Worm gear fully welded ball valve is free from external leakage and other phenomena. Since the valve seat is composed of carbonized Teflon sealing ring and coffee spring, it has strong adaptability to changes of pressure and temperature, and no leakage will occur within the range of marked pressure and temperature.The machining process of the sphere is tracked and detected by the advanced computer detector, so the machining precision of the sphere is high.Because the valve body material is the same as the pipe material, there will be uneven stress, will not be due to the earthquake and vehicles through the ground deformation, anti-aging pipeline.The sealing ring body is made of PTFE with 20%C(carbon) to ensure no leakage at all.
