How to choose sanitary ball valve for pure steam pipeline or diaphragm valve

Is it better to use a sanitary ball valve for pure steam pipelines or a diaphragm valve? How to choose a sanitary ball valve for pure steam pipelines or a diaphragm valve? How to choose a pure steam quality standard is the same as that of water for injection. There are stagnant areas and dead corners at the center of the ball valve. It is recommended It is easy to fail to close when replacing the sanitary ball valve, and the steam on the spherical surface cannot be flushed during disinfection. It is more reasonable to use a sanitary diaphragm valve. It is better to use a diaphragm valve. For some design institutes, it is better to use a sanitary ball valve for pure steam pipelines. Diaphragm valve is good? The quality standard of pure steam is the same as that of water for injection. There are stagnant areas and dead corners in the center of the ball valve. It is recommended to replace the sanitary ball valve, which may cause the phenomenon of unsuccessful closing, and the spherical part of the steam cannot be flushed during disinfection. It is better to use a sanitary diaphragm valve. Reasonable. It is best to use diaphragm valves. Some design institutes use ball valves when designing. This should not be regarded as misleading customers. But as a high-quality system, the cleanest and least risky diaphragm valve should be. Pure steam is used in the sterilization process, so what are the materials that need to be processed during sterilization? The ball valve has dead corners and there is a risk of microbial growth, but the sterilization process is not to kill microbes!
