Stainless steel floating ball valve, stainless steel ball valve, Q41 ball valve, ball valve for opening and closing with a circular through-hole sphere, the sphere with the turning of the stem to the valve opening and closing movement. 
 The main advantage of the ball valve 
 (1) fluid resistance is small, fully open when the sphere channel, equal to the cross-sectional area of ??the body channels and the connection pipe and into the same straight line, the medium flow through the valve, equivalent to flow through a straight pipe of the various types of valves The ball valve fluid path of least resistance. 
 (2) open and close quickly, simply open and close when the sphere is converted to 90 degrees, convenient and rapid 
 (3) structure is simpler, smaller, lighter. In particular, its height is much smaller than the gate and globe valves. 
 (4) sealing performance. The ball valves generally use flexible soft seals. 


 The ball valve is an important class of valve, widely used in petrochemical, long-distance pipeline. The ball valve shut down a perforated sphere (or part of the ball), sphere rotation, with the stem to achieve the valve open or closed. 
 The ball valve rotated 90 ° can be fully closed to fully open, with the same specifications of the gate valve, globe valve, ball valve, small size, light weight, easy to pipe installation. 
 Seal demanding occasions, typically used to control gases, liquids, steam media suitable for control of sewage and contain fibrous impurities in the media, widely used in petroleum, chemical, metallurgy, light industry, papermaking, power plant, cooling and other work areas.
