Bellows low to high pressure valve for HP, UHP, cryogenic gases and fluids – K900 — manufacturer product image

K900 is a stop globe valve with replaceable bellows sealing. It is dedicated to low pressure at cryogenic temperature and can be actuated by a manual handwheel or a pneumatic actuator. The valve is ideally suited for liquid nitrogen and liquid oxygen, pure and ultra pure gases or liquids, combustible gases or liquids, oxidizings gases or liquids, toxic and corrosive gases or liquids, radioactive gases or liquids and noble gases or liquids.

Key features
  • 100% Helium leak test performed on all valves
  • Sustainable metallic bellows providing a high internal/ external tightness
  • Fluid specific seat material as standard options: Metal - Metal on request
  • Visual Open-Close indicator for both manual and pneumatic versions
  • Individual serial number for full traceability
  • Corrosion resistant internal option available: Hastelloy® bellows
  • Electropolished surface roughness
  • 100% degreased for Oxygen use
  • Cryogenic extension
