The inside of the hollow ball plug is hollow, which is usually cut to length from seamless steel pipe or straight seam welded pipe, and then pressed into a ball blank, and then the finished sphere is processed into a hollow ball plug. This type of hollow ball has no inner wall or stiffeners, and is suitable for bores from 40mm to 300mm in diameter. Hollow ball plugs save material and processing costs. Usually, small diameter hollow balls are used in medium and low pressure all-welded ball valves.
