The main advantages of cemented carbide ball valves can be divided into the following aspects:
Applicable occasions for several common carbide ball valves:
1. In the double position adjustment, it is suitable for the sealing performance, high opening and closing (1/4 turn opening and closing), large pressure difference, small operating torque, small flow resistance, cavitation or vaporization. Use a carbide ball valve;
2. In a pipeline with a corrosive medium;
3. In a low temperature cryogenic device or a high temperature and high pressure pipeline system;
4. Full-diameter welded carbide ball valve can be used in oil pipelines and gas pipelines to be buried underground;
5. Specially designed V-shaped open structure carbide ball valve can also have certain adjustment functions.
