Compared with the soft seal ball valve, the metal hard seal ball valve can adapt to a wider range of temperature and fluid medium fields. Under the working condition, the seal is safe and reliable, the service life is long, the operation is convenient, and the Pressure loss is small. The main applications are in high-temperature, high-pressure, highly corrosive and granular media containing working conditions, such as coal chemical, polycrystalline silicon, sulfuric acid/nitric acid and other industries.
