Application Report thyssenkrupp AT.PRO tec
Revolutionary oxygen impulse technology for steel production
thyssenkrupp AT.PRO tec GmbH is well known for the development of the sequence impulse process. When used on cupola furnaces, it considerably increased their cost-effectiveness in the past. In over 10 years of development work with Schubert & Salzer as their partner, Dr Rainer Klock and the team at AT.PRO tec succeeded in getting the SIP technology to work on blast furnaces, too, with the help of sliding gate valves. The story of a researcher on the way to becoming a plant manufacturer.
Application Report Veolia Water Technologies
Sliding gate valves are optimising Belgium’s largest facility for RO water purification
Veolia Water Technologies has built an ultra-modern plant to produce drinking water in Ostend, Belgium. In a multistage filtration process, the local water supplier is now producing drinking water of excellent quality – far above the statutory requirements. At critical points of the process – during reverse osmosis, filtration with activated carbon and remineralisation of the water – sliding gate valves made by Schubert & Salzer Control Systems are responsible for regulating pressure and flow rate.
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 Van Drunen Farms
Valve Replacement Optimises Freeze-Drying Productivity
Simpler and faster commissioning, approx. 15% reduction of the cycle time, considerable productivity increase as a result and substantially less downtime – these were the results gained by one of the world’s largest supplier of freeze-dried products, Van Drunen Farms (USA), by simply switching from ball valves to the 7010 angle-seat on-off and 7020 control valves from Schubert & Salzer.
Application Report Avery Dennison
In Touch with Adhesion
In the polymerization of adhesives, the level of precision of the valve technology plays a key role. For this reason, the new Avery Dennison reactor uses the ATEX-certified ball sector and sliding gate valves from Schubert & Salzer.
Application Report Stadtwerke Bielefeld
Efficient control of thermal capacity using ball sector valves in the district heating system of Stadtwerke Bielefeld
In 2011, the plans of the Stadtwerke Bielefeld to carry out major work on the district heating system and replace diverse control valves in the following year took on a concrete form.
Application Report Dow Chemical
Robust segment disc valves also contribute significantly to availability of industrial power plants
At its production site in Stade, the US-American company Dow Chemical Company (“Dow”) operates a state-of-the-art gas and steam turbine power plant which produces not only power but also thermal energy which is necessary for operating the chemical plants. Due to power/heatcogeneration, efficiency rates of more than 80% can be reached.
Application Report Elsta
Dutch thermal power station reduces cavitation damage via the utilisation of Schubert & Salzer sliding gate valves
ELSTA, a joint venture between Delta, Essent and the American company, AES, is one of the most environmentally-friendly thermal power stations on Earth. Compared to older power stations of the same design, ELSTA has a very impressive 75 % efficiency and consequently, makes a significant contribution to reducing CO2.
Application Report Braas
Construction materials industry uses robust control valve in order minimise operating costs
For three years, a ball sector valve has been used beneath the mixer cone at the Braas production facility in Mainburg. Initially, the rapid delivery times and low investment costs were crucial factors in terms of the conversion.
Application Report Naturenergie Cham GmbH
Sliding gate valves open up enhanced flexibility for power plant planners and operators
The biomass combined heat and power plant (BMCHPP) by Naturenergie Cham GmbH generates 2.8 MWh of power from woodchips. The remaining medium steam pressure of 9 bar is supplied to different energy consumers with different requirements.
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.
Application Report Paulaner
Maintaining a constant flow of beer
Since 2010, leading festival tent operators have converted to central beer supply systems at the Munich Oktoberfest.
Application Report Apollo Tyres
Precise steam pressure control at Apollo Tyres
Apollo Tyres South Africa’s Durban plant had been experiencing steam flow control issues on the steam feed into the bladders on their truck tyre presses during the shaping sequence of the tyre curing process.
Application Report Munich Airport
Sliding gate valves optimise airport’s power plant
Sliding gate valves have excellent control characteristics. Munich Airport’s power plant now also benefits from these inherent advantages, as the existing gas flow butterfly valves of two diesel gas pilot ignition (duel fuel) engines were replaced by sliding gate valves.
Application Report Hongta Tobacco & Palmaju Edible Oil
The sliding gate valve reins in costs for steam systems
