Kinetic Air Valve -- Double Chamber Ductile Iron

Double-chamber kinetic air valves that handle both large-volume air discharge during pipeline filling and large-volume air intake during pipeline draining or column separation. The large orifice chamber vents air at high velocity during filling, then the small orifice chamber maintains continuous air release during operation. Anti-slam float design prevents water hammer when the large orifice closes. Ductile iron GGG50 body with epoxy coating for water and wastewater pipelines.
