A double eccentric butterfly valve DN1200 is a type of butterfly valve with a nominal diameter of 1200 millimeters. The DN1200 size is quite large and is commonly used in industrial processes where a high flow rate is required.
The double eccentric butterfly valve is designed by double eccentric butterfly valve DN1200 factory to provide precise control over the flow of fluids in large pipelines. It features a disc, or butterfly, that is mounted on a shaft and rotates to control the flow of fluid through the pipeline. The double eccentric design means that the disc is offset from the centerline of the valve seat, which reduces the friction between the disc and the seat and allows for a tighter seal against leakage.
