Plastic Air Vent
Code: AV0134/ AV0110
Products details:
Air and vacuum control is essential to the safety, longevity, efficiency, and performance of an irrigation system. Air must be allowed to exit pipelines 1) upon startup to prevent water hammer, 2) during normal operation to prevent
the development of air pockets, and 3) air must be allowed to enter pipelines and laterals at shut down to prevent vacuum suction. Various types of valves
and vents are available to perform these functions.
Removal of Air from Pipelines
Avoid Water Hammer: Air must be allowed to escape pipelines at the same rate as water enters the pipeline during system startup to avoid dangerous water hammer from occurring.
Remove entrained or dissolved air:
Air that has accumulated at high points during system operation must be allowed to
escape to avoid air pockets which restrict the flow of water and can cause water hammer.
Allow the Entry of Air into Pipelines
Prevent Vacuum Suction in Pipelines:
Air must be allowed to re-enter main and submain pipelines as water drains during
system shut down to prevent negative suction from occurring and potential collapse of the pipelines.
Prevent Vacuum Suction in Laterals:
Laterals which are buried or submerged in water may ingest dirty water and/or soil
through the emitters as a result of vacuum suction if air is not allowed to enter the
laterals during system shut-down and drainage.
