First, the characteristics of high temperature ball valve

 1, simple structure, small size, light weight, 
 2, close and reliable. It has two sealing surfaces, and ball valve sealing surface material widely used in a variety of plastic, good sealing, can be completely sealed. In the vacuum system has also been widely used. 
 3, easy to operate, quickly open and close, as long as the full turn to 90 degrees off, easy to remote control. 
 4, easy maintenance, ball valve structure is simple, the seals are generally active, demolition and replacement are more convenient. 
 5, in the fully open or fully closed, the sealing surface of the ball and valve seat and media isolation, the media will not cause erosion of the valve sealing surface. 
 6, because the ball valve in the opening and closing process wipe, it can be used for medium with suspended solid particles. 
 7, small fluid resistance, the whole diameter of the ball valve basically no flow resistance.
