Leakage remains the top threat to safety and efficiency in oil, gas and urban gas pipelines. OUWEI fully welded ball valves adopt an integrated seamless welding design that eliminates flanges and bolts, fundamentally preventing external leakage.
With precision‑machined spheres and high‑performance seats, they deliver consistent zero‑leakage performance across extreme temperatures from ‑196°C to 650°C, even under high pressure, corrosive and flammable media. OUWEI craftsmanship secures global industrial pipeline safety. #OUWEI #FullyWeldedBallValve #ZeroLeakage #PipelineSafety #OUWEIValve #Valve
