* Combines the features of both an air & vacuum valve and an air release valve.
* Air & vacuum component discharges large volumes of air during filling of the system.
* Air & vacuum component admits large volumes of air during drainage and at water column separation.
* The air release component releases entrapped air in pressurized systems.
* Dynamic design allows for high velocity air discharge while preventing premature closure.
* Innovative rolling seal mechanism.
* Available in sizes: 3/4", 1", 2" threaded male connections, NPT or BSPT.
* Working pressure range: 0.1-10 bar.
* Maximum operating temperature: 60°C.
* Maximum intermittent temperature: 90° C.
