    Product characteristics

    Flange welded ball valves, there will be no external leakage and other phenomena, because the valve seat is composed of fluorocarbon seal rings and coffee springs, in order to adapt to pressure and temperature changes, the labeling pressure and temperature range will not produce any slip. The processing process of sphere has advanced computer detectors to track and detect the sphere, so that the processing accuracy of sphere is high. Because the valve body material is the same as the pipeline material, there will be uneven stress, no deformation due to earthquake and vehicle passing through the ground, pipeline aging resistance. The sealing ring body is made of PTFE material with 20% C (carbon), which ensures no leakage.
