An Air Valve is a specialized valve used in pipelines to automatically release trapped air or admit air during filling and draining operations. By removing air pockets, it prevents flow restrictions, water hammer, and pressure surges, ensuring smooth and efficient pipeline operation. Air valves are essential in water supply systems, sewage networks, irrigation pipelines, and industrial fluid systems. They improve system efficiency, protect pumps and equipment, and reduce maintenance costs. Air valves are available in various types, including air release, air vacuum, and combination valves, to suit different pressure and flow conditions.
