<span style="color: rgb(119, 119, 119); font-family: "Open Sans", Arial, sans-serif; font-size: 16px;">The three eccentric laminate hard seal flange butterfly valve is a durable and energy-efficient valve, designed for long-lasting performance. It features a three-dimensional core principle design, with a valve seat made from a laminated structure of stainless steel and graphite, combining both hard and soft sealing properties for optimal performance. The valves main components include the valve body, butterfly disc, laminated seal valve seat, valve stem, and transmission mechanism, all crafted with precision and advanced technology. This versatile valve is widely used in industries such as metallurgy, electric power, petroleum, chemicals, and in air, gas, combustible gas, and water supply and drainage pipelines.</span><br style="box-sizing: border-box; color: rgb(119, 119, 119); font-family: "Open Sans", Arial, sans-serif; font-size: 16px;" />

<span style="box-sizing: border-box; font-weight: 700; color: rgb(119, 119, 119); font-family: "Open Sans", Arial, sans-serif; font-size: 16px;">Triple Eccentric Butterfly Valve - Features</span><br style="box-sizing: border-box; color: rgb(119, 119, 119); font-family: "Open Sans", Arial, sans-serif; font-size: 16px;" />

<span style="color: rgb(119, 119, 119); font-family: "Open Sans", Arial, sans-serif; font-size: 16px;">The three eccentric (offset) design features three distinct offsets that enhance the valves performance. The first offset occurs when the shaft is positioned away from the centerline of the sealing face. The second offset involves the shaft being deviated from the centerline of the pipe and valve. The third offset is the unique angle between the oblique taper of the eccentric seat and the centerline of the pipe, ensuring that the seat completely disengages from the sealing ring during the entire opening and closing process. This design leverages the cam effect, effectively eliminating the risk of abrasion and leakage.</span> |
