WEIZIDOM Eccentric Metal-Seated Butterfly Valve Selection & Installation Guide
The eccentric metal-seated butterfly valve is a high-performance valve that utilizes an eccentric structural design combined with a metal-to-metal sealing pair. It is suitable for medium to high-pressure, high-temperature, and high-sealing-requirement working conditions. The sealing form typically involves metal-to-metal contact (e.g., stainless steel + hard alloy), or metal to flexible alloy coating, offering excellent wear and temperature resistance.
