Valve Micro Leakage Detection Analysis And Operational Considerations

As the global climate continues to heat up,and social awareness of environmental protection continues to increase,the valve leakage class in valve industry is also more and more demanding.It is particularly important to test valves for fugitive emission test.The current standards have regulations on fugitive emission test,but also have different requirements.The same valve and the same instrument,after different personnel test,often get different test results.This may lead to incorrect conclusions about the final test results of the valve.The main purpose of this paper is to analyze and introduce the key points of operation process of valve fugitive emission test.
