Features

(1) small fluid resistance, full-diameter ball valve basically no flow resistance.

(2) Simple structure, small size, light weight.

(3) close and reliable. It has two sealing surfaces, and the ball valve sealing surface material widely used in a variety of plastic, good sealing, can achieve a complete seal. In the vacuum system has also been widely used.

(4) easy to operate, open and close rapidly, from full open to full close as long as 90 ° rotation, easy to remote control.

(5) easy maintenance, ball valve structure is simple, the seals are generally active, demolition and replacement are more convenient.

(6) In the fully open or fully closed, the sealing surface of the ball and the valve seat is separated from the medium, and the passage of the medium will not cause the erosion of the valve sealing surface.

(7) a wide range of applications, the path from small to a few millimeters, up to a few meters, from high vacuum to high pressure can be applied.

(8) The ball valve can be used in the medium with suspended solid particles because the ball valve is wiping during opening and closing.
