what's the differences of American standard valve standard and Europe valve standard.Like API598 and ISO5208 , EN12266 valve inspection standard, or API600 valve design manufacture standard,and EN598,
the name itself suggest that it isn't. BSP covers only pipelines but ISO is a standard concerning different materials, processes, programs and quality policies.
This Site Might Help You. RE: Is valve standard of API and ISO same? what's the differences of American standard valve standard and Europe valve standard. Like API598 and ISO5208 , EN12266 valve inspection standard, or API600 valve design manufacture standard,and EN598,
It is hard to say generally. Each valve standard will cite other relevant standards, so it is API system and ISO system. Usually it has some differences between API and ISO valve, but it is similar. Most time the design Principal is same, the structure of valve is similar. For example , API swing check valve, it has an hanging system without bolt outside of body, but DIN swing check valve has an bolt for stem. The dimension obviously is different, API calculated by inch, but ISO usually use metric unit. Of course it can be transformed to same dimension. Below is some API standard, and ISO or DIN Standard. We are just able to discuss this topic for specific standard. For API598 and ISO 5208, in my opinion, it is a little different, but in fact, the differences is not very big, if an valve able to pass API598, usually same for ISO 5208. Same for ISO5208 to API 598.
