Double eccentric butterfly valve
Double eccentric butterfly valve, also known as high-performance butterfly valve, is mainly composed of valve body, valve plate, valve core, seat, valve cover, support rod, shaft head, cover, detector, gasket body and other components. Its structural feature is that the valve stem axis deviates from the center of the butterfly plate, but also deviates from the center of the body, this double eccentric design makes the valve after opening the butterfly plate can be quickly removed from the seat, greatly eliminating the unnecessary excessive squeezing and scratching phenomenon between the butterfly plate and the seat.
