    DN25 V Notch Pneumatic Wafer Type Ball Valve

    Wafer type segment ball valve ,V-Notch ball valve , pneumatic actuator segment ball valve


    Coosai wafer type segment Ball valve combines the advantage of globe control valve with the eccficiency of a rotary ball valve which satsfify the needs for throttle and shut off of flow within automatic process industry.The segment ball in V-notch design has strong cutting force and self-cleaning function.With the segment ball quarter turning the passage area changesin ectorial shape.Leading to the precise control of the flowm,it is the ideal valve for most paper and pulp process application,Low CV value precise control is available by special V-notch on DN25 Segment ball.


    Application:

    Pulp & Paper/ Petrochemical /

    Printing & Dying /Pharmacy/ Beverage & Food

    FEATURES

    1. Excellent sealing capacity-Class V Standard

    2. Splined connection between the shaft and ball ensures precise control and low hysteresis.

    3. Precise contouring of the V-notch provides excellent control characteristics for an extensive variety of flow applications.

    4. Easy to change seats,means low cost for valve repairs.

    5. Shearing action between ball and seal promotes smooth ,non-clogging operation-perfect for fiber or slurry applications.

    6. Spring loaded seat maintains constant contact with the ball,giving enhanced sealing performance.

    7. Heavy duty construction with unrestricted sreaight through flow path gives high Capacity.

    8. Superior trunnion bearing technology is engineered for excellent abrasion resistance.

    9. Rugged self-adjusting metal seated option is ideally suited for high temperature applications or slurries.
