Fully welded ball valves are widely used in various fields.Its superior quality and high performance stability can not be achieved by ordinary cast steel ball valves. Its service life is much longer than that of cast steel ball valves. Fully welded ball valves are widely used in various pipeline equipment such as city gas, city heat supply, petrochemical industry, shipbuilding, steel, pressure regulating station, power plant, etc.Fully welded ball valves can be buried directly underground without building large valve wells to reduce project cost and avoid personal injury when operating the valves. Fully welded ball valves can operate reliably for a long time.Comparing with the same specifications in the same industry, the valve body is small and has a good appearance.
Fully welded ball valves are one-piece, fully welded ball valves with no external leakage. Since the seats are composed of PTFE sealing rings and springs, they are highly adaptable to changes in pressure and temperature and do not cause any leakage in service.The machining process of sphere is tracked and detected by advanced computer tester with high precision.As the valve body material is the same as the pipe material, there will be no uneven stress, no deformation due to earthquake and when the vehicle passes through the ground, and the pipe is aging resistant.The sealing ring body is made of PTFE with 20% C (carbon) content to ensure no leakage (0%).
