Are there any standards for globe valves larger than 4 inches in the API?
Thread Content
I recently learned a bit about API standards, and found that the only one related to globe valves is API602; however, this standard applies to valves with a nominal diameter of 4 inches or less. I’m not sure which standard applies to globe valves larger than 4 inches; I hope someone with more knowledge can advise me.
API623 Steel Globe Valves – Flanged and Buttwelding Ends, Bolted Bonnets. It covers valves with nominal pipe sizes of NPS: 2, 21/2, 3, 4, 6, 8, 10, 12, 14, 16, 18, 20, 24; globe valves with a size of ≥DN50
API600 is also applicable to globe valves!
