The AWWA C515 Ductile Iron Resilient Seated Gate Valve is specifically engineered for the demanding requirements of municipal water distribution and transmission mains. Unlike conventional gate valves that rely on metal-to-metal contact, this series features a fully vulcanized EPDM rubber encapsulated gate. When closed, the rubber compresses against a precision-machined body seat, creating a resilient seal that compensates for minor scratches or particles in the line. The valve body is constructed from high-strength ductile iron (ASTM A536 Grade 65-45-12), offering superior impact and tensile strength compared to gray iron. The non-rising stem design allows the valve to be buried directly underground without requiring a deep valve box, as the stem rotates without vertical movement.
