I perform auto-tuning? Use the LCD push buttons to initiate auto-tune, which optimizes performance based on actuator response.
• What if the positioner detects high friction? Diagnostics alert via HART; check for valve issues or recalibrate.
• Can it be retrofitted to non-Fisher valves? Yes, with appropriate mounting kits for compatibility.
• What languages are supported? Two packs: Pack 1 (English, German, French, Italian, Spanish, Chinese, Japanese); Pack 2 (English, German, French, Italian, Spanish, Czech, Portuguese).
• How to handle low air supply? Built-in alert notifies via HART; ensure supply pressure meets min requirements.
