Product Description

Ball valve is the s was a valve, in half a century of time, ball valve has become one of the main valve class. Ball valve is mainly used for truncated or connect medium, can also be used to regulate and control of the fluid, V type ball valve can be more precise flow regulation and control, and is used for distribution medium tees ball valve and change the direction of the medium. Compared with other valve class, ball valve has the following advantages: some of the
1, fluid resistance small, ball valve is all of the fluid in a kind of least resistance, even shrink diameter ball valve, its fluid resistance also is fairly small.
2, switch quickly, convenient, as long as the valve rod rotation *0 °, ball valve can complete the full open or sexual action, it is easy to achieve rapid opening and closing.
3, sealed performance is good. Ball valve seat sealing generally USES the ptfe etc elastic materials manufacturing, easy to guarantee seal, and the ball valve sealing force with the medium pressure increases.
4, stem sealing is reliable. Ball valve opening and closing only when the stem rotation movement, so stem packing seal is not easy to be destroyed, and the stem seal sealing force with the fall of the medium pressure increased.
5, ball valve opening and closing only *0 ° turns, so do to realize automatic control and the remote control, ball valve can be equipped with pneumatic device, electric device, hydraulic device, gas to liquid interlock or electric hydraulic linkage device.
6, ball valve channel level off is smooth, not easy deposition, can the medium pipeline ball.
