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.

    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.
