CAR(S) are check valves for UHP, HP and Cryogenic gases. The check valves benefit from a replaceable spring and plug. They are ideally suited for pure and ultra pure gases, combustible gases, oxidizing gases, toxic and corrosive gases, radioactive gases and noble gases.
Key advantages
100% Helium leak test performed on all valves
Individual serial number for full traceability
Electropolished surface roughness
100% degreased for Oxygen use
Cryogenic extension available
