Sealing performance is critical to valve quality and system safety. OUWEI ball valves combine mirror-polished ball cores with high-performance seat materials to create a tight seal that eliminates internal and external leakage. We offer dual sealing solutions: soft-seat ball valves deliver exceptional sealing for clean media, while hard-seat ball valves resist high temperatures, wear, and erosion for severe industrial applications. Every OUWEI ball valve undergoes rigorous pressure testing to ensure long-term, maintenance-free reliability. #OUWEIBallValve #BallValvePrinciple #FlowControl #IndustrialValves #oilandgasvalve #API6Dvalve #Valve #OUWEI
