Hard-sealed ball valve for coal chemical industry

I would like to ask those of you who have practical experience using ball valves in the coal chemical industry: what aspects of design should be considered when selecting ball valves to ensure they are of good quality? Please give me some advice. Thank you!
The hard-sealed ball valves used in the coal chemical industry are mainly based on the \"three-eccentric high-temperature and high-pressure butterfly valve\" design, with most of them being manufactured by foreign companies. For example: German Gutmus, Eipolo, FLOW_sever... American Tego, etc
