Are there ball valves that can withstand temperatures of 1000–1200 degrees Celsius?

The medium is flue gas; pressure: 0.15–0.2 MPa, flange-connected
Don’t even think about domestic options; it’s good enough if it’s available abroad. Are the sealing requirements high? What’s the pressure? High-temperature flue gas is usually handled with butterfly valves, but your diameter is too small
We can provide a solution, but it won’t be cheap either. :lol
Low-pressure valves that can withstand 1200 DEG C do exist, but I have not seen ball valves of this kind. If the process is improved, it is entirely possible to reduce the temperature below 200 DEG C before the valve.
At such high temperatures, isn’t welding used? Can flanges still be used?
You are referring to a hard seal with cooling water for temperature reduction
Please introduce this method; my idea is not like this. Haha
1200 degrees Celsius, what materials can withstand it? I think it’s 1000–1200°F; could the temperature unit be wrong? It’s probably around 650 degrees Celsius, and a hard-sealed ball valve can handle such conditions
Please don’t water it, dude. More people are welcome to join in the discussions
I think your guess makes sense; at this temperature the metal is red-hot and phase transformation is beginning to occur
