Aurélien Tissot joins podcast host Jim Cahill in this Emerson Automation Experts podcast to discuss the topic of emissions and the technology opportunities for manufacturers and producers.
Valves, Actuators & Regulators
Amit Patel and Jason Maderic discuss how the TopWorx predictive valve maintenance solutions help customers navigate the world of Digital Transformation to improve areas around production, energy, emissions, reliability, and safety.
In a Control Engineering magazine article, New hydraulic actuator designs offer zero emission options, Emerson’s John Carroll highlights new actuator designs that eliminate these emissions.
David Leavitt joins podcast host Jim Cahill to discuss how triple-offset isolation valves improve storage terminal reliability while reducing overall lifecycle costs compared with other isolation valve technologies.
How to Select Valves for Molecular Sieve Switching Applications article in Plant Services describes the unique and difficult challenges associated with molecular sieve switching valves and the new valve options available to address these issues.
The DVC6200 HW2 digital valve controller provides a unique feature to detect position feedback issues and automatically revert from travel control to pressure control (I/P transducer mode) to keep the valve operational. This can help avoid costly unplanned spurious trips that can affect plant operation.
Riyaz Ali provides clarity on when to assign the SIL suitability for valves used in different scenarios (process control vs. safety shutdown) and establish criteria to assign SIL applicability for the “Final Element”.
Valve sizing and selection has the same opportunity. At Emerson, our Final Control portfolio is unmatched in brand, breadth (wide and deep), and local subject matter expertise.
Emerson’s Katherine Bartels and Adam Harmon address the subject of control valve choked flow in liquid and gas applications in an International Society of Automation Intech article, Choked Flow in Control Valves.
At the 4C Health, Safety & Environmental conference, Emerson’s Derek Kelly highlighted ways to reduce fugitive emissions from tank venting equipment.
In a post, Valve Travel Control-Pressure Fallback, Emerson’s Riyaz Ali shared the process of how a control valve with a digital valve controller could fall back to standard pressure control upon an issue with the travel sensing mechanism.
A Digital Valve Controller, the DVC6200 (HART or Foundation Fieldbus) can detect position feedback problems and automatically revert to I/P [current to pressure] transducer mode to keep the valve operational. This avoids costly unplanned spurious trips, which are critical for plant operational performance.
