Traditional pipeline valves require regular gasket replacement, rust removal and sealing inspection, bringing high post‑operation costs for buried engineering. Ouwei fully welded ball valve adopts integral forging and full penetration welding process, with no exposed connecting gaps or vulnerable wearing parts. It realizes long‑term maintenance‑free operation after one‑time installation, greatly simplifying pipeline system management.Designed specifically for underground buried working environments, the compact welded body does not require large‑scale valve wells, effectively reducing engineering construction area and project investment. The extended valve stem allows ground surface operation while the valve body is buried underground, ensuring construction and maintenance safety. Adaptable to natural gas, hot water, industrial oil and various mediums, Ouwei valves are the cost‑effective choice for municipal and industrial long‑distance pipeline construction. #Ouwei #WeldedBallValve #BuriedPipelineValve #MaintenanceFreeValve #MunicipalEngineering
