Product Features

1. Since the ball valve can be wiped in the process of opening and closing, it can be used in the medium with suspended solid particles.
2. The flow resistance is small, and the ball valve with full diameter has no flow resistance.
3. It has the advantages of simple structure, small volume and light weight.
4. Tight and reliable. It has two sealing surfaces. At present, the sealing surface materials of ball valves are widely used with various plastics, which has good sealing performance,
5. Complete sealing can be achieved. It has been widely used in vacuum system.
6. Wide range of application, diameter from small to a few millimeters, large to several meters, from high vacuum to high pressure can be applied.
7. It is easy to operate and quick to open and close. Only 90 ° rotation is needed from full opening to full closing, which is convenient for remote control.
8. Maintenance is convenient, ball valve structure is simple, seal ring is generally movable, disassembly and replacement are more convenient.
9. When the valve is 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 valve sealing surface when the medium passes through.
