Medical check valve CAR(S)

medical gasgrey

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 Specifications Fluid media Standard, high and ultra high purity and corrosive gases or liquids Max. working pressure see table below Pneumatic actuator operating pressure Temperature range 77.15 K to 523.15 K (-196°C to +250°C)* Flow capacity (cv) Nominal seat diameter see table below Certified max. helium outboard leak rate (at max. pressure) ≤ 1.10-10 Pa.m3 .s-1 Certified max. helium across the seat leak rate (at max. pressure) - ≤ 1.10-6 Pa.m3 .s-1*
