Products Name:Worm Gear Welded Ball Valve
Product Usage of Worm Gear Welded Ball Valve
Q361F PN1.6-PN2.5 all-welded ball valve is widely used in various fields, its superior quality and high-performance stability is not common cast steel ball valve, all-welded ball valve life is far greater than the cast 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 types of pipeline equipment.
Features of Worm Gear Welded Ball Valve
1. All-welded ball valve, there will be no external leakage and so on. Sphere processing has advanced computer detector tracking test, so the ball of high precision machining.
2. As the valve body material with the same pipe material, there will be no uneven stress, it will not be due to earthquakes and vehicles through the ground when the deformation, the pipeline anti-aging.
3. The sealing ring body is made of RPTFE with 25% carbon content to ensure no leakage (0%) at all.
