Worm Gear Type Full Welded Ball Valve
Product overview
Fully welded ball valves are widely used in various fields.The superior quality and high performance stability is the common cast steel ball valve which can not be achieved, the service life is far greater than the steel ball valve, Fully welded ball valve is widely used in city gas, city heating, petrochemical, shipbuilding, steel, power plants and other types of station, pipeline equipment. The fully welded ball valve can be directly buried under the ground. No large valve well can be built to reduce the project cost, and it can also avoid the injury to the valve when running the valve. The fully welded ball valve can run reliably for a long time. Compared with the same specification products of the same industry, the valve body is small and the shape is beautiful.
Product details
Product Features
Fully welded ball valve are one-piece fully-welded ball valve, no external leakage phenomenon, because the seat is made up of PTFE seal ring and spring, it is adaptable to the change of pressure and temperature, and no leakage is produced within the range of use. The processing of the ball has an advanced computer detector tracking test, with high precision of the ball. As the material of the valve body is the same as the material of the pipe, the stress is not uneven. It will not cause the deformation due to the earthquake and the vehicle passing through the ground, and the pipeline is aging. The sealing ring is made of PTFE material with 20%C (Carbon) content to ensure no leakage (0%).
