The ball valve has been invented in the 1950s. It’s also among the fast-developed valves in the past few decades, particularly in USA, German, Japan, France, Italy, Spain and UK where ball valves are commonly used.
Because of dedication to research and development, the stability and capacity of ball valve were able to achieve the higher level of success, which can take place of gate valves, check valves and throttle valves in software.
Ball valves are commonly used in aerospace, petrochemical, pipelines, food and drink and construction.Get more information about ball valves and about the material that is used to made ball valves on Mueller Stopper Fittings.
The Key Characteristics of Ball Valves:
- Low Flow Resistance: The passing of ball valve can be split into complete port and reduced port. Whether complete port or decreased port, its variable of flow resistance are smaller, particularly the full-port type. The passage diameter of this full-port ball valve is just like the pipe diameter which produces the partial resistance equivalent to friction resistance of the pipe.
- Great Sealing: At the moment, the majority of the sealing element is made from flexible materials like Polytetrafluoroethene, PTFE. Sealing element along with metal and non-metal substances is known as soft sealing. Broadly speaking, the effectiveness of soft sealing is not difficult to guarantee, and it needs low machining precision and rough surface.
- Longer Duration: The self-lubrication characteristic of PTFE lessens the friction between sealing component and ball.
