Emerson’s Fisher Instruments has been producing its Wizard pneumatic controllers since the 1940s, refining and revamping them every 20 years or so. Along the way, the company produced its electro-pneumatic controllers, and more recently developed its Fisher™ FIELDVUE™ digital pneumatic controllers (DPC). In all, Emerson estimates there are more than 1 million of its pneumatic controllers presently operating.
Valves, Actuators & Regulators
Modern electric valve actuators offer far more than their simpler predecessors, and as a result they are seeing widespread adoption throughout the process industries. Advanced monitoring software provides early notice of developing problems as well as actionable suggestions, empowering maintenance teams to intervene and prevent production impacts.
The L2t Liquid Level Controller solution is straightforward and inexpensive to install in existing oil separator vessels, and it significantly reduces maintenance and lost production costs, especially compared to level switch solutions. It is also emission free, a significant improvement over systems using natural gas as a motive force.
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.
While high reliability clearly entails high availability, what is less obvious is that reliability also enhances sustainability. In this October 2023 issue of InTech, titled “Executive Corner: Reliability Through the Lens of Sustainability,” explains why.
Digital transformation of field instrumentation can spark one’s imagination with new concepts, including the possibility of data harvesting from automated on-off valves. Automated on-off valves are typically used in a basic process control system (BPCS) or safety instrumented system (SIS). In these and other automation systems, they must function properly to optimize performance, availability, and reliability. The data provided by smart on-off valves can be used to increase uptime, reduce maintenance costs, and improve safety.
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...
In a CHEManager International article, Innovative and Disruptive Automated Valve Package offers Decarbonization Solution, Emerson’s Knut Riegel shares how advancements in valve actuation technology fitted on isolation and shutoff valves have enabled reduced emissions.
Leaders worldwide continue to pursue hydrogen as a dependable energy carrier in the global energy mix. But hydrogen, as a light gas, has challenges in the supply chain from production through ultimate use as an energy carrier. Challenges that Emerson has addressed include hydrogen embrittlement, permeation, and leak detection to make the transportation and consumption of hydrogen blended gases a safe and eco-friendly reality.
In refineries and petrochemical plants, frequent contact with process media can result in premature corrosion of valves and related components. To help prevent this, vendors can provide expert advice and, in some cases, lab testing to verify compatibility between...
Choosing a valve maintenance company that you can trust is difficult. During a shutdown or outage, you want your plant back up and running as quickly and safely as possible, while staying within budget and completing reliable repairs. Here are some tips from an...
With Clarkson KS1 knife gate valves from Emerson, the improvement was dramatic and immediate. After 8 months, the new valves remain in service, never having required a repair or change out. The installed cost of each valve was less than $27,000, so the project paid for itself in just over two weeks, and it has been generating nearly $10,000 per week in savings since.
