Municipal water supply and wastewater systems feature large diameter, low pressure and medium with suspended impurities. OUWEI butterfly valves adopt ductile cast iron body with epoxy coating for strong corrosion resistance. The EPDM integrated seat ensures bidirectional bubble-tight sealing and long durability. Compact and lightweight structure reduces installation space and fluid resistance, improving pipeline efficiency. The valves support easy operation and low maintenance cost, widely used in water plants, sewage treatment stations and urban pipe networks for stable regulation and on-off control. #OUWEIbutterflyvalve #waferbutterflyvalve #municipalvalve #watertreatmentvalve #EPDMseatedvalve #Valve #OUWEI #OUWEIValve
