Emerson’s new digital valve controller

Emerson has announced the Fisher™ FIELDVUE™ DVC7K Digital Valve Controller, a new design improving upon 30 years of field-proven innovation. The DVC7K features Advice at the Device™ technology with embedded computing and analytics that convert raw data into actionable information locally with Bluetooth® capability, within the device. This means maintenance personnel can receive the data via their phone, tablet, or computer wirelessly without having to be in a control room at the plant location. The new valve controller technology improves the performance, reliability, and uptime of both on-off and control valves—and by extension, an entire process plant or facility—in a wide variety of process industry applications, and provides the information required to create streamlined work processes.

Digital valve controllers are available as accessories for control and on-off valves to provide local analysis of valve data, digital communications with host systems, and other features. These features improve uptime by alerting personnel to developing problems, reduce maintenance costs by providing the actionable information required for proactive rather than reactive maintenance, and cut troubleshooting time in the event of an issue by providing recommended corrective actions. For example, a control valve may be reacting slowly to commands requiring it to move, which is often an early sign of impending issues. The DVC7K will recognize this type of condition, alert personnel, and provide recommendations for fixing the problem.

The DVC7K interprets data to create an optimized path to action by combining patented technology, experience-based algorithms, and continuous real-time analytics with flexible connectivity and easy integration. It uses powerful, real-time, and onboard edge computing to analyze issues and create actionable information, providing real-time awareness of valve health by analyzing data locally via its on-board diagnostics.
