Packing selection used to be relatively simple, but more stringent environmental regulations have made it much more challenging. Low-emissions packing solutions provide compliance, along with other benefits, as shown in my article in the June issue of Hydrocarbon Processing, titled Added Benefits of Control-Valve Environmental Packing.
Control valves in liquified natural gas applications must operate reliably under high pressure and cryogenic temperatures to achieve gas separation and liquification. This is especially true for the main cryogenic heat exchanger (MCHE), where the closely-coupled Joule-Thomson (J-T) control valves feeding the MCHE help optimize operation of the most critical area in the entire process.
In the world of laser cutting, where precision is paramount, engineers rely on direct acting proportional regulators to achieve rapid system changes and maintain the quality of cuts. One area where proportional control is crucial is the gas assist system.
Control Valves would control ideally the process without any interface to the outside. Although, that’s not practical with today’s technology. Control valves are by design an interface between the process and the outside. This interface can cause some level of...
I received a question from an earlier post, End of Life Expectancy for Final Control Elements in Safety and Control Systems, by Emerson’s Riyaz Ali. The instrument & control engineer who came upon the blog post wrote…
En este episodio el experto José Everardo Molina profundiza sobre la tecnología TopWorx de monitoreo y detección de posición de válvulas de proceso en aplicaciones industriales que permite una mayor rentabilidad y reducir los tiempos de inactividad de las aplicaciones...
When is it possible to use control valves like final elements for SIS [safety instrumented system] application? I am looking for other useful documents and technical requirements when it is possible to use only control valves as the final element instead of on/off valves and not in combination with it in the SIF [safety instrumented function] application.
Three new short, YouTube videos are part of the Control Valves Basics playlist which also has quite a number of other videos to quickly ramp you up the learning curve on basic knowledge of control valves.
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.
¡Las válvulas de aislamiento juegan un papel crítico en aplicaciones de seguridad en las industrias!. Conozcamos con nuestros especialistas, Ricardo Jarero y Luis Miguel de la Cruz, la tecnología detrás de este tipo de válvulas y sus principios operativos. ¿Te...
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 Emerson Exchange Americas virtual series, Emerson’s Reid Youngdahl, Trevor Stoakes and Michael Wyatt show ways to visualize control valve noise and ways to reduce it.
