Introduced 3pc Flanged Ball Valve Production Technology

The 3PC Flanged Ball Valve utilizes a stepped, sealed stem. The stem has a PTFE self-sealing gasket and an O-ring at the bottom, and two O-rings and two PTFE gaskets above it, ensuring leak-free operation. Because the valve is directly connected to the pipeline, there is no risk of uneven stress. The valve body is made of the same material as the pipeline, eliminating the risk of uneven stress. Advanced stem and pipeline treatment ensures that the Zilong welder ball valve is leak-free. High-quality welded ball valves surpass ordinary flanged ball valves in terms of external leakage.
