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.
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
