Feature: can be designed with a Damping Cylinder.
1. The fluid resistance is small; its resistance coefficient is a section of equal length.
2. Simple structure, small volume, light weight
3. Compact and reliable; the gate valve sealing surface is made of widely used plastic; the sealing is good; and it has been widely used in the vacuum system.
4. Easy to operate, open and close quickly, from open to close, just rotate 90°; this is advantageous for the remote
control.
5. Easy maintenance structure is simple; sealing ring, which generally remove replacements, is more convenient
6. In the fully open or fully closed state, the valve body and seat sealing surface and the dielectric isolation, medium-through, do not cause the valve sealing surface erosion.
7. The applicable scope is wide, ranging from small to several millimeters to large to a few meters. From high vacuum to high pressure, the ball can rotate 90 degrees, and the inlet and outlet should be completely spherical, thereby cutting flow.
