Energy

High pressures, cavitation and abrasion put high wear on control and shut-off valves in the power/energy industry where long service lifes and and precise control are required at the same time. The unique valve designs from Schubert & Salzer prove themselves every day in numerous applications in large coal or nuclear power plants, biomass or waste incineration plants, on steam boilers large diesel engines and emergency generators. Fluids are feed water, cooling water, steam, exhaust gas but also media for treatment of exhaust gases like ammonia or lime stone.

Sliding gate and segmented disc valves are used especially in steam and feed water and condensate applications. The large rangeability and high flow capacities of ball sector valves make them an attractive solution in district heating applications. Our robust pinch valves again are being use in desulfurisation systems, whilst sliding gate valves with their high precision with small Kvs values are a common solution in SCR and SNCR De-Nox applications. Those are just a few application examples – we will have a solution also for your application.

valve, eval europe, kuraray

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.

valve, dow, Power plant

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.

valve, elsta, heating power plant

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.

valve, airport

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.
