The key words of this product: Valve Balls Hollow Balls Welded Balls
Due to the low pressure of pipe/ tube, and the medium is usually waters, steam, fuel gas, etc. with normally working pressure PN0.1 to PN25 bars, so the coventional floating design ball valves are mostly applied. From point of view of cost, the hollow valve can save 40%~70% than the solid balls with the same specification.
