It is widely used in oil refining, long-distance pipelines, chemical industry, papermaking, water conservancy, municipal administration and other fields. Due to the different types of various fluid media passing through the ball valve, some fluid media contain impurities such as silt and suspended matter. During long-term use, impurities may accumulate inside the valve body, eventually causing the ball valve to be blocked, causing inconvenience.
