Vavles and Cryogenic Components

Market-leading cryogenic technology

Sealed, even at the edge of possibility.

We have been redefining standards in cryogenics since the 1970s. Our comprehensive portfolio of precision components enables the reliable control of fluids at temperatures close to absolute zero – where conventional technology fails.
Engineers worldwide trust our expertise in demanding applications in the liquefaction and cooling of helium and hydrogen.
Our technological expertise also extends to components for other technical gases such as argon, neon, xenon, nitrogen, and oxygen.
Our innovative strength is particularly evident in the development of customized solutions that are precisely tailored to your technical requirements.
