Q947Y natural gas high pressure ball valve

The ball valve is a new type of valve that has been widely used in recent years. It has the following advantages:

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

2. Simple structure, small size and light weight.

3. It is tight and reliable. At present, the sealing surface material of the ball valve is widely used in plastics with good sealing performance, and it has also been widely used in vacuum systems.

4. Convenient operation, rapid opening and closing, only need to rotate 90° from fully open to fully closed, which is convenient for remote control.

5. Convenient maintenance, simple structure of the ball valve, the sealing ring is generally movable, it is convenient to disassemble and replace.

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

7. It has a wide range of applications, with a diameter ranging from a few millimeters to a few meters, and can be applied from high vacuum to high pressure. When the ball rotates 90 degrees, it should show a spherical surface at the entrance and exit, so as to cut off the flow.
