The closure part of ball valve is a ball which can rotate around the stem axis 90 degree to realize the purpose of opening and closing. Ball valve can cut off, distribute and change the direction of medium flow in the pipeline. V-port ball valve has a good flow regulation function.  

Advantages:  

1. Lowest flow resistance ;  

2. Suitable for corrosive media and low boiling point liquid；

3. Achieve fully sealing under a wide range of pressure and temperature, can achieve complete sealing;  

4. Fast opening and closing of the valve, operation is without impact;  

5. The closure ball can be automatically positioned at the boundary position;  

6. Reliably seal for both sides in the working medium;  

7. The medium through the valve at high speed will not cause the erosion of the sealing surface due to that the sealing surface of the ball and seat is isolated from the medium when fully open and closed.

8.Suitable for low temperature medium system due to its compact structure and light weight. 

9. Bear the stress from pipeline well because of its symmetrical valve body, especially the welded valve body type. 

10. The closure can withstand the high pressure difference when closing.
