What are the characteristics of ball valve widely used
Ball valve is a new type of valve which came out in 1950s. In a short period of more than 30 years, it is one of the valve varieties that have developed rapidly in recent ten years. It is mainly used to cut off, distribute and change the flow direction of medium in pipeline. The ball valve with V-shaped opening also has good flow regulation function. The ball valve can be closed tightly with 90 degree rotation and small rotation torque. The completely equal inner cavity of the valve body provides a small resistance and straight passage for the medium. The ball valve not only has simple structure and good sealing performance, but also has small volume, light weight, less material consumption, small installation size, small driving torque, simple operation, easy to realize quick opening and closing, easy operation and maintenance within a certain nominal diameter range. 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 valve body of ball valve can be integral or combined.
