The opening and closing parts of the electric globe valve are plug-shaped discs, the sealing surface is flat or cone, and the disc moves in a straight line along the center line of the fluid. The movement form of the valve stem includes the lifting stem type (the valve stem is lifted and lowered, the handwheel does not rise), and there is also the lifting and rotating stem type (the handwheel rotates and lifts together with the valve stem, and the nut is set on the valve body). The motorized globe valve is only suitable for full opening and full closing, and does not allow adjustment and throttling.
