Particularly high-tech nano-ceramic material sealing, hardness HRA90 ~ 94, its hardness and wear resistance of diamonds to the world, only in comparison with it.
    Cut self-cleaning ability, excellent sealing performance: a special sealing design, which make the valve opening and closing rotary motion in the superior row of the opposite sex, can easily cut the clear sealing surface attached to foreign bodies, sediment, scale in other, non-stuck phenomenon, which is the most significant half-ball valve features.
    Light and open and close quickly, the pressure loss is small: the principle of asymmetric structure with the spherical sealing a rapid separation in the open, low coefficient of friction, installation and maintenance easy. After opening the valve spool hidden in the side of the body cavity, the fluid through the flow area larger than the cut-off valve, butterfly valve damping, the pressure loss.
    Body deposition in the chamber did not cause caking of dead media to overcome the gate valve, ball valve valve, globe valve and so easy to scarring, easy to plug and easy to leak, short life and other defects, shows its unique advantages can always keep the valve normal opening and closing and regulatory function.
