The advantages of ball valve

Ball valve is fixed, does not produce mobile after compression. The fixed ball valve with floating seat, after the medium pressure, mobile seat, make the seal compression on the ball, to ensure the seal. Usually mounted on the upper and lower shaft with ball bearing, the operating torque is small, suitable for high pressure and large diameter of the valve.
To reduce the number of ball valve operating torque and increase the reliability of the seal, and in recent years the oil seal ball valve, both between the sealing surface pressure note special lubricating oil, to form a layer of oil film, which increases the sealing, and reduce operating torque, suitable for high pressure, large diameter of the china check valve.
Ball valve globe is elastic. Ball and seat sealing ring is made of metal material sealing pressure ratio is large, depending on the medium itself already could not reach the requirements of sealing, pressure must be applied force. This valve is suitable for high temperature and high pressure medium.
China ball valve is on the lower end of the sphere wall open one elastic slot, and elasticity. When close the channel, sphere rolling out with stem wedge-shaped head pressure to seal with the valve seat. Wedge-shaped head before you turn the sphere are released, the sphere then restore the original prototype, appear very small clearance between the sphere and china ball valve, can reduce the sealing surface friction and operating torque.
1. The fluid resistance small, basic no full size of the ball valve flow resistance.
2. Simple structure, small volume, light weight.
3. Compact and reliable. It has two sealing surface, and the widely use of all kinds of plastic ball valve sealing surface of materials, good sealing, can realize completely sealed. Have been widely used in the vacuum system.
4. Easy to operate, open and close quickly, from open to close as soon as rotate 90 , facilitate long-distance control.
5. Easy maintenance, the ball valve has simple structure, sealing ring are generally active, removal of replacement is more convenient.
6. In the full open or full close, sphere and valve seat sealing surface and the dielectric isolation, medium through, does not cause the valve sealing surface erosion,pneumatic control valve.
7. Applicable scope wide, size from small to several millimeters, big to a few meters, from high vacuum to high pressure can be applied.
8. wipe because of ball valves in the process of opening and closing and so can be used to take in the medium of suspended solid particles.
