Funcation description:
Ball valve is a form of quarter-turn valve which uses a hollow, perforated and pivoting ball (called a "floating ball") to control flow through it. It is open when the ball's hole is in line with the flow and closed when it is pivoted 90-degrees by the valve handle. The handle lies flat in alignment with the flow when open, and is perpendicular to it when closed, making for easy visual confirmation of the valve's status.
Ball valves are durable, performing well after many cycles, and reliable, closing securely even after long periods of disuse. These qualities make them an excellent choice for shutoff applications, where they are often preferred to gate and globe valves, but they lack their fine control in throttling applications.

1. The fluid resistance is small, its resistance coefficient with section of equal length.
2. Simple structure, small volume, light weight.
3. Compact and reliable, the gate valve sealing surface of materials widely used plastic, sealing is good, have been widely used in the vacuum system.
4. Easy to operate, open and dose quickly, from open to close just rotate 90°, is advantageous for the remote
control.
5. Easy maintenance structure is simple, sealing ring, which generally remove replacement is more convenient
6. In the fully open or fully closed, the valve body and seat sealing surface and the dielectric isolation, medium through, does not cause the valve sealing surface erosion.
7. Applicable scope is wide, size trom small to several millimeters, big to a few meters, from high vacuum to high pressure can be applied, the ball rotate 90 degrees, in the inlet and outlet should be completely present spherical, thereby cutting flow.
