Pneumatic segmented V notch ball control valve

Pneumatic segmented V notch ball control valve Overview:
Pneumatic segmented V notch ball control valve is compased of pneumatic actuator (double acting or single acting) and V notch segmented ball valve (flange type or wafer type) has the V type gap in the segmented ball valve plug which will do wedge-shaped sheared action when the Pneumatic segmented V notch ball control valve is closed, which not only has self-cleaning function but also can prevent being stuck from the dirt between plug and seat. The Pneumatic segmented V notch ball control valve is not only for the general media but also special for controlling the medium of slurry, drainage, fiber and small particles.
Pneumatic segmented V notch ball control valve equipped with pneumatic or electric actuator can meet various control requirements, Pneumatic segmented V notch ball control valve is widely used in the control systems of electric power, petroleum, chemical, metallurgy and papermaking.
