What is the difference between D343H-16P and D343W-16P, D343F-16P?
Thread Content
I have been working in production management and haven’t paid attention to valve models. I’d like to ask gently: what are the differences between D343H-16P, D343W-16P, and D343F-16P?
Take a close look at the valve manual; it contains detailed instructions. The difference among these three models lies only in the material of the sealing surface or lining: D343H-16P uses Cr13 series stainless steel, D343W-16P features a seat sealing surface made from material that is processed directly from the valve body itself, and D343F-16P uses fluoroplastic

D343H-16P must be a mistake; how could a valve made of 304 material have a sealing surface made of 13CR?
There’s a problem: it seems that there isn’t yet a butterfly valve of the model D343F-16P. Multi-layer butterfly valves can only be designed with a hard seal, right? They can be made as double-eccentric types, and in that case the model would be D342F
