Ball valve has the smallest fluid resistance in all valves|||
Thrust bearing reduced the friction between stem and other parts, and make the stem works flexibly |||
Good sealing performance at the valve seat,with PTFE, and the ball valve sealing capacity increased with the medium pressure increases. |||
Reliable stem sealing, the valve stem rotates not do lifting movement, sthus tem packing seal is not easy to destroy, and the sealing ability increases with medium pressure increases |||
For the PTFE material has good self lubrication feature, the friction loss is small, thus ball valve has long life-span |||
