2、 Particle wear resistance: in the process of closing, only at the last minute, the crown will lean towards the ball seat, without friction, using the principle of double eccentricity.
Moreover, the sealing ring on the seat is surfacing with wear-resisting self-lubricating alloy, which is not easy to wear out and be washed out. The knife-shaped ball mouth has the function of cleaning and shearing between the ball crown and the seat, which is not easy to scale.
4、 適合高流速介質：因球體隱藏在閥腔的壹側而形成直通流道無流阻，堅固的偏心固定曲軸，在高流速的介質中無振動、無噪音。
8、 In some special occasions, the valve during rush repair can not affect the normal operation of the pipeline system, as long as the ball assembly after the rapid closure of the upper mouth can immediately restore the pressure of the pipeline operation, so that the rush repair valve caused by the loss of benefits to a minimum.
