Pneumatic actuated stainless steel segmented ball valve

Pneumatic actuated stainless steel segmented ball valve Overview:
Pneumatic actuated stainless steel segmented ball 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 actuated stainless steel segmented ball 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 actuated stainless steel segmented ball valve is not only for the general media but also special for controlling the medium of slurry, drainage, fiber and small particles.
Pneumatic actuated stainless steel segmented ball valve equipped with pneumatic or electric actuator can meet various control requirements, Pneumatic actuated stainless steel segmented ball valve is widely used in the control systems of electric power, petroleum, chemical, metallurgy and papermaking.
