Cinder ball valve working principle is to rely on the rotary valve Love valves smooth or occlusion. Pneumatic ball valve switch is lightweight, small size, can be made into a large caliber, reliable sealing, simple structure, easy maintenance, sealing surface and the spherical often in the closed state, is not easy to be medium erosion, has been widely used in various industries. Pneumatic unloading gray valve and plug valve is the same type of valve closure is a sphere, a sphere around the body centerline rotation to achieve open, closed a valve. Pneumatic dust unloading valve mainly used to cut off the fast distribution and change the media flow direction in the pipeline. Pneumatic ball valve is a new type of valve in recent years has been widely used.
