SCH8O/DIN Electric Flange Ball Valve

The defining feature of the electric flange ball valve is that its closure component (the ball) rotates around the stem’s axis, typically enabling valve opening or closing through a 90° rotation. It boasts sealing performance, high flow capacity, low flow resistance, simple structure, easy maintenance, and long service life. The valve body’s passage is of the same diameter as the connected pipeline, allowing the medium to flow through almost without loss. Therefore, it is often used in applications requiring stringent sealing, such as controlling gases, liquids, steam, and media containing fibrous impurities. electric flange ball valves are widely applied in industries like petroleum, chemicals, metallurgy, light industry, papermaking, power plants, and refrigeration. Particularly, they are commonly used as emergency shut-off valves in oil depots, chemical facilities, and gas tank pipelines. In emergencies, such as fires caused by oil or hazardous material leaks to power outages, the electric flange ball valve automatically shuts off without manual operation, effectively preventing secondary accidents, reducing property damage, and safeguarding personnel safety.
