Safety valves for hydrogen applications
More than 600 billion cubic meters of hydrogen are produced each year world-wide for the process industry. The technology for using hydrogen as an energy source in combustion engines or via fuel cells is now ready to replace petroleum products in the future. The advantages of hydrogen as an energy carrier are: • Neutral CO2-footprint • Flexible energy storage: in liquid or gaseous form • Power to X: flexible us as an energy supplier in fuel cells, fuel in combustion engines and as a coke substitute in steel production. With the addition of CO2, it can also be used as a fuel and combustible. Technical challenge for safety valves in hydrogen applications: • Storage and transport of hydrogen cryogenic (up to -253 °C) • in refuelling systems pressures of up to 900 bar for cold liquefied hydrogen, in future up to 900 bar • Use of materials being insensitive to hydrogen embrittlement Recommendation: • Austenitic steels (1.4404, 1.4408) for wetted parts • stellited discs and nozzles for cryogenic temperatures (from 150°C to absolute zero) for best sealing results
SISTO Diaphragm Valves
We have recently established ourselves as Sisto's new partner in Switzerland and will now be selling their high-quality diaphragm valves as well as industrial and aseptic valves. Sisto Armaturen SA, with around 200 employees, develops and produces diaphragm valves at its location in Echternach, Luxembourg, which are used in various areas of application. We attach great importance to the quality and rapid availability of the products and are proud to now be able to offer these high-quality valves in Switzerland.
