Fully welded ball valve, there will be no external leakage and other phenomena.The processing process of the sphere is tracked and detected by an advanced computer detector, so the processing accuracy of the sphere is high.Since the material of the valve body is the same as that of the pipeline, there will be no uneven stress and no deformation due to earthquakes and vehicles passing the ground, and the pipeline is resistant to aging. The body of the sealing ring is made of RPTFE material with a content of 25% Carbon (carbon) to ensure no leakage (0%).
