1. The fluid resistance is small, and its resistance coefficient is equal to that of pipe sections with the same length.

2. Simple structure, small volume and light weight.

3. Tight and reliable, the sealing surface material of gate valve is widely used in plastic, with good sealing performance, and has also been widely used in vacuum system.

4. It is easy to operate and can be opened and closed quickly. Only 90 ° rotation is required from full opening to full closing, which is convenient for remote control.

5. It is easy to maintain, the gate valve is simple in structure, the sealing ring is generally movable, and it is convenient to remove and replace.

6. When the valve is fully opened or closed, the sealing surfaces of the ball and valve seat are isolated from the medium. When the medium passes through, it will not cause erosion of the valve sealing surface.

7. It is applicable to a wide range of applications, ranging from a few millimeters to several meters in diameter, from high vacuum to high pressure.
