1, The flow resistance is small. The medium passage of the valve body is straight through, the medium flows in a straight line, and the flow resistance is small.

2. It is more labor-saving when it is opened and closed. Compared with the globe valve, the movement direction of the gate is perpendicular to the flow direction of the medium, whether open or closed.

3. The height is high and the opening and closing time is long. The opening and closing stroke of the gate is large, and the lifting is carried out by screw.

4, Water hammer phenomenon is not easy to produce. The reason is that the closing time is long.

5, The media can flow in any direction on both sides, easy to install. The two sides of the gate valve are symmetrical.

6, The length of the structure (the distance between the connecting ends of the shell two) is small.

7, The shape is simple, the structure length is short, the manufacturing process is good, the application scope is broad.
