Which is better between stainless steel hollow ball and stainless steel solid ball?
In the design and manufacture of ball valves, in order to greatly save their design and processing costs! Ball Valves in low pressure pipelines are mostly cast hollow spheres; Stainless steel solid balls are definitely better than hollow balls. It is no doubt that the hollow ones used by Zhejiang manufacturers are only specially proposed. They will use solid ones. Large factories must use solid ones. The national standard requirements have never mentioned hollow spheres, which are manufactured by some manufacturers in order to save costs.
stainless steel hollow ball is made by Chinese people in order to reduce costs and cater to low prices. Ball valves include O-ball and V-ball valves, but there is no hollow solid ball. To say that the ugly point is to cut corners. Hollow spheres are relatively easy to round than solid spheres.
stainless steel hollow spheres are mostly cast, and solid spheres are forged; Hollow spheres are cheaper in cost than solid spheres, especially when stainless steel spheres are used, but the working condition changes in the pipeline easily make the hollow spheres change Center and fail to achieve the sealing effect.
