High-pressure internal threaded ball valve is the closing member is a ball, the ball rotates around the centerline of the valve body to open, close a valve. In the pipeline is mainly used to do cut off, distribution and change the direction of flow of media. Two-piece ball valve, three-piece ball valve, is widely used in recent years a new type of valve, this valve is generally installed horizontally. Mainly used for nominal pressure PN64 ~ 320, nominal size DN 8 ~ 50 high-pressure, small-diameter pipeline, used to cut off the flow of water and change the distribution of water or for the need to quickly open and close the place.

1、Small flow resistance;

2、Simple structure;

3, small size, light weight;

4, the current ball valve sealing surface material selection of plastic, good sealing;

5, easy to operate, open and close quickly, easy to control from a distance;

6, easy maintenance, the seal is generally active, easy to disassemble and replace;

7, fully open or fully closed, the ball and the sealing surface of the valve seat and the media isolation, the media through will not cause the valve sealing surface erosion.
