Advantages of q41f-16 cast iron ball valve:

1. The fluid resistance is small, and the ball valve with full bore basically has no flow resistance.

2. Simple structure, small volume and light weight.

3. Tight and reliable. It has two sealing surfaces. At present, all kinds of plastics are widely used in the sealing surface materials of ball valves. It has good sealing performance and can achieve complete sealing. It is also widely used in vacuum system.

4. It is easy to operate and fast to open and close. It only needs to rotate 90 ° from full open to full close, which is convenient for remote control.

5. The maintenance is convenient, the ball valve structure is simple, the sealing ring is generally movable, and the disassembly and replacement are relatively convenient.

6. When the valve is fully open or closed, the sealing surface of the ball and the valve seat shall be isolated from the medium. When the medium passes through, the corrosion of the sealing surface of the ball valve will not be caused.

7. It has a wide range of applications, ranging from small diameter to several millimeters and large diameter to several meters. It can be applied from high vacuum to high pressure.

8. The ball valve can be used in the medium with suspended solid particles due to its wiping property during the opening and closing process.
