Ball Valve can be rotated 90 degrees and tightly closed with small torque. The inner cavity of the valve is completely equal, providing less resistance and a straight flow path for the medium. The national standard flange ball valve itself is compact in structure and easy to operate and maintain. The flange ball valve is suitable for general working media such as water, solvents, acids and natural gas, and is also suitable for media with harsh working conditions such as: oxygen, hydrogen peroxide, methane, ethylene. The valve body can be integrated or combined.

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

Advantages of national standard flange ball valve:

1. Small fluid resistance, full-hole ball valve basically has no flow resistance.

2. Simple structure, small size and light weight.

3. Tight 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. Easy to operate, quick opening and closing, only need to rotate 90° from fully open to fully closed, which is convenient for remote control.

5. Easy maintenance, the ball valve has a simple structure, and the sealing ring is generally removable, which is convenient for disassembly and replacement.

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

7. The diameter ranges from a few millimeters to several meters, with 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.
