Main features: Between the opening and closing of the valve, the sealing surface of the butterfly plate gradually deviates, squeezing the sealing surface of the valve seat, thereby reducing mechanical abrasion and damage between the sealing surface of the butterfly plate and the sealing surface of the valve seat. For double eccentric butterfly valves, when the butterfly plate rotates 8 to 12 degrees, the sealing surface of the butterfly plate will completely leave the sealing surface of the valve seat, thereby reducing mechanical abrasion. As it can effectively reduce mechanical scratches, the sealing performance and service life will be effectively enhanced.
