1. The fluid resistance is small, and its resistance coefficient is equal to the pipe section of the same length.
2. Simple structure, small size and light weight.
3. It is tight and reliable. At present, the sealing surface material of the gate valve is widely used in plastic and has good sealing performance.
It has also been widely used in vacuum systems.
4. Easy operation, fast opening and closing, only need to rotate 90 ° from fully open to fully closed, which is convenient for remote control.
5. Convenient maintenance, simple gate valve structure, seal ring is generally movable, and it is more convenient to disassemble and replace.
6. When fully open or fully closed, the sealing surfaces of the ball and valve seat are isolated from the medium, and the medium will not cause erosion of the valve sealing surface when the medium passes.
7. Wide range of applications, from small diameter to several millimeters, large to several meters, from high vacuum to high pressure can be applied.
