In the early seventies, the future of FC Barcelona was looking particularly bleak. It was 1973 and it had been 13 years since Barcelona had won the national title. The new season had just begun.The team was at the bottom of the league.

3D printing has its advantages when printing polymers for critical applications. PEEK (Polyetheretherketone) for valve seats is a such a critical material-application combination. Italian company Roboze claims it has developed a 3D-printer and extruder that enable the production of such materials.

Water is an indispensable natural resource as it is directly linked to the preservation of life, the generation of energy, and economic development. With the expansion of the world’s population and the increase of droughts or flooding in certain regions, the need for clean water will continue to escalate. This development will not only impact the water production industry, but will also have a major impact on the wastewater treatment infrastructure.

As regular readers of valve World Magazine may recall, Dr. Baumann’s article in the May 2018 issue of Valve World gave an easy-to-use graphical method of estimating hydro-noise from control valves in liquid applications. This second article presents an equally versatile method for estimating aerodynamic noise caused by gases.

The optimization of plant layout is important in any project needing to utilize the available space in a compact manner and also to achieve better maintainability and operability. The degree of optimization becomes even more important in the case of modular projects, to maximize the extent of modularization. This paper discusses the module design philosophy and various plant and piping layout considerations for vessels, pumps, compressors, heat exchangers and air coolers during modularization.

Interview with Bengt Westman, Managing Director at the AFAB refuelling depot at Stockholm’s Arlanda International Airport. Before your next flight, take a moment to consider how your plane has been refuelled – and the steps taken to ensure that fuel is 100% free from any contaminants.

“The future of anti-surge control valves (ASCV) lies in electric actuation, like the servomechanism that Shell developed with Festo. It is less complex than pneumatic actuation and so requires less maintenance and less expertise to set up.”

Held from 27 to 29 November In Düsseldorf, Germany, the Valve World Conference and Expo again scored highly amongst presenters, delegates, exhibitors and visitors alike, thanks to the unique concentration of flow control expertise, engineering and passion in a single location.

The variety in modular double block and bleed (MDBB) valves is staggering – the millions of possible combinations drives up cost for end users. By implementing delayed customisation, suppliers can reduce supply chain complexities.

It is with great sadness that we report of the death of our colleague, boss, friend, mentor and – above all - inspirator, Donald Wiedemeyer, at the age of 58.
