Cryogenics with the gases like helium, hydrogen and sometimes also with neon, nitrogen, or air gain today more attraction as enablers for new green technologies in the energy sector as well as further industrial areas as in chemistry, semiconductor, steel and glass production etc.
Cryogenic helium in all stages is used to cool superconducting devices allows efficient high energy research and fusion research. Liquefied hydrogen is a high dense energy vector and could be at the same cooling superconducting cables and power devices. Neon seems a potential candidate to enable highly efficient cryogenic processes. Subcooled liquefied nitrogen is used to cooling high temperature superconductor cables and devices in the power system. The cryogenic process of liquefying and warming up air is used to store fluctuating production renewable power.
Consequently, valve industry face techno-economic complex challenges to answer the demands of this expanding sectors that will play an essential role the upcoming decades.
This paper describes identified techno and economic challenges for a modern cryogenic valve. Focus is on applications in liquified hydrogen but also considerations regarding the special requests for helium are highlighted. Some key design topics are
Thermal efficiency.
Flexibility to absorb thermal contractions in the connection piping.
Interior and exterior tightness
Valve flow capacity.
Precise flow control
Flexible actuating system with low energy consumption
Suitable for industrial serial manufacturing processes
In this paper, AMPO POYAM VALVES will present an innovative solution concept that meets the challenges of the cryogenic service condition over the entire temperature and pressure range and brings a modern valve concept to the market considering up to date manufacturing technologies and thus offers added value to the efficiency of the high-tech cryogenic processes.
