Ball valve opens by turning a handle attached to a ball inside the valve. The ball has a hole, or port, through the middle, so that when the port is in line with both ends of the valve, flow will occur. When the valve is closed, the hole is perpendicular to the ends of the valve, and flow is blocked. The ball, which can make a quarter turn (90) around the spin axis, is the on/off control of the Ball valve. Ball valves in the piping are used to cut, distribute and change the flow direction of the fluid. If the opening were designed to be V-shaped, it would also have the excellent function of flow control. Ball valves, which need a little rotating force and turn a quarter, can be closed tightly. The completely equal lumen provides a littler-resistance "green passage". Ball valve not only has the advantages of simplicity in system structure and good performance in sealing Properties, but also smaller in size, less in weight, less material, smaller dimension, less drive torque, easy-operating, easy-repaired, can be applied to general media, such as water, solvent, acid and natural gas. It still can be used in poor working conditions, such as oxygen, hydrogen peroxide, methane, ethylene and so on. The body of ball valves can be a whole or a combined one. Ball valves are widely used, the demand of quantity is still growing up, and the current trend is to develop high-temperature, high pressure, heavy caliber, high tightness, long life-span, excellent adjusting performance and multi-function valves. The reliability and other performance indexes are all reached a comparable high level, and ball valves have partly replaced gate valves, globe valves and throttle valves. Due to the outstanding advantages of the ball valves, it has been widely used in the areas of aerospace, Petroleum, long-distance pipeline, light industry and food industry, construction and so on.
