Industrial trunk pipelines and municipal main energy pipelines require large‑diameter valves with high stability and strong flow capacity. Ouwei fully welded ball valve supports customized production of multiple large‑diameter specifications, adopting integral thickened steel plate welding forming to ensure overall structural strength of large‑size valves.The optimized large‑flow ball channel design guarantees unobstructed high‑volume fluid transmission, matching the operating demand of main pipeline systems. Precision integral welding technology eliminates welding deformation of large‑diameter valve bodies, ensuring accurate matching and tight sealing. Strictly tested by high‑pressure and medium‑impact experiments, Ouwei valves can stably undertake long‑term high‑load operation of oil, gas and water main pipelines, supporting large‑scale industrial and municipal energy transmission. #Ouwei #LargeDiameterValve #MainPipelineValve #HighFlowValve #FullyWeldedBallValve
