The Guang Style Ball Valve is a common industrial valve evolved from a plug valve, featuring a spherical closing element. It achieves opening and closing by rotating the ball 90 degrees around the stem axis, primarily used for cutting off, distributing, and changing the flow direction of media in pipelines. Guang Style Ball Valves are widely applied in various industrial sectors such as petroleum, chemical, metallurgy, light industry, papermaking, power plants, and refrigeration due to their low fluid resistance, simple structure, good sealing performance, and convenient operation, making them a key device for fluid control.
