What material is the seat seal ring of the ball valve Q41S-25P? Why can its operating temperature reach 300°C?

In JB T308, S refers to plastic; I have never encountered valves with such a type of sealing surface – sewage treatment should use this material

In terms of model, S stands for plastic; for PEEK, 300 degrees for a short period is no problem. As for the exact material used, it’s necessary to verify this with the manufacturer
