Features

1. The fluid resistance is small, and its resistance coefficient is equal to the pipe section of the same length.

2. Simple structure, small size and light weight.

3. Tight and reliable, the sealing surface material of ball valve is widely used in plastic, with good sealing performance, and it has been 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. Convenient maintenance, simple structure of ball valve, sealing ring is generally mobile, easy to remove and replace.

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

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