Triple eccentric 6 butterfly valve is a type of industrial valve which is designed to control the flow of fluids in pipelines. 6 wafer butterfly valve is called "triple eccentric" because its sealing surface is not centered, but rather is offset from the center line of the valve's disc. This unique design allows for a tight seal even in high pressure and high temperature applications.
The valve's body is typically made of stainless steel or other corrosion-resistant materials, and the disc is composed of a metal or elastomer coating. It has a high-performance sealing system consisting of a metal seat ring and a laminated seal ring.Triple eccentric butterfly valves are used in a wide range of industries, including oil and gas, chemical, power generation, and water treatment. They are ideal for controlling the flow of viscous liquids, gases, and slurries. Their benefits include increased reliability, decreased maintenance, and improved energy efficiency.
