  • Pneumatic segmented ball valve Featue

    Pneumatic segmented ball valve is a kind of ball valve.Pneumatic segmented ball valve has the same sealing performance as a normal ball valve, and it has both regulating and on off functions.The disc of Pneumatic segmented ball valve is a hemisphere with a V-shaped notch and there is a sharp edge on the V-shaped notch.

    During the rotation of the ball for Pneumatic segmented ball valve ,there is a wiping action between the closing discs, which has a strong cutting force to the medium.There forms a sectoral area between the v-shaped notch of the ball and the valve seat flow passage.The cross-sectional area of the flow channel of Pneumatic segmented ball valve can be changed during the rotation process to form a precise control of the medium.
