Bellows high pressure valve for HP, UHP, cryogenic gases and fluids – HP9000

HP9000 is a stop globe valve with replaceable bellows sealing. The valve is dedicated to high pressure at cryogenic temperature and can be actuated by a manual handwheel or a pneumatic actuator. It is ideally suited for liquid nitrogen and liquid oxygen, vacuum, 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, noble gases or liquids.

Key advantages

100% Helium leak test performed on all valve
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
