I’m a bit confused. Is a two-way hard-seated butterfly valve the same as a two-way hard-seated ball valve? I’m really confused...... I asked several manufacturers; some said they’re the same, while others said they’re different. The verification shows they are the same. I hope someone can help answer this
Because when searching on the web for many manufacturers, their websites use data related to ball valves; the name should be changed to two-way hard-seating butterfly valve
Personally, I think butterfly valves and ball valves are two completely different types of valves. As for what you mean by \"hard sealing\", it refers to sealing surfaces that use metal sealing rings for sealing.
Two-way hard-sealed triple-eccentric butterfly valve, used for large diameters as a replacement for hard-sealed ball valves.
I think I’ve seen this once; they look very similar on the outside, but their internal structure differs. I hope those who have relevant information can share it
They are not the same thing; butterfly valves, ball valves, and plug valves all come with hard seals!
What kind of butterfly valve is this? A two-way hard-seal butterfly valve can be installed without any direction constraints; it’s not professional – learn from other sailors*
It’s different; the appearance of a rotary ball valve is similar to that of a butterfly valve, but the structure of its sealing surfaces differs, as does its manufacturing process. Choose based on the operating conditions; their functions are almost identical. Individuals tend to use three-eccentric all-metal butterfly valves
