Double Orifice Metal Air Valve

A double orifice air valve is an essential component in water distribution systems that helps regulate the flow of air and release excess air or gas that can accumulate in pipelines. This type of air valve consists of two separate orifices or openings. One orifice is designed to expel air and gas from the pipeline, while the other serves as an inlet to allow air to re-enter when the pipeline is emptying or filling with water.
