Double cylinder double disc gate valve adopts the double-gate structure, the opening and closing distance of the valve is short, the opening and closing is faster, the ram is less worn, and the service life is long.The valve has simple structure, flexible operation, light weight and no jamming. It is especially suitable for the transportation and flow adjustment of all kinds of non-viscous solids and grain materials. The installation is not limited by the angle, the operation is convenient, and the opening can be adjusted at any time.Mainly used in the roof, bottom, import and export of papermaking, building materials, metallurgy, mining, electric power, chemical industry, glass, light industry, grain and other industries. It is an ideal device that adapts to large changes in control flow, frequent starts, and can be quickly cut off.
