1.Application Area Purpose of Air Valve
2. Water Supply Pipelines Release trapped air to maintain full pipe flow and reduce pressure loss.
3. Sewage Systems Prevent vacuum and foul odors by admitting air during sudden emptying.
4.Irrigation Networks Prevent air locks and enable smooth flow over undulating terrain.
5.Hydropower Systems Protect penstocks from collapse by allowing air during turbine shutdowns.
6.Stormwater Systems Allow air in during rapid outflow, preventing pipe deformation.
7.Pump Stations Release air during startup and admit air during pump stop to prevent surge or collapse.
1. Public water distribution networks (to prevent vandalism or theft).
2. Critical infrastructure (e.g., reservoirs, treatment plants).
3. Above-ground air valves in urban or accessible areas.
4. Installed at high points on pipelines.
5. Used during startup (to release air) and shutdown (to admit air).
6. Prevent pipe collapse, water hammer, and flow disruptions.
