Double Eccentric Butterfly Valve

The double eccentric butterfly valve, an advancement from the single eccentric design, features a valve stem that deviates from both the butterfly plate and body center. This double eccentricity allows the plate to quickly detach from the seat upon opening, minimizing wear and extending seat life by reducing unnecessary pressure and scraping. This efficiency enables the use of metal seats, enhancing the valve's suitability for high-temperature applications.China double eccentric butterfly valve Manufacturer Tianjin Union Valve Co., Ltd
