Features

1.Low fluid resistance.

2.Simple structure, small size and light weight.

3.Tight and reliable.Two sealing surface sealing, can achieve complete sealing.It is also widely used in vacuum system.

4.Easy to operate, fast to open and close, from full open to full close as long as the rotation of 90°, easy to remote control.

5.Easy maintenance, ball valve structure is simple, the sealing ring is generally mobile, easy to remove and replace.

6.When fully open or closed, the sealing surface of the ball and valve seat is isolated from the medium, and when the medium passes through, it will not cause erosion of the sealing surface of the valve.

7.Wide range of application, diameter from a few millimeters to a few meters, from high vacuum to high pressure can be applied.

8.Because the ball valve has wipes during opening and closing, it can be used in the medium with suspended solid particles.
