Application Report Eval Europe NV

Sliding Gate Valves improve Chemistry Park Steam Filter Station

Kuraray is one of the world's leading suppliers of ethylene vinyl alcohol copolymers (EVOH), which, for example, provide multi-layer food packaging with a better barrier layer. The steam required for the manufacture of EVOH in the Antwerp Chemicals Park, the location of the Kuraray subsidiary Eval Europe, is provided by a central energy plant. Kurt Hellemans, Senior E&I engineer at Eval Europe, installed the first DN250 sliding gate valves in the steam filter station. After years of experience with the sliding gate valves, he now draws a balance.

Application Report DEVEX Verfahrenstechnik

Cannabis Extraction is based on a Precise Controlling of Cryogenic Temperature Hygiene Processes

The company DEVEX Verfahrenstechnik in Warendorf has taken a decisive step in the direction of extracting cannabis oil with the development of the CryoEXS plant. This makes it possible to extract cannabis oil from hemp and then filter it, connect an ethanol retrieval system, and then refine it in a final step by deploying decarboxylation. Sliding gate valves and aseptic seat valves from Schubert & Salzer provide the highest degree of control precision – even within the sensitive cryogenic temperature range.

Application Report Brüder Unterweger GmbH

Production in traditional natural oil distillation increased more than ten-fold

The traditional East Tyrolean company Brüder Unterweger GmbH has been distilling essential oils for natural cosmetics for more than one hundred years. The highly complex distillation process had to be drastically expanded and made more efficient so that the increasing demand could be met. The control and shut-off valves from Schubert & Salzer Control Systems had an important role to play.

Application Report BMW

Sliding gate valves optimise the process reliability of light metal die casting

In low pressure die casting, e.g. light metal engine blocks, the casting machines are filled by pressurising the furnaces. This requires highly precise pressure control along defined pressure curves in order to be able to produce a high quality casting and, for example, to prevent the metal pillars from moving around in the mould. In each case, BMW replaced the pressure control previously used for this purpose in its Landshut light metal foundry with a single sliding gate valve from Schubert & Salzer Control Systems.
