Ball Valve summary
Ball valve has the advantages of simple structure, quick switching, easy operation, small volume, light weight, few parts, least fluid resistance and good tightness.
Ball Valve scope of application
1. Suitable for medium with low temperature (≤150℃), high pressure and high viscosity;
2. Can not be used for flow regulation;For situations requiring quick opening and closing;
3. Usually, the ball valve is recommended to be used in the pipeline with two-position regulation, strict sealing performance, wear, shrinkage channel, rapid opening and closing action, high pressure cut-off (large pressure difference), low noise, gasification phenomenon, small operating torque and small fluid resistance;
4. Also suitable for light structure, low pressure cut-off, corrosive medium;
