Generally, depending upon the design of internal components of smart devices and their response to control change from the controller input signal, pneumatic parts like I/P (current-to-pressure transducer) and pneumatic relays are tailored to optimize control performance.
Digital Valve Controllers for Net-Zero Objectives
Emerson’s Riyaz Ali presented Digital Valve Controller Used with Final Control Elements Inching Towards Net Zero Emission at the 2024 Emerson Exchange conference in Düsseldorf, Germany. Here is his presentation abstract: Energy consumption is a big part of process...
Moving Beyond Pneumatic Standalone Controllers
The article, When Pneumatic Standalone Controllers Age Out, discusses alternative process controller designs that address the issues with pneumatic controllers, while providing a host of additional benefits.
Digital Valve Controller Considerations
Modern digital valve controllers with onboard valve monitoring and diagnostics reduce unplanned outages and increase profitability. End users choosing controllers should carefully evaluate the features offered to take advantage of the significant advancements seen in the last few decades.
Digital Valve Controller Employs Edge Computing
Valve controllers play a vital role in industrial processes, ensuring that control valves are positioned accurately under changing process conditions. Building upon fifty years of valve controller improvements, the new Fisher™ FIELDVUE™ DVC7K digital valve controller...
Gain Asset Health Insights with Emerson’s Digital Valve Controller
Control and on-off valves carry out critical functions in process plants and facilities worldwide, so their performance and condition must be closely monitored. New digital valve controllers provide this functionality, along with other tasks, improving the operation and uptime of these valves. These controllers also enable optimization of maintenance activities by predicting failures well in advance, allowing for proactive instead of reactive actions.
Advice at the Device™ for Your Valves
The Fisher FIELDVUE DVC7K digital valve controller offers Advice at the Device technology with real-time analytics for valve health diagnostics and prescriptive corrective actions. In a ControlGlobal.com article, Advice at the device—and remotely, Emerson’s Tom Brandau is quoted on the history of digital valve controller technology.
Improving Performance with Digital On-Off Valves
I’ve often written about how digital valve controllers improve control valve performance and ongoing maintenance. But how about on-off valves? In this Valve World Americas featured story, How Digitized On-Off Valves Improve Operations, Emerson’s Riyaz Ali explains how...
The Future is Now for Predictive Valve Maintenance
Saurabh Pathak & Naman Tahan share how advances in digital valve controllers, diagnostic software & network communications are enabling significant reductions in maintenance costs & unplanned outages.
Optimizing Valve Compressed Air Consumption
For air-operated control valves, the pneumatic power at a constant supply pressure is proportional to the mass flow rate of instrument air. The pneumatic/eletro-pneumatic/microprocessor-based digital valve controller is used on most control valves operated in closed-loop control, where the input signal is continuously changing.
Valve Reliability in Safety Instrumented Functions
In a Hydrocarbon Engineering article, Improving safety shutdown valve reliability, Emerson’s Stanley Amirthasamy and Lura Parrent share ways to improve the reliability of final elements when they are safety valves. They open noting how safety valves are used to bring a process to a safe state.
