I have a breather valve installed on a atmospheric tank. Originally, I specified 100% of accumulation. But Based on vendor feedback, they are asking if 105% accumulation is acceptable.
I checked API 2000. Previously in edition 1998, there was a table to mention that normal practice is 100% accumulation for direct acting breather valve. But the table was removed from API 2000 edition 2014. There is no more such statement. Can anyone advise if 105% accumulation is acceptable?
Thank you in advance.
