Emerson introduces the Fisher FIELDVUE DVC7K digital valve controller, representing a significant advancement in design built upon three decades of field-proven innovation. This cutting-edge technology incorporates Advice at the Device, embedding computing and analytics to convert raw data into actionable information locally. The DVC7K boasts Bluetooth capability within the device, enabling maintenance personnel to wirelessly receive data on their phones, tablets, or computers without the need for a control room presence at the plant location.
This state-of-the-art valve controller enhances the performance, reliability, and uptime of both on-off and control valves across a broad spectrum of process industry applications. It offers valuable insights to streamline work processes, improving overall efficiency. As digital valve controllers are available as accessories for control and on-off valves, they provide local analysis of valve data, digital communications with host systems, and other features. These features contribute to increased uptime by alerting personnel to potential issues, reducing maintenance costs through proactive maintenance, and minimizing troubleshooting time by offering recommended corrective actions.
The DVC7K interprets data, leveraging patented technology, experience-based algorithms, and continuous real-time analytics with flexible connectivity and easy integration. It utilizes powerful onboard edge computing to analyze issues and create actionable information, offering real-time awareness of valve health through onboard diagnostics. In case of any problems, the system generates alerts that can be viewed locally or remotely, facilitating streamlined work processes with time and cost savings. A notable feature is the inclusion of recommended actions to address identified issues, a novel aspect for digital valve controllers and unique in the industry.
Traditionally, digital valve controller data needed to be sent to a host system for processing and viewing. However, the intelligence of the DVC7K enables direct access to data without requiring host software access. Information can be easily viewed locally at the DVC7K's user interface through Emerson Secure Bluetooth wireless technology or remotely after transmission via a wired digital network to a host system like a distributed control or asset management system.
The local user interface offers a quick indication of valve health through LEDs, allowing users to drill down from the home screen for more detailed information. Emerson Secure Bluetooth ensures access to one or more digital valve controllers within a 10-meter range from any Bluetooth-enabled device, such as a smartphone or tablet. Whether viewed locally, nearby, or remotely, plant personnel can leverage this information to enhance awareness of valve health.
With enhanced remote connectivity and Advice at the Device, the DVC7K provides increased flexibility in local diagnostics, enabling quick decision-making and prompt action to address emerging issues. It can be specified for new valve purchases or retrofitted to existing installations, with easy commissioning via the local user interface. With over three million FIELDVUE units sold and over ten billion hours of field operation, the long-term reliability and performance of this technology are well-established, meeting the critical requirements of various process industry applications where Fisher and other Emerson valves are commonly employed.
