API 600 vs API 623: Globe and Gate Valve Standards
Gate valves are governed by API 600, while check valve design is covered in API 594. Prior to the release of the new standard API 623, it was common in the refining and petrochemical industries to reference the API 600 wall thicknesses for globe valves on specification sheets, even though API 600 only applied to gate valves.
