OUWEI fully welded ball valves utilize integrated welding technology, with the valve body made of the same material as the pipeline, completely eliminating the risk of external leakage. Their PTFE sealing rings combined with spring-loaded valve seats can adapt to drastic changes in pressure and temperature, ensuring long-term stable operation of gas transmission pipelines. OUWEI valves feature a direct burial design that eliminates the need for large valve pits, significantly reducing construction costs and safety risks in urban gas projects.#BallValve #EmergencyShutdownSystem #ZeroLeakageSealing #HighPressureHighTemperatureValve #PetrochemicalValve #GasTransmissionValve #API6DStandard #Ouweivalve #Valve
