Ball valves are mainly used to cut off or turn on the line of medium, can also be used to regulate and control the fluid, which has a strong hard seal between the valve V-ball core with its V-shaped carbide hardfacing metal seat shear iron ball, especially for fiber-containing tiny particles of solid material and other media. The multi-way valve in the pipe can not only control the confluence flexible medium, diversion, and flow switch, but also to close any channel leaving the other two channels are connected. This type valve in the pipe should generally be installed horizontally. The ball valve is elastic. Ball and seat ring are made of metal materials, sealing pressure than large, rely on the media itself has reached less pressure sealing requirements, must apply force. This valve is suitable for high temperature and high pressure medium. Elastic sphere is the sphere in the lower end of the inner wall of the tank valve open a resilient, and access flexibility. When closing the channel flanged ball valves, wedge-shaped head with the stem so that the ball up on and the valve seat seal. Before turning the ball to loosen the wedge-shaped head, the ball along with restoration of the original prototype, so that small gap, sealing surface can reduce friction and operating torque between the ball and seat.
