Description of Hollow Valve Balls and Steel Plate Welded Valve Balls

The hollow of the ball valve means that the valve core inside the valve body is hollow, the valve core can be made into solid or hollow, according to the needs of customers, as well as cost control, the general valve core is 304 stainless steel. Hollow valve balls are

Hollow valve spheres are divided into two types according to their structural characteristics:

1: There is no inner sleeve welded inside. The ball blank is directly pressed into a sphere by a straight seam welded pipe or a seamless pipe, and then processed into a sphere. Usually such hollow spheres are floating spheres.

2: There is an inner sleeve welded inside. The ball blank is directly pressed into a sphere by a straight seam welded pipe or a seamless pipe, and then the welded pipe or seamless pipe is welded in the sphere to form the inner hole of the valve sphere. The groove of this kind of sphere is generally dominated by a moon-shaped groove, and the sphere is also a floating sphere. If the bore size is large, the sphere and the inner sleeve are directly formed by the steel plate, which is formed by coil welding according to the shape and size required by the drawing. The maximum diameter of this sphere can reach 1600MM. Usually, the spheres are fixed spheres. .

Any drawings of hollow balls need to note the wall thickness requirements, so that our factory can make accurate quotations! If you have an inquiry for this kind of sphere, please don’t hesitate, we are the most professional!
