1.Fluid resistance small, the resistance coefficient and the length of the pipeline section with equal. 2. Simple structure, small volume, light weight.
3. Close reliable, at present the ball valve seal face materials widely used plastic, good sealing, vacuum system also in has been widely used.
4. Easy operation, open and close rapidly, from full open to all as long as 90 ° rotation, facilitate remote control.
5. Easy maintenance, ball valve structure simple, sealing ring is usually activities, remove the change are more convenient.
6. In the fully open or fully closed, the ball and seat sealing surface and medium isolation, media through the, won't cause of valve sealing surface erosion.
A wide range, from a few millimeters to size, big to several meters from the high vacuum and high pressure can apply.
The ball rotates 90 degrees, in the exit into, shall all be present the sphere, and truncated flow. |
