High temperature ball valve QJ41S-16 has rotated 90 degrees to the action, cock body is a sphere, a circular through-hole or channel through its axis. Ball valve in the pipeline is mainly used to cut distribution and change the media flow direction, it only needs to be rotated 90 degrees to the operation and a small torque can be closed tightly. The most suitable valve for switch shut-off valve to use, but recent development has been ball valve designed to give it throttle and control the flow, such as V-ball valve. 
 The main features of valve is its own compact, reliable sealing, simple structure, easy maintenance, sealing surface and the spherical often in the closed state, is not easy to be medium erosion, easy operation and maintenance, applicable to water, solvents, acids, and natural gas and other general working medium, but also applies to poor working conditions of media, such as oxygen, hydrogen peroxide, methane and ethylene, has been widely used in various industries. Ball valve can be a whole, can also be combined.
