Welded ball valve are widely used in underground gas pipelines, natural gas transmission, pressure regulating stations and other fields.
The whole structure of the valve adopts the process structure of full welding, which greatly improves the internal and external sealing of the valve and greatly reduces the weight of valve (especially below DN300), which makes the installation of the valve more convenient and not only reduces the cost of engineering construction, but also saves time.
