Structural features
All-welded ball valve is a one-body all-welded ball valve without external leakage and other phenomena. Since the seat is composed of PTFE sealing ring and spring, it has strong adaptability to pressure and temperature changes and will not produce any leakage within the service range.The machining process of the sphere is tracked and detected by the advanced computer detector, so the machining precision of the sphere is high.As the valve body material is the same as the pipe material, there will be no uneven stress and deformation due to earthquake and vehicle passing through the ground, so the pipe is anti-aging.The sealing ring body is made of PTFE material with 20%C(carbon) to ensure complete leakage (0%).
