Single-chamber, double-vented air valve

Pressure:          PN10-PN40

Size:                DN50-DN200

In this type of valves, aeration operation occurs automatically in the main and secondary lines of water system networks.

Also the passage of liquid alone causes the operation of air valve.

The large vent is used for aeration and evacuation with high volume during filling and evacuation of the line.

The small vent is used for evacuation of the accumulated air when the line is working under pressure.

Scope of application: used for liquids with at least 0.3 times work pressure and up to 70°C.
