Butterfly valve is a 90 degree switch valve that is driven by the valve stem to rotate the disc plate. It is widely used in clean pipelines such as food, medicine, chemical industry, industrial environmental protection, water treatment, high-rise buildings, and water supply and drainage pipelines for opening and closing or regulating medium flow. In the process of continuous research and development, butterfly valves are also classified into many types and applied to different working conditions. Butterfly valves can be divided into hard sealed butterfly valves and soft sealed butterfly valves according to their sealing forms. Soft sealed butterfly valves are mainly used in water treatment, weakly acidic and alkaline media, and low-temperature and low-pressure environments. Hard sealed butterfly valves can be used in high-temperature and high-pressure environments. Suitable materials can be ourphped based on the properties of different media.

The three eccentric metal hard sealed butterfly valve utilizes an elastic stainless steel sealing ring installed on the valve body to achieve true zero leakage, and is generally used in high-temperature and medium with particles and other working conditions.
