Fluid resistance small, the drag coefficient with the same length of pipe. |||

Compact structure, beautiful appearance, light weight. |||

Close and reliable, the current valve sealing surface material widely used plastic, good sealing performance, in the vacuum system has also been widely used. |||

Convenient operation, rapid opening and closing, from fully open to fully closed as long as the rotation 90 °, facilitate remote control. |||

Ball valve has the advantages of simple structure, convenient repair, seals are generally activities, the removal of the replacement is more convenient. |||

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