Leak testing high pressure valves Testing the leakage rate of a high pressure valve of the type used in natural gas filling station pumps or in connection with hydrogen transport, for example, is a challenging task. To assure that no hydrogen can escape from the valve, it has to have a very low leakage rate of not more than 1·10 -6 mbar l/sec. By comparison: These leakage rate ranges differ very significantly from the leakage rates that enabl
