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 TM 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 it provides the information required to create streamlined work processes .
Controllers for control and on-off valves
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 Fisher™ FIELDVUE™ DVC7K
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 . If analysis reveals a problem , an alert is created , which can be viewed locally or remotely , providing the information required to create streamlined work processes that save time and money . All alerts

include recommended actions to fix the problem , a new feature for digital valve controllers , and unique to the industry . Previously , digital valve controller data had to go to a host system to be processed and prepared for viewing , however , with the intelligence of this system , data is now accessible without requiring access to the host software . All information can be viewed at the DVC7K ’ s local user interface , nearby via Emerson Secure Bluetooth ® wireless technology , or remotely after it is transmitted via a wired digital network to a host , such as a distributed control or asset management system . The local user interface provides indication of valve health at a glance via LEDs , and users can drill down from the interface home screen to find more information . Emerson Secure Bluetooth enables access to one or more digital valve controllers at distances up to 30 feet from any device capable of supporting Bluetooth , such as a smartphone or tablet . Whether the information is viewed locally , nearby , or remotely , plant personnel can use it to drive awareness of valve health . With increased remote connectivity and Advice at the Device local diagnostics , flexibility increases , providing the information needed for fast decisions and quick action to address arising issues . The DVC7K can be specified for all new valve purchases , and it can be retrofitted to most existing valve installations , in either case quickly and easily commissioned via the local user interface . With over three million FIELDVUE units sold and ten billion hours plus of field operation , long-term reliability and performance is proven in use , a key requirement as Fisher and other Emerson valves are often used in critical process industry applications .
