Double orifice air valve is designed to efficiently release trapped air during pipeline filling and allow large volumes of air intake during draining, preventing vacuum formation and pipeline damage. It features two separate orifices for small and large air discharge, ensuring reliable operation under varying pressure conditions. Commonly used in water supply, irrigation, sewage, and industrial systems, it improves flow efficiency, reduces noise, and enhances overall pipeline safety and durability.
