1” Continuous Acting Vacuum Guard Air Vent


1” Continuous Acting Vacuum Guard Air Vent
Discontinued

The 1” continuous air relief valve is installed with an irrigation system to allow continuous relief of pressure from air pockets during operation, preventing pipes and fittings from cracking or bursting. The air relief valves can reduce the chance of water hammer damage caused by a sudden reversal of water flow. The air valve float design ensures the valve closes as water fills the system and remains open when air pressure reaches 7 PSI.

Part #: A190

In any irrigation system trapped air bubbles can damage pumps (via cavitations) and disrupt the flow and pressure in the system. Installing an air relief valve in an irrigation system allows the release of large volumes of air as water flows through the pump, pipes and filtration system, either along or at the ends of the main line. A continuous relief valve insures that pockets of air are continuously released during operation, reducing vacuum effect at shutdown.
