China Straight-Through Type Pneumatic O-Type Ball Control Valve, Find details about China PVC Ball Valve, Hot Sell from Straight-Through Type Pneumatic O-Type Ball Control Valve
1. The fluid resistance is small, and its resistance coefficient is equal to the pipe length of the same length. |
2.Tight and reliable. At present, the sealing surface material of the ball valve is widely used in plasyics and has good sealing performance. It has also been widely used in vacuum systems. |
3. Easy operation, quick opening and closing, as long as it is rotated 90o from full opening to full closing, which is convenient for long-distance control. |
4. Easy maintenance, simple structure of the ball valve, the sealing ring is generally active, and it is convenient to disassemble and replace. |
5. When fully open or fully closed, the sealing surface of the ball and the seat is isloated from the medium, and the medium will not cause erosion of the sealing surface of the valve. |
6. Wide range of applications,from small to a few millimeters, up to a few meters. from high vaccum to high pressure can be applied. |
