Air relief valve for clean water and neutral liquids to max. 60°C
AVK Anti Surge double orifice combination air valves allows air to enter the pipeline freely on separation, but control the expulsion as the column rejoins. This creates an air buffer that effectively reduces the impact velocity and the surge potential of the system. The second orifice automatically discharges accumlated air during normal working condtions.
