タイトルまたは説明

1. Fluid resistance is small, and its drag coefficient is equal to that of the same length of pipe.

2. Simple structure, small size, light weight.

3. It is tight and reliable. At present, the closed cover material of the gate valve is widely used in plastics, sealability is good, and it is also widely used in vacuum systems.

4. Convenient operation, rapid opening and closing, from full to full off as long as the rotation of *0 degrees, easy to remote control.

5. Convenient maintenance, simple gate valve structure, sealing rings are generally active, demolition and replacement are relatively convenient.

6. When fully open or closed, the close cover of the sphere and seat is separated from the medium. When the medium passes through, it will not cause erosion of the closed cover of the valve.

7. Applicable to a wide range of sizes, from small to a few millimeters, to a few meters, from high vacuum to high pressure can be applied.
