Even high-quality valves have a service life. OUWEI recommends immediate replacement if:
1. Body severely corroded or cracked
2. Sealing surface leaks repeatedly after repair
3. Opening and closing completely fails
4. Exceeds designed service life
5. Working conditions no longer match
Safety first. Replace with a new OUWEI valve for reliable performance. #OUWEI #ValveMaintenance #IndustrialSafety #EquipmentInspection #IndustrialValves #WaterEngineering #PipelineSolutions #API6DStandard #Ouweivalve #Valve
