Introduction to Double Offset Butterfly Valve
A double offset butterfly valve, also known as a high – performance butterfly valve, is a type of quarter – turn valve used to regulate the flow of fluid in a pipeline. It gets its name from the two offsets incorporated in its design. The first offset is of the valve shaft from the center of the disc, and the second offset is from the centerline of the pipe. Double Offset Butterfly Valve
This double – offset design offers several advantages. Firstly, it reduces friction between the seat and the disc during valve operation, which significantly extends the valve’s service life. Secondly, it provides better sealing performance compared to a single – offset or concentric butterfly valve, especially in high – pressure and high – temperature applications. Double offset butterfly valves are widely used in various industries such as oil and gas, power generation, water treatment, and chemical processing.
