If a soft seal at the center line is used, is fluororubber more suitable or is silicone more appropriate? . . Which one, please answer.
Just to add. . . The medium is steam at 150 degrees
Based on the temperature range you provided, both silicone rubber and fluororubber can be used. Fluororubber has a higher temperature resistance than silicone rubber.
Silicone rubber should be used. But in the long run, it is better to use specialized ventilation butterfly valves. Such as the D371W type. The valve body is generally welded, allowing for a certain amount of leakage. It is also possible to have a professional butterfly valve manufacturer remove the rubber seals from commonly used D371X type butterfly valves and adjust the size of the butterfly disc. It works pretty well.
The fan doesn’t have any specific requirements regarding leakage; if you need to choose, either type of rubber will work
