The main characteristics of the high-pressure ball valve are compact structure, reliable sealing, simple structure and convenient maintenance. The sealing surface and spherical surface are usually closed, not easy to be eroded by media, easy to operate and maintain. It is suitable for general working media such as water, solvent, acid and natural gas, and also suitable for media with poor working conditions, such as oxygen, hydrogen peroxide, methane and ethylene. The industry is widely used. The ball valve body can be integral or combined.
Advantages of high-pressure 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 lightweight.
- 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 valve sealing surface will not be caused.
- 7. It has a wide range of applications, ranging from small diameter to several millimetres and large diameter to several meters, 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 in the process of opening and closing.
