Stainless Steel Standard All-Welded Ball Valve
Steel all-welded ball valve in the pipeline is used to cut off, distribute and change the flow direction switch. With a unique float design, the sealing ring is pressed against the float, and the pressure in the pipe ensures that the valve is completely sealed inside and out. Due to the perfect sealing performance of the ball valve design, the installation and maintenance cost is very low during the installation and operation, and no spare parts need to be replaced.

Product Description
Fully welded ball valves are widely used in various fields. Its superior quality and high performance stability is the ordinary cast steel ball valve can not reach, its service life is much longer than cast steel ball valve, widely used in urban gas, urban heating, petrochemical, shipbuilding, steel, regulating stations, power plants and other types of pipeline equipment. It can run reliably for a long time and needs maintenance. It is simple to install, and other valves are more convenient to install.
