The Neles™ NDX 2.0 delivers on sustainability

Many have asked what’s so different about the new Neles NDX 2.0 valve controller. While there are several technical developments worth discussing, we’ll start by looking at the considerable increase in the potential to improve the sustainability of valve assemblies and the processes they are a part of. The new Neles NDX has a far greater versatility for different actuator types and sizes. The 2.0 is pretty much a universal, one for all solution that serves equally well ...

The Optimal Valve for Tank Protection

Worldwide, the storage of crude oil, petrol and other refinery products in stationary tank farms is getting more and more important. Investments in storage tanks are increasing for several years. The biggest trend today is the increasing of storage volumes. Based on the hazard potential to people and inventory, as well as fatal accidents in the past (like the fire in the Bruncefield tank farm in 2005. It started with a 40-minute uncontrolled overfilling and an explosion. The ...

Top of Side Entry? Your Choice

The capacity of LNG plants has significantly increased over the years and geopolitical conflicts will likely push the market to new Liquefaction facilities, carriers, LNG terminals and regasification units. Valves are a critical component at each stage. Valve performance and reliability are vital to the whole process. The unique design, high quality manufacturing and material selection of Zwick Armaturen makes them ideal for LNG installations and other Cryogenic applications.

TRI-BLOCK Double Block & Bleed (SIL3)

The Double Block and Bleed design features every technical advantage which the series TRI-CON has plus there is a true double block and bleed feature which delivers zero leakage. By using this design, the former two valve system with a spool piece becomes obsolete. This fact is not only important for in­stallation since you have to install only one valve body in the pipeline, but also only one actuator or gearbox is required. With ZWICK’s unique design of the linkage between ...
