1. The flow resistance is small and the resistance coefficient is equal to the same length of pipe.
2. Simple structure, small size, light weight. Electric cut-off valve
3. Close and reliable, gate valve sealing surface materials widely used plastic, good sealing, in the vacuum system has been widely used.
4. Easy to operate, open and close quickly, from open to full off as long as the rotation of 90 °, easy to control long-distance.
5. Convenient maintenance, simple structure of the gate valve, sealing ring is generally active, disassembly and replacement is more convenient.
6. In open or full closed, the ball and valve seat sealing surface and media isolation, media through, will not cause the valve seal surface erosion.
7. Wide range of application, path from small to several millimeters, large to a few meters, from high vacuum to high pressure can be applied.
