Turbine Fully Welded Ball Valve

Q361F PN1.6-PN2.5 turbine fully welded ball valve is widely used in various fields. Its superior quality and high performance stability are not achieved by ordinary cast steel ball valves. The service life of fully welded ball valves is far greater than that of casting. Steel ball valves, all-welded ball valves are widely used in urban gas, urban heating, petrochemical, shipbuilding, steel, pressure regulating stations, power plants and other pipeline equipment.
