The national standard flange ball valve can rotate 90 degrees and close tightly with a small torque. The inner cavities of the valve are completely equal, which provides a small resistance and a straight flow path for the medium. The national standard flanged ball valve itself has a compact structure and is easy to operate and maintain. Flanged ball valves are suitable for general working media such as water, solvents, acids and natural gas, as well as media with harsh working conditions, such as oxygen, hydrogen peroxide, methane, and ethylene. The valve body can be integrated or combined.

The national standard flange ball valve is compact in structure, easy to operate and maintain, suitable for general working media such as water, solvent, acid and natural gas, and has harsh working conditions (such as hydrogen peroxide), and is also suitable for media. Ball valve bodies such as methane and ethylene can be integrated or combined. Such valves should be installed horizontally in the pipeline.

Advantages of national standard flanged ball valve

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

2. Simple structure, small size and light weight.

3. Close and reliable. There are two sealing surfaces. The current ball valve sealing surface materials are widely used in various plastics, and have excellent sealing performance, which can achieve complete sealing. It is also widely used in vacuum systems.

4. Convenient operation, fast 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, and generally movable sealing ring, which is easy to disassemble and replace.

6. When fully opened or fully closed, the sealing surface of the ball and the valve seat is isolated from the medium. Even if the medium passes through, the valve sealing surface will not corrode.

7. The diameter ranges from several millimeters to several meters, and it has a wide range of applications, and can be used under high vacuum to high pressure.

8. Because the ball valve has wiping characteristics when opening and closing, it can be used for media with suspended solid particles.
