3 steps to ensure ESD valve reliability beyond certification

Final elements, such as ESD valves, are a critical part in the safety lifecycle. When they are not working properly, the safety of the entire plant is in jeopardy. To ensure overall plant safety, correct ESD valve selection plays a vital role. A lot of uncertainty prevails around the relatively new standards IEC 61508 and IEC 61511 and how they should be interpreted for safety valves. This blog post looks closer at this issue and sheds some light on what is an essential but confusing subject.

Gaining deeper insight to solve valve cavitation

Since cavitation is one of the most significant causes of wear, it is important to control the impact of the fluid flow. Using advanced computational fluid dynamics (CFD) to model cavitation helps you reach quicker, more efficient results and deeper insight for your designs, avoiding any premature failure of your control valves.

How to choose control valves?

Control valve requirements often differ depending on the process area, application and end user specifications. Process conditions and the range of parameters also vary widely, including pressure, temperature, controllability, cavitation risk, environmental impact, noise and more. Plus, priorities may differ. An end user may want to know more about a valve’s performance, controllability and total life-cycle cost, whereas an EPC contractor may be more concerned about the CAPEX-related costs and delivery times. How do you know where to start – and where to turn for help with quality information you can rely on?

Valves in delayed coking units – why they matter

Refineries need to improve profitability to stay competitive in today’s market. Delayed coking for heavy and sour oil refineries is potentially one of the most profitable operations available to refiners. Since 1994, almost all residue upgrading in the US has been done with delayed coking. And although coking technology may seem mature, innovations continue to bring improvements.

Are you in control of your polymer production?

For efficient and safe plastics production, a polymerization unit relies on numerous control and on-off valves. It’s vital to know you can count on those valves to do their job at all times. The selection of the right valve for each step requires careful consideration. And every detail matters when it comes to running a reliable, profitable plant.

We make customer service up close and personal

Reliability is a core element of what we as a valves partner want to provide. Being close to our pulp and paper customers and having an in-depth understanding of their production processes is a prerequisite for good service. As a Resident engineer at a customer mill, I have a unique point of view in terms of customer proximity and understanding.

Identifying where process efficiency is created

Each and every pulp, paper and bioindustry customer is ultimately looking for the same thing; The ability to make more with less. Increasing the degree of automation and digitalization related to your process valves is a sure way to improve your mills efficiency and reliability.

Moving toward the future with sustainable biofuels

The word “biofuel” has been a known term for many years now. However, we have transitioned into a new period of time when biofuel has become significantly more important globally. But do you know that not all biofuels are actually sustainable? And what makes a biorefinery really efficient? Let’s take a closer look.

We share the same passion of ensuring customer success

“Never give up. Don’t be afraid of making a mistake. Trust is built among us.” We interviewed Glow Yang, Director of Channel Development and Sales, about her inspiring career path and the open culture that Neles has.
