Differences in valve standards
Thread Content
Dear experts, I would like to ask: what are the differences between API600 and API60M, API602 and API602M, and API603 and API603M in the application standards for American standard valves? Thank you! ! !
There are so many material types for pipes that I’ve never really understood them; I’m here to learn about it**
The standard content is the same; the version with an M indicates that the units used are metric, while those without an M use imperial units
Is there a source for what you mentioned? Thank you
