The Single Orifice Air Valve is used in water line systems, oil pipelines and other liquid transmission lines and distribution lines to release the unwanted air accumulation. The sizes, dimensions, shapes, types, pressure capacities and other properties of the valves range with the standards. The 80mm Cast iron Single Orifice Air Release Valve is a medium size valve that is used in most systems. The material can vary from cast iron to carbon steel and alloy steel based on the material that is supposed to flow through the system.
A Single Orifice Air Valve will continuously release accumulated air during system operation. As air from the pipeline enters the valve, it displaces the water, allowing the float to drop. The air is then released into the atmosphere through a small orifice. As the air is vented it is replaced.
