        fully welded ball valve

        Product Characteristics

        1.Hebei Pingheng Valve Co., Ltd is authorized to manufacture and sales fully wdlded ball valve by UK OROKO Valve Co., Limited and by using their advance production technology.

        2.The Fully welded ball valve is wildly used in every fields in European and America countries. Its excellent quality and the stability of high-performance are unreachable for ordinary cast steel ball valves and its working life is much linger than cast steel ball valves. Full welede ball valve are widely used in city gas, city heating, petrochemical industry, shipbuilding, steel, offtake stations, power plants, and other pipeline equipments.

        3.Fully welded ball valve can be used long-term with reliable operation, needn’t maintain and easy to install (specifically under DN300). So the installation of the valve becomes more convenient, it’s not only reduces the cost of construction, but also saves a lot of time.
