AWWA Gate Valve

An AWWA gate valve is a resilient-seated or metal-seated linear-motion isolation valve manufactured, dimensionalized, and pressure-tested in strict compliance with American Water Works Association standards (AWWA C509 or AWWA C515). Cast from high-tensile ductile iron, it features an encapsulated rubber wedge that compresses against a smooth, cavity-free interior body to provide a 100% bubble-tight, zero-leakage shut-off in municipal water distribution mains. Conforming to standards like NSF/ANSI 61 and 372 (for lead-free potable water safety), these heavy-duty valves are primary specifications in municipal drinking water networks, fire protection mains, and wastewater collection systems, allowing civil engineers and municipal utility contractors to secure long-term infrastructure reliability by importing certified AWWA gate valves directly from leading manufacturers in China via our advanced B2B commercial platform.
