3 PC forged steel ball valve and gate valve is belong to one type of valve, the difference in its closure is a ball, a sphere around the center line of the body as a rotation to achieve a kind of open and close the valve. Ball valve in the line is mainly used for cutting, distribution, and change the flow direction of medium. Three type ball valve is widely used in recent years a new type of valve, the valve average installation.

A, three chip forged steel ball valve has the following advantages:

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 widespread use of plastic ball valve sealing surface of materials, good sealing, also has been widely used in the vacuum system.

4. Easy to operate, open and close quickly, from open to close just rotate 90 °, is advantageous for the remote control.

5. Easy maintenance, simple structure of ball valve, sealing ring, which generally remove replacement is more convenient.

6. In the fully open or fully closed, the ball and seat sealing surface and the dielectric isolation, medium through, can not cause the valve sealing surface erosion.

7. Applicable scope is wide, size from small to several millimeters, big to a few meters, from high vacuum to high pressure can be applied.
