A 6 inch butterfly valve is a type of butterfly valve with a nominal diameter of 6 inches, or approximately 150 millimeters. The 6 inch size is a common size for butterfly valves and is used in a variety of applications where a moderate to high flow rate is required.
The butterfly valve is designed by 6 inch butterfly valve manufacturer to control the flow of fluid through a pipeline by using a disc or butterfly that is mounted on a shaft and rotates to control the flow of fluid through the pipeline. When the disc is turned perpendicular to the flow direction, it blocks the flow completely. When it is turned parallel to the flow direction, the valve is fully open and allows the fluid to flow freely.
