Quick Details
The double orifice automatic air valves with integrated valve are used for applications related to troubles
with air in the pipelines. The double air valves with integrated valve working as isolating valve allow maintenance
or replacement of balls in line.
The minimum pressure on seat is 0,3 bar.
The double ball air valves have three functions:
Discharge large amount of air during filling operations
Discharge small amount of air during working operations
Let air in during piping emptying operations

In general only when the air release function is required, it can be combined with Air valves for the kinetic
functions of air outflow and inflow.
Air valves:
Air valves in pipeline systems serve two primary functions.
1.The first is the release of accumulated air that comes out of solution within a pressurized pipeline. This air will
result in bubble formation, which will gather at localized high points along the pipeline profile. This air accumulation will
occur when the bubble’s buoyancy is greater than the energy to convey the bubble with the liquid.
Air valve used to release this free air is known as an air release valve.
2.The second function of an air valve is to admit air into the system when the internal pressure of the pipeline
drops below atmospheric pressures. By admitting air into the pipeline as the internal vacuum condition develops,
the magnitude of the vacuum pressure can be reduced and as a result help prevent the pipeline from experiencing excessive
deflection and/or collapse as well as help prevent the formation of a full vacuum condition in which vapor cavities may form
the fluid vaporizing.
Air valves can contribute to the improvement of the efficiency of the water system.
