PR is used high strength new material, which has features of hydrogen brittleness resistance, corrosion resistance, and cycle life is not less than 50000 times.

Design optimization to lightweight, the whole valve weight is below 650g;

High airtightness, potential hydrogen leakage is reduced, less than 0.6Nml/h leakage rate;

Coaxial multistage pressure reducing ensures the structure stability, and the PR integrated high pressure diverter, two stage pressure reducing module, check valve, unloading valve module and so on；The two stagepressure regulator structure ensures the output pressure accuracy and stability;
