Bellows valves for Cryogenics gases and liquids

High-Performance bellows Valves for cryogenic gases and liquids

Cryogenic valves are specially designed for use at extremely low temperatures. These valves are indispensable in industries where gases such as hydrogen, oxygen, nitrogen and argon must be handled at cryogenic temperatures in order to:

  • store and transport gas more efficiently
  • use in industrial refrigeration and food preservation
  • supply energy in large quantities

Rotarex offers a range of bellows valves specially designed for:

  • Withstand extreme temperatures down to -270°C
  • Withstand high pressures up to 240 bar

Each valve requires certain adaptations to deliver optimum performance under specific conditions. Whatever your needs, Rotarex has you covered.
