Three-piece butt welding ball valve has the following advantages:
1. Fluid resistance is low, and its resistance coefficient is equal to that of the same length pipe.
2, simple structure, small volume, light weight.
3, tight and reliable, ball valve sealing surface material is widely used in plastic, good sealing, in the vacuum system has also been widely used.
4, easy to operate, open and close quickly, from fully open to fully closed as long as the rotation of 90 degrees, easy to remote control.
5, easy maintenance, ball valve structure is simple, sealing ring is generally active, disassembly and replacement are more convenient.
6. When fully open or fully closed, the sealing surface of the ball and seat is isolated from the medium. When the medium passes through, the sealing surface of the valve will not be eroded.
7, wide application range, small to a few millimeters, large to a few meters, from high vacuum to high pressure can be applied
